Nanotechnology Now – ECHA Announces Two Decisions on … – Nanotechnology News

Home > Nanotechnology Columns > Bergeson & Campbell, P.C. > ECHA Announces Two Decisions on Appeals Related to Nanomaterials

Abstract: On June 30, 2017, the European Chemicals Agency (ECHA) Board of Appeal published two decisions related to nanomaterials.

July 6th, 2017

On June 30, 2017, the European Chemicals Agency (ECHA) Board of Appeal published two decisions related to nanomaterials. In the July 5, 2017, issue of ECHA Weekly, ECHA states that the Board of Appeal “largely upheld the appeals and annulled most of the requests for information.” See https://echa.europa.eu/view-article/-/journal_content/title/echa-weekly-5-july-2017 In Cases A-014-2015 and A-015-2015, registrants appealed the same 2015 ECHA decision requesting information on synthetic amorphous silica (SAS) following a substance evaluation by the Netherlands Competent Authority. See https://echa.europa.eu/web/guest/about-us/who-we-are/board-of-appeal/announcements/-/view-announcement/301/search/true and https://echa.europa.eu/web/guest/about-us/who-we-are/board-of-appeal/announcements/-/view-announcement/302/search/true ECHA requested information on the physicochemical properties and uses of different types of SAS and surface-treated SAS. According to ECHA, the Board of Appeal annulled these requests “as it was not clear how the information would be used to clarify the potential concerns which in any case had not been sufficiently demonstrated.” ECHA notes that the Board of Appeal upheld one request in the contested decision — for information on the inhalation toxicity of one type of SAS, following repeat exposure.

RED’s impending smartphone will assault your senses with nanotechnology for $1600 – imaging resource

by Jaron Schneider

posted Thursday, July 6, 2017 at 1:40 PM EDT

RED, the company known for making some truly outstanding high-end cinema cameras, is set to release a smartphone in Q1 of 2018 called the HYDROGEN ONE. RED says that it is a standalone, unlocked and fully-featured smarphone “operating on Android OS that just happens to add a few additional features that shatter the mold of conventional thinking.” Yes, you read that right. This phone will blow your mind, or something – and it will even make phone calls.

In a press release riddled with buzzwords broken up by linking verbs, RED praises their yet-to-be smartphone with some serious adjectives. If we were just shown this press release outside of living on RED’s actual server, we would swear it was satire. Here are a smattering of phrases found in the release. We can’t make this up:

Those are snippets from just the first three sections, of which there are nine. I get hyping a product, but this reads like a catalog seen in the background of a science-fiction comedy, meant to sound ridiculous – especially in the context of a ficticious universe.

Except that this is real life.

After spending a few minutes removing all the glitter words from this release, it looks like it will be a phone using a display similar to what you get with the Nintendo 3DS, or what The Verge points out as perhaps better than the flopped Amazon Fire Phone. Essentially, you should be able to use the phone and see 3D content without 3D glasses . Nintendo has already proven that can work, however it can really tire out your eyes. As an owner of three different Nintendo 3DS consoles, I can say that I rarely use the 3D feature because of how it makes my eyes hurt. It’s an odd sensation. It is probalby why Nintendo has released a new handheld that has the same power as the 3DS, but dropping the 3D feature altogether.

Anyway, back to the HYDROGEN ONE, RED says that it will work in tandem with their cameras as a user interface and monitor. It will also display what RED is calling “holographic content,” which isn’t well-described by RED in this release. We can assume it is some sort of mixed-dimensional view that makes certain parts of a video or image stand out over the others.

There are two models of the phone, which run at different prices. The Aluminum model will cost $1,195, but anyone worth their salt is going to go for the $1,595 Titanium version. Gotta shed that extra weight, you know?

Strangely, the press release moves away from the impersonal format and adds a a direct voice. The release states explicitly that, “I can also assure you that after this initial release, we will NOT be able to fill all orders on time due to display production limitations. We will NOT guarantee these prices at the time of release. Taxes and shipping not included in the price.” So like, better buy it now I guess.

The image of the phone is not final, as RED also states that the design may change, and that “specs and delivery dates can also change anytime for any reason.” Luckily, should you choose to put money down on this completely unproven and unseen product, “payments are fully refundable for any reason prior to shipping.”

Yes, I’m being hard on this product. I am not taking it seriously. Why? Because the release is totally ridiculous. The amount of marketing alphabet soup being thrown into this makes a prime target for my sarcasm gland, and certainly hard to take with any semblance of seriousness. Tech products, especially phones, fail all the time; even ones from well-known companies. Trusting a high-end professional camera company to make an expensive consumer device is already something to inspire a healthy amount of skepticism, but when it’s compounded with hype-heavy adjectives and made-up words, I am just put even further on the “wait and see” side of these tracks.

But if RED can produce, I’ll be happy to eat my own words and have my”SENSES” “ASSAULTED” by a $1,600 titanium phone powered by “nanotechnology.”

Self-replicating Nanobots could DESTROY all life on Earth, warn experts – Express.co.uk

GETTY

Nanobots, which are theoretical tiny robots a single nanometre wide one billionth of a metre are currently being worked on and in the future may dominate the planet if they get out of control.

They can be used for several purposes but boffins hope to use them mainly for in-body procedures, such as replacing cells in the body for fighting things such as cancer.

Such would be the technology that the nanobots would be able to act as if they are cells and self-replicate, most likely through protein folding, where they can split and create another version of themselves.

Louis A Del Monte, physicist and author of the book Nanoweapons, wrote in an article for the Huffington Post: You can think of them as the technological equivalent of bacteria and viruses.

GETTY

The minuscule bots are expected to arrive in the 2050s, according to Dr Del Monte, following the rise of artificial intelligence, which will help to create the revolutionary bots.

While experts are developing nanobots for the good, there are fear this could quickly get out of control.

Eric Drexler, an engineer who is considered one of the pioneers of nanotechnology, warned in his book Engines of Creation way back in 1986: Imagine such a replicator floating in a bottle of chemicals, making copies of itselfthe first replicator assembles a copy in one thousand seconds, the two replicators then build two more in the next thousand seconds, the four build another four, and the eight build another eight.

GETTY

At the end of 10 hours, there are not thirty-six new replicators, but over 68 billion.

In less than a day, they would weigh a ton; in less than two days, they would outweigh the Earth; in another four hours, they would exceed the mass of the Sun and all the planets combinedif the bottle of chemicals hadn’t run dry long before.

He goes on to warn that they could begin destroying and replacing all biological life on Earth leading to the end of humanity in what is known as The Grey Goo Scenario.

GETTY

Mr Drexler: Early assembler-based replicators could beat the most advanced modern organisms. ‘Plants’ with ‘leaves’ no more efficient than today’s solar cells could out-compete real plants, crowding the biosphere with an inedible foliage.

Tough, omnivorous ‘bacteria’ could out-compete real bacteria: they could spread like blowing pollen, replicate swiftly, and reduce the biosphere to dust in a matter of days.

Dangerous replicators could easily be too tough, small, and rapidly spreading to stopat least if we made no preparation.

We have trouble enough controlling viruses and fruit flies.

Chris Phoenix, Director of Research of the Center for Responsible Nanotechnology (CRN) however says that there are other things to worry about with nanotechnology.

Asus

1 of 9

Asus Zenbo: This adorable little bot can move around and assist you at home, express emotions, and learn and adapt to your preferences with proactive artificial intelligence.

He wrote in a paper titled Safe Exponential Manufacturing along with Mr Drexler, who has tried to distance himself from the grey goo scenario a term he coined: Runaway replication would only be the product of a deliberate and difficult engineering process, not an accident.

Far more serious, however, is the possibility that a large-scale and convenient manufacturing capacity could be used to make powerful non-replicating weapons in unprecedented quantity, leading to an arms race or war.

Policy investigation into the effects of molecular nanotechnology should consider deliberate abuse as a primary concern, and runaway replication as a more distant issue.

U of A uses nanotechnology to develop new test for aggressive prostate cancer – National Post

Alberta men diagnosed with prostate cancer could soon have a better blood test to help determine if they can bypass a painful and invasive biopsy.

The Alberta Prostate Cancer Research initiative claims its new blood test is 40 per cent more accurate at identifying men with aggressive forms of prostate cancer than the common prostate-specific antigen (PSA) blood test, which researchers say often leads to unneeded biopsies.

We know what we will really want in patients is to detect which patients are going to have metastatic cancer down the road because we need to cure them now, said Dr. John Lewis, a University of Alberta oncology researcher who helped develop the new test.

What were hoping is that if this test says they have aggressive cancer, they go ahead and get a biopsy to confirm. If it says they dont have aggressive cancer, they can potentially skip the biopsy altogether.

Lewis expects the new test to cost several hundred dollars. Compared with a biopsy that costs almost $2,000 and involves pressing 12 needles through the prostate, Lewis believes the blood test has the potential to provide significant savings to the health-care system and prevent side-effects from operations on men unlikely to develop aggressive cancer.

A patient who gets the new test, called the Extracellular Vesicle Fingerprint Predictive Score test, will have it done alongside the traditional PSA test.

The research team has been working for five years, studying the spread of prostate cancer. The new test takes advantage of advances in nanotechnology and machine learning to test for tiny fragments of prostate cancer in the bloodstream and recognize aggressive forms of cancer. The blood test was studied on 377 Alberta men who were suspected to have prostate cancer.

Lewis said there are plans to do more research, but hes confident this is the test theyll be taking to market. It will be sold though a university spin-off company called Nanostics Inc., founded by Lewis and three of his colleagues.

Nanotechnology can make biopesticides more effective

This means farmers would be required to use very small quantities of biopesticide in its nano form

The use of eco-friendly biocontrol agents as an alternative to chemical pesticides is prevalent in some farming communities. A group of scientists have now shown that it is possible to substantially enhance efficacy of such biocontrol agents by converting them into nanoparticles.

Researchers at the University of Agricultural Sciences at Raichur in Karnataka have developed a new technique to do so. They have converted secretion of a bacterium, Photorhabdus luminescens, into nanoparticles and found that its efficacy improved significantly. The bacterium is used as a biocontrol agent against a wide range of crop pests like mite, aphid, and mealy bug. The nano form of biocontrol agent has been tested against two sucking pests of cotton — Tetranychus macfarlanei, a species of mite and Aphis gossypii, a species of aphid.

Reporting their findings in a recent issue of scientific journal Current Science, the researchers noted, high mortality coupled with quick action emphasises the potential of nanotechnology in enhancing the pathogenicity of a microbial pesticide. It was found that very low concentration of nano-particulated secretion could kill pests as against unprocessed secretion. This means farmers would be required to use very small quantities of biopesticide in its nano form.

Cellular secretions of the bacterium Photorhabdus luminescens have been used as pesticide against a wide range of insects. The bacterium lives within the body of a nematode called Heterorhabditis in a symbiotic relationship with the nematode. It secretes an array of toxins and enzymes. The secretions have a wide range of insecticidal actions against both sucking and chewing anthropod pests of agricultural crops. Farmers spray solutions of the bacteria on crops but it is not as efficacious as synthetic chemicals.

Scientists converted bacterial secretions into nanoparticles using a multi-stage process involving culturing, centrifuge, ultrasonic assisted atomizing and hot air-assisted vacuum process. The resultant product is dry powder.

We have proved that it is possible to substantially enhance the efficacy of biopesticides. We need to conduct more studies to figure out what is the best form in which it could be delivered to the users: whether it should be as a powder or a solution or in some other form, said A. Prabhuraj, one of the scientists involved in the study.

The research team included Ramesh A.Kulkarni, J.Ashoka and S.G.Hanchinal of the Department of Agricultural Entomology and Sharanagouda Hiregoudar of the Department of Processing and Food Technology at the Raichur University. (India Science Wire)

Nanotechnology to protect astronauts from harmful radiation, and … – ABC Online

Updated July 05, 2017 11:57:18

Imagine a window that could instantly turn into mirror the possibility is real, thanks to a breakthrough in nanotechnology by researchers at the Australian National University (ANU).

They have developed a material that promises to protect astronauts from harmful radiation, as well as practical uses closer to home.

ANU researchers have dubbed their invention a “smart mirror”, and all that is needed for it to change is an adjustment to its temperature.

“Our smart mirror consists of lots of dielectric nanoparticles which are carefully designed and arranged within a single layer,” ANU lead researcher Dr Mohsen Rahmani said.

The layer of nanoparticles are spread so thin that they are just 0.00005 of a millimetre apart.

“Today’s technology, all optical silicates consist of the elements that work statically,” Dr Rahmani said.

“Which means they either transmit the light or reflect the light, or something in between.”

Until now, optical silicates have only achieved one function.

But with a switch in heat, this new one promises to transform to either absorb, reflect or emit light and radiation.

“By our technology, for the first time you can have a single element which can have all those functions at the same time, and you can control the light passing through or reflects,” Dr Rahmani said.

Dr Rahmani said the film was thin enough to coat a pin head hundreds of times, and could be applied to any surface like a spacesuit.

“By adjusting the temperature of that thin layer, we are able to control the optical properties of those nanoparticles,” he said.

“So that the entire surface can either transmit or reflect the incoming light on demand.”

One of the major problems involved with prolonged space travel is exposure to cosmic radiation.

Currently thick filter panels are needed to protect both space craft and astronauts.

“As we know, the temperature in space varies a lot,” Dr Rahmani said.

“Just imagine we can have a smart mirror which can reflect different frequencies at different temperature.

“It can give a great platform to protect the devices or astronauts in different environments in the space.”

Sending people into space has seen the creation of a number of innovations and inventions now used in daily life memory foam, quick-dry anti-rust paint, water filters, and some bulletproof fabrics all came from the space race.

And just like those innovations initially designed for space travel, this one also has useful applications on Earth.

Just like a car’s back window has wires running through it to defog it with a change in heat, a similar system has been proposed to control the temperature in the new film, switching clear glass to a mirror or an illuminated panel.

“The principle is quite extendable to other frequencies as well,” co-researcher and associate professor Andrey Miroshnichenko said.

“Including visible, which opens [a] whole range of new types of application, including architectural ones.

“Where for example, your window becomes a mirror.”

With mirrors switching to light panels, the ANU team said the technology also promises to save energy.

Using Nanotechnology for Space Elevators, Direct Cell Delivery – Edgy Labs (blog)

The infinitely small nanotech world helps science take great leaps forward, from therapeutic nanosystems treating the body to space elevators.

In recent years, advances in nanosciences have been so numerous and varied that they affect the progression of many different scientific fields.

Whether in physics, chemistry, biology, medicine or space, nanotechnologies help many scientific disciplines to overcome limitations. Harnessing the power of the very small enables the development of novel solutions and the revisiting of old concepts that until now remained inaccessible.

Here are two potential futuristic concepts, for space and medical applications, that were discussed by a panel of researchers and scientists at Future Con, held at the Walter E. Washington Convention Centerin Washington D.C. from June 16th to the 18th.

For over a century, space elevators have been heralded as a potential revolutionary space transportation system. In 1895, Constantin Tsiolkovsky, a Russian scientist proposed a celestial castle that would float in Earths geosynchronous orbit (GEO), attached to a high tower on the ground via cables.

Naturally, speculative writers have used variations of space elevators as plot devices. In his 1979 novel The Fountains of Paradise, Arthur C. Clarke describes the construction of the first space elevator in the 22nd century.

Imagine an elevator that goes a couple hundred miles up with nothing but wires to lift it from a ground station to one floating in space. The project sounds unfathomable, but thanks to nanotechnology, it is now scientifically viable.

Lourdes Salamanca-Riba, Professor at A. James Clark School of Engineering at the University of Maryland thinks that if cables were to be made from steel, the system would collapse under its own weight. Salamanca-Riba, who spoke at Future Con, proposed instead carbon nanotubes.

One-atom-thick carbon nanotubes (CNTs) are ultralight but extremely resistant and strong, which makes them perfect to make cables that carry the space elevator to a space base, 10,000 miles up.

With the longest synthesized CNT ever is 50 centimeters long, theres a long way to go until carbon nanotubes that can reach beyond Earths atmosphere are scalable.

Another panelist at the Future Con was Jordan Green, an associate professor at the Johns Hopkins University School of Medicine in Maryland, who made the observation that, in order to replicate, some viruses integrate their genes into the genome of a cell.

Green then discussed special nanosystems as a means to send genetic information to infected cells to cure them.

For some cancers and hemophilia, such systems could be used to genetically modify infected cell. By restoring and/or repairing genetic inadequacies or errors, affected cells can heal and regain their normal function withoutbeing destroyed.

For cancer, targeted gene therapycould encourage cancerous cells to halt malignant spread and even self-destruct.

Abstract: The Center for the Environmental Implications of NanoTechnology (CEINT) seeks comments on the NANoREG-proposed ISA-TAB-nano templates.

July 3rd, 2017

The Center for the Environmental Implications of NanoTechnology (CEINT) seeks comments on the NANoREG-proposed ISA-TAB-nano templates. See http://ceint.duke.edu/research/nikc/isa-tab-nano According to CEINT, the ISA-TAB-nano file sharing format, developed under the National Cancer Informatics Program Nanotechnology Working Group (NCIP NanoWG), is an accepted ASTM standard (ASTM International E2909-13). In 2016, the European Union NANoREG project adopted and adapted the ISA-TAB-nano format to organize consistently the results of their network of researchers. According to CEINT, to create the templates, NANoREG followed the logic of the original ISA-TAB-nano formatting, but drew upon relevant existing ontologies and extended it to incorporate additional endpoints and methods not addressed in the original standard. CEINT is working with researchers at Oregon State University and the NCIP NanoWG to update and extend the ISA-TAB-nano templates. CEINT seeks comments on the following proposed templates:

– Physical-chemical characterizations comment forms; – In vivo mammalian toxicity comment forms; – In vitro mammalian toxicity comment forms; and – General feedback regarding expanded (nonstandard) ISA-TAB-nano templates.

Comments are due August 1, 2017.

Combining Nanotechnology with Nature to Create Waterproof Coatings for Leather and Textiles – AZoM

Written by AZoMJun 27 2017

The production and consumption of consumer goods is constantly increasing in todays society. Goods are made and sold cheaply, break, or become obsolete quickly and are substituted in a cycle that produces huge quantities of waste.

The consumer cycle reduces the worlds natural resources and results in the production of huge quantities of waste to be disposed of frequently, at high cost to the environment.

Textile goods, such as shoes and clothes, are mostly problematic for the environment. Shoes and clothes can be manufactured and sold very cheaply; they are washed regularly and then unavoidably thrown away when they start to appear old.

Laundering clothes frequently adds to the already existing environmental concerns; excessive water and energy usage, pollution by detergents and the discharge of microscopic plastic fibers from synthetic fabrics all present a threat to the environment. One way of fighting the pollution and waste linked with the textile industry is by manufacturing goods that are easy to clean without detergents, durable and maintain their new appearance.1,2,3

In the recent years, there has been an increase in nanotechnology research, and nanotechnology has been incorporated into many applications in everyday life. The Nanotechnologists at Nanex have currently drawn inspiration from nature to create a new coating for textiles and leather that repels dirt and water, allowing the manufacture of shoes and clothes that are water-resistant, self-cleaning and durable. Self-cleaning clothes could positively influence the environment by minimizing energy consumption, water consumption and pollution from detergent and plastics fibers.4

The coating created by Nanex draws its inspiration from the properties of the lotus plant.4 Lotus plants grow in muddy, semi-aquatic environments, but have an inherent ability to remain dirt-free as their leaves are water-repellent and have self-cleaning surfaces.

When a water droplet falls on the surface of a lotus leaf, it beads up into a nearly perfect sphere and easily rolls off the leaf. As the water rolls off the leaf, it picks up and carries away any dirt or dust, resulting in a self-cleaning surface.5,6

To establish how water-repellent a surface is, Researchers study the shape that a water droplet makes on the surface, and the angle formed by the surface of the liquid and the contact surface, referred to as the contact angle.

The larger the contact angle, the lesser the liquid will spread on the surface, and the more water-repellent the surface is. A high contact angle with water (>90) is linked with a hydrophobic, water-repellent surface. Surfaces with a contact angle with water of more than 150 are called superhydrophobic surfaces. Both the lotus leaf surface and the surfaces covered in Nanex coating are superhydrophobic.7,8

The lotus leafs superhydrophobicity is due to the chemistry and the hierarchical topography of the leafs surface. When water falls on the leaf’s surface, the rough texture of the surface provided by microscale bumps results in trapped air and decreased contact between the surface and the water. Therefore, the attractive forces between the water molecules are more than the attractive forces between the surface and the water molecules, causing a water droplet to form.

Nanoscale hairs on the microscale bumps of the lotus leaf further decrease the contact between the surface and the water molecules, causing superhydrophobicity. Nanex coatings make use of nanostructures in a similar way to the lotus leaf, leading to the creation of water-repellent, self-cleaning textile surfaces.4-6

Shutterstock | aeiddam0853578919

Nanex coatings work in a similar manner to the lotus leaf. The coating covers every fiber of the original fabric and forms nanostructures on the surface of the fabric. When water falls on the surface, air is trapped by the nanostructures, and as the attractive forces between the water molecules are more than the attractive forces between the surface and the water, a droplet forms that slides off the surface, taking with it any dirt that is present.

Nanex coatings, thus, render the fabric water-repellent and protect against stains, while preserving the look, feel and breathability of the original fabric. Nanex coatings have already found many applications and can be applied using an aerosol to any natural fiber (see video). Jasna Rok and Elegnano have partnered with Nanex to create water and stain resistant shoes and clothing using Nanex coatings.9,10

In summary, consumerism results in many environmental problems including the depletion of energy, natural resources and water. Shoes and clothes that are washed regularly add to further detrimental effects on the environment due to pollution caused by plastics fibers and detergents.

Nature has inspired some Nanotechnologists to develop coatings that render leather and textiles water-resistant and self-cleaning, decreasing their environmental impact. Research at Nanex is currently focused on creating anti-odor sprays that eliminate odor particles, further minimizing the need to wash clothes.

Researcher awarded millions to develop nanotechnology drug delivery systems – EPM Magazine

A researcher at Case Western Reserve University (CWRU) School of Medicine has been granted two awards from the National Institutes of Health (NIH) to develop nanotechnology drug delivery systems for patients with breast cancer and those at risk of serious blood clots.

The R01 awards will be provided by the National Cancer Institute (NCI) and the National Heart Lung, and Blood Institute (NHLBI) to Nicole F Steinmetz, PhD, George J. Picha professor in biomaterials, member of the Case Comprehensive cancer Center and director of the Center for Bio-Nanotechnology at CWRU School of Medicine.

Nanoparticle engineering is an evolving field, with enormous potential in molecular imaging and therapeutics, stated Steinmetz. We are thrilled that the NIH is supportive of this new frontier in medicine.

From NCI, Steinmetz will receive a $2.2 million grant for the development of therapeutic nanotechnology specifically aimed at triple negative breast cancer patients. As triple negative breast cancer cells do not have surface receptors (commonly used by drug developers for therapeutic delivery) treatment options for about 15% of patients is limited.

Last year, Steinmetz and colleagues found virus-like particles from a plant virus (cowpea mosaic virus) that can stimulate the immune system to fight tumours and prevent outgrowth of metastasis. With the funding, Steinmetz and colleagues will explore the mechanisms behind the anti-tumour effects and develop dual-pronged therapeutic approaches through drug delivery strategies.

These plant virus-like particles have cancer fighting qualities on their own, but they can also be used as vehicles to encapsulate therapeutics, such as chemo- and immune drugs to synergise and potentiate the cancer immunotherapy, Steinmetz added. With the new grant, we will test whether combining the particles with breast cancer medications can combat breast cancer in mice.

Separately, the NHLBI will award $2.6 million for the development of nanotechnology to identify deep vein thromboses before they become fatal. We are developing a biology-derived plant virus nanotechnology, here using the tobacco mosaic virus, for molecular imaging and drug delivery, Steinmetz continued. The non-invasive MRI approach will allow us to gain molecular information about the thrombus, therefore, aiding prognosis. By integrating imaging and therapeutic capabilities, our approach will help diagnose patients, treat the disease and monitor disease progression over time.

The grants will be awarded this summer and will last for five years. If the projects are successful, they will be eligible for renewal.

Sunday conversation with Laura Brod, CEO or RoverMed BioSciences – Minneapolis Star Tribune

Aaron Lavinsky, Star Tribune Laura Brod, CEO, RoverMed BioSciences, oversees development of cutting-edge nanotechnology that promises to deliver drugs on a cellular level to fight cancer. A former state legislator and University of Minnesota regent, she uses her leadership and networking skills in the new venture.

Laura Brod has trod an unusual path into biotech, so perhaps its not surprising that the company she leads is charting an unorthodox route for its ultrasmall precision-medicine technology. Several years ago Brod nearly entered the race for governor following a stint in the Legislature, but she changed course, serving as a regent for the University of Minnesota and becoming CEO of a Minnetonka company called GeneSegues Therapeutics, which was developing medical nanotechnology for cancer. Today Brod is also CEO of a spinoff company based in St. Cloud called RoverMed BioSciences, which is working to apply GeneSegues technology to a broader array of diseases.

Q: Tell me about your companys technology.

A: RoverMed has developed a nanotechnology that aims to deliver the next generation of drugs. There are a number of therapeutics being developed by pharmaceutical companies that will never actually impact humans unless they have a precision-targeted delivery technology that is able to bring them directly to the disease cell. And that is what RoverMed does.

Nanotechnology in the food industry is expected to nearly triple in value to $20.4 billion by 2020, with several emerging areas for innovation, reports New Food Magazine.

Engineered nanotech compounds could offer great benefits in ingredients particularly for increased solubility and bioavailabilityas well as in food packaging with antimicrobial surfaces and sensors that change color when food begins to degrade.

In the food sector, there has been a 40% increase in publications and a 90% increase in patent filings involving nanotechnology in the past two decades. More than 1,000 companies now have an R&D focus on nanotechnology-based products. Future applications could include immobilizing enzymes to improve their efficiency and reuse, and using nanoscale structures to create new food textures.

Nanotechnology refers to controlling compounds on a molecular scale measured in nanometers, or millionths of meters. In the food industry, the technology has excited manufacturers as its potential uses have been explored, such as producing stronger flavors or colors, improving the bioavailability of nutrients, and detecting bacteria in packaging.

However, early enthusiasm from researchers and product developers was met with pushback from consumers who were concerned about the technologys safety. Since then, the FDA has released guidelines on using nanotechnology in food, but the industry has been wary about how it communicates nanotech-based innovation with consumers.

Nanoscale compounds in food are not new. They exist naturally in milk,with nanoscale casein particles responsible for its fat stability. Meanwhile,more than 1,600 consumer products contain engineered nanoscale particles, according to an inventory run by The Project on Emerging Nanotechnologies. They are already widely used in the food packaging sector to help ensure food quality and safety. Nanotech-based sensors can detect and measure the presence of oxygen or bacteria, such as listeria.

In the ingredient sector, nanotechnology is still more widely used in supplements. However,nanoencapsulation could be used to protect sensitive compounds like vitamins, minerals, antioxidants and polyunsaturated fatty acids so they could be delivered only when they reach the gut. That would improve how they are absorbed by the body, and reduce their impact on a products taste and appearance.

Communicating the benefits of nanotechnology in food is still one of the industrys biggest challenges, and some say it is slowing development in the sector. However, with diverse applications covering everything from improved food safety to better nutrition, reduced food waste, and biodegradable packaging, it is inevitable that consumers will start to see more nanoscale compounds in consumer products in the coming years.

CWRU Researcher Awarded Over $4.7 Million to Develop Drug … – Newswise (press release)

Newswise Nicole F. Steinmetz, PhD, George J. Picha Professor in Biomaterials, member of the Case Comprehensive Cancer Center, and Director of the Center for Bio-Nanotechnology at Case Western Reserve School of Medicine, has received two major grants from the National Institutes of Health to develop microscopic drug-delivery systems for patients living with breast cancer, and patients at risk for serious blood clots.

The new R01 awards are provided by the National Cancer Institute (NCI), and the National Heart, Lung, and Blood Institute (NHLBI). Steinmetz plans to collaborate with fellow members of the Case Comprehensive Cancer Center (Ruth Keri, PhD, Julian Kim MD), Case Center for Imaging Research (Xin Yu, ScD), and the CWRU Cardiovascular Research Institute (Yunmei Wang, PhD, Daniel Simon, MD), as well as collaborators at Dartmouth Geisel School of Medicine (Steven Fiering, PhD) for the funded studies.

Nanoparticle engineering is an evolving field, with enormous potential in molecular imaging and therapeutics. We are thrilled that the National Institutes of Health is supportive of this new frontier in medicine, Steinmetz said.

As part of a $2.2 million NCI award, Steinmetz will develop therapeutic nanotechnology specifically for triple negative breast cancer patients. Triple negative breast cancer cells do not have receptors on their surfaces that are often leveraged by drug developers, severely limiting treatment options for about 15% of patients. But last year, Steinmetz and colleagues found virus-like particles from a plant viruscowpea mosaic viruscan stimulate the immune system to fight tumors and prevent outgrowth of metastasis. The new funding will allow Steinmetz and her team to explore mechanisms behind the anti-tumor effects and develop dual-pronged therapeutic approaches through drug delivery strategies.

Said Steinmetz, These plant virus-like particles have cancer-fighting qualities on their own, but they can also be used as vehicles to encapsulate therapeutics, such as chemo- and immune drugs, to synergize and potentiate the cancer immunotherapy. With the new grant, we will test whether combining the particles with breast cancer medications can combat breast cancer in mice. Steinmetz will also investigate how the size and shape of the virus-like particles influence immune cells, to identify characteristics that could be used to develop other therapeutic molecules.

A separate $2.6 million NHLBI award will enable Steinmetz to develop nanotechnology to identify deep vein thrombosesblood clotsbefore they become fatal. Deep clots can be difficult to spot until its too late, leading to tens of thousands of deaths annually in the United States. Even clots that are successfully found and disrupted often recur. According to Steinmetz, combining nanotechnology with MRIs could improve early diagnoses and guide therapeutic intervention.

We are developing a biology-derived plant virus nanotechnology, here using the tobacco mosaic virus, for molecular imaging and drug delivery. The non-invasive MRI approach will allow us to gain molecular information about the thrombus, therefore aiding prognosis, Steinmetz said. Steinmetz and her team will engineer the moleculeinjected into the bloodstream during MRIsto not only help doctors see blood clots, but also to disrupt clots and deliver medications. Said Steinmetz, By integrating imaging and therapeutic capabilities, our approach will help diagnose patients, treat the disease, and monitor disease progression over time.

Both grants begin this summer and provide funding for five years. If the projects are successful, they are eligible for renewal.

FG urged to adopt Nanotechnology in science, technology development – The Nation Newspaper

Hajiya Fatima Madugu, the Niger Commissioner for Education, Science, and Technology on Monday urged the Federal Government to adopt Nanotechnology in the development of science and technology sector.

Madugu, who made this known in an interview with the News Agency of Nigeria (NAN) in Minna, noted that Nanotechnology if adopted, would impact positively on industries and all spheres of the society.

She said that Nanotechnology was the application of extremely small things that could be applied across all fields of sciences such as chemistry, biology, physics, material science and engineering.

The technology will offer better built, long lasting, cleaner, safer and smarter products for the home, communication, medicine, transport, agriculture industry as well as the power sector.

Imagine a technology that can be used to deploy a medical device that travels through the human body to seek out and destroy small clusters of cancerous cells before they can spread.

This will be wonderful, she said.

According to her, understanding and utilising Nanotechnology will offer not only better products but vastly improved manufacturing process.

Nanotechnology is the next industrial revolution. It may be only a matter of time.

The real meaning of Nanotechnology will be clearly defined by the time building of products becomes cheap as the copying of files in a computer, she said.

Nanotechnology is the use of techniques and tools being developed today to make complete and high-performance products.

Printed solar cells thinner than your hair could power your phone – Phys.Org

Extremely thin printable solar panels could power your phone and are amongst a range of new ways nanotechnology is opening the door to a clean energy and waste-free future.

Nanotechnology, a science that focuses on understanding materials on an atomic scale, is helping researchers and businesses introduce new technologies that could transform our economy into a greener, less wasteful one.

“Nanotechnology as a field has an enormous role to play in moving our planet to sustainable and intelligent living,” said Professor Martin Curley from Maynooth University in Ireland, speaking on 21 June at the EuroNanoForum conference, in Malta, organised by the Maltese Presidency of the Council of the European Union and co-funded by the EU.

He explained to an audience of businesspeople and researchers that nanotechnology holds the potential to spark ‘an explosion of innovation”.

One area where this innovation could have its biggest impact is with how we generate, use and consume energy.

Speaking at a session dedicated to nanotechnology in clean energy generation, Prof. Alejandro Prez-Rodrguez, from the department of electronics at the University of Barcelona, Spain, said solar energy and photovoltaic (PV) technology itself could be considered a nanotechnology sector.

“In all PV technologies and devices we put some nanotechnology If we want to move to devices with higher functionality, lower weight, higher flexibility, different colours, then we need to integrate more nanotechnologies into their materials and architecture.”

At the same session, Artur Kupczunas, co-founder of Saule Technologies, explained how his company is using nanotechnology to print solar panels using perovskite crystals, a cheap and highly sensitive mineral that was first found in the Ural Mountains of Russia in 1839.

They produce thin layers of solar cells that are somewhere near one-tenth of the thickness of a single human hair. This innovation could greatly reduce the cost of producing solar energy while transforming any surface into a solar panel, from walls and road-side barriers to the surface of your smartphone.

“The most interesting factor is the (reduction of) overall costs,” said Kupczunas, explaining that this means the technology could be easily scaled out across the market.

Fuel cell

At the same session, John Bgild Hansen, a senior scientist from Haldor Topse, a Danish chemical engineering company, explained how they have been using nanotechnology to look at the atomic level of gases in order to better understand their properties.

This knowledge contributed to creating a fuel cell for greener biofuel production. Their process extracts pure hydrogen from plant materials while reusing any CO2 emissions created during the process to help power the production cycle, preventing any fossil fuels entering the atmosphere.

This, he believes, is a way to ‘break the bottleneck’ on biofuels which currently struggle to get public and private support.

“If we want the conveniences we have today from liquid energy carriers (oil, natural gas etc.) for transport hydrocarbons (biogas) are the best,” he said.

Storing wind and solar energy during unstable weather is another gap in our sustainable energy future.

Professor Magnus Bergen and his team at Sweden’s Linkping University are looking into using nanotechnology to harness the molecular properties of a plastic conductive material called PEDOT:PSS. They combine this knowledge with nanocellulose, a product made from plants or oil, to create an organic material that stores energy.

“If we make a (PEDOT:PSS) battery the size of a refrigerator it can store (enough energy for) the needs of a family in a house or an apartment for a day,” he said.

Because of its ability to charge quickly, it could be a way to compensate for the under- or over- production of wind and solar energy during calm or cloudy days. This, in turn, could break cities’ dependency on fossil fuels.

“You need to store when you are over-producing and release when you are under-producing,” Prof. Bergen explained.

Waste-free

Nanotechnology also has the ability to make technology smaller, extend the life-cycle of electronics, improve manufacturing processes, all of which would mean less waste has to go to the landfill.

Speaking at one of the sessions, Joe Murphy, from the Ellen MacArthur Foundation, an association in the UK dedicated to promoting waste as a resource, explained nanotechnologies ‘may enable us to create a new material palette’ that allows future products to be recycled more easily.

“At the moment we have a lot of barriers to recycling nanotechnology may enable us to do more,” he said.

Capturing Energy with Nanotechnology – AltEnergyMag (press release)

One goal of nanotechnology is to improve photovoltaic solar electricity generation. The thermodynamic limit of 80% productivity is well beyond the capabilities of current photovoltaic technologies, whose performance now is only about 43%.

Len Calderone for | AltEnergyMag

Can using nanotechnology in the efficient capture of sunlight and its conversion to electricity drive economical fuel production processes? Engineers at UC San Diego have developed a nanoparticle-based material for concentrating solar power plants that converts 90% of captured sunlight to heat. With particle sizes ranging from 10 nanometers to 10 micrometers, the multiscale structure traps and absorbs light more efficiently and at temperatures greater than 700 degrees Celsius.

The multiscale structures can catch and soak up light, which contributes to the material’s high proficiency when run at higher temperatures. This new market of concentrating solar power is an ideal alternative for clean energy. It can produce roughly 3.5 gigawatts of power, which is sufficient to power more than 2 million homes. Since it uses the same process as existing power plants, it can be used as a retrofit for existing power plants.

One of the most common types of concentrating solar power systems uses more than 100,000 reflective mirrors to direct sunlight at a tower that has been painted with a light absorbing material. The material is designed to maximize sun light absorption and minimize the loss of light.

A small type of concentrator can capture sun light for local usage. A luminescent solar concentrator is a sunlight harvesting technology that changes the way we think about energy. It could turn any window into a daytime power source. In these devices, a fraction of light transmitted through the window is absorbed by nanosized particles (semiconductor quantum dots) dispersed in a glass window. The light is then re-emitted at the infrared wavelength invisible to the human eye, and wave-guided to a solar cell at the edge of the window. With this process, a virtually transparent window becomes an electrical generator, one that can power a rooms air conditioner on a hot day or a heater on a cold one.

A solar harvesting system uses small organic molecules to absorb specific nonvisible wavelengths of sunlight. They can be tuned to pick up just the ultraviolet and the near infrared wavelengths that then glow at another wavelength in the infrared. The “glowing” infrared light is guided to the edge where it is converted to electricity by thin strips of photovoltaic solar cells. Because the materials do not absorb or emit light in the visible spectrum, they look transparent to the human eye.

This technology opens a variety of markets to deploy solar energy in a non-intrusive way. It can be used on sky scrapers with lots of windows, or any kind of mobile device that demands high visual quality like a smart phone.

Another use for integrated photovoltaics is the agriculture industry by utilizing existing structures as a base for which luminescent solar concentrators can be installed. A waveguide coupled with photovoltaic cells utilizes fluorescent dyes that convert light unused by plants in greenhouses to wavelengths suitable for photosynthesis. The dye absorbs incident light and readmits it isotopically. Light that is not emitted in the escape cone is guided through total internal reflection to front-facing photovoltaic cells, thus providing the necessary light for plant growth and generating energy to power the greenhouse.

Researchers have demonstrated that sunlight, concentrated on nanoparticles, can produce steam with high energy efficiency. The solar steam device is intended to be used in areas of developing countries without electricity for applications such as purifying water or sterilizing medical instruments. The new solar steam method is so effective it can even produce steam from ice-cold water. This technology is meant for small conversions and cannot be used for a solar plant to drive steam engines

The efficiency of solar steam is owed to the light-capturing nanoparticles that convert sunlight into heat. The particles are very smallsmaller than a wavelength of lightwhich means they have an extremely small surface area to dissipate heat. This intense heating generates steam locallyright at the surface of the particle.

When submerged in water and exposed to sunlight, the particles heat up so quickly that they instantly vaporize water and create steam. In ice water, the change to steam takes only 5 seconds. The nanoparticles convert 80% of the energy they absorb with carbon particles demonstrating greater efficiency than metal.

Lighting based on field-induced polymer electroluminescent technology gives off soft, white light in contrast to fluorescents and LEDs, which many people consider irritating. A nano-engineered polymer matrix is used to convert the charge into light. The technology allows the researchers to create an entirely new light bulb.

The new bulbs have the advantage of being shatterproof and twice as efficient than compact fluorescence light bulbs. Some researchers are developing high efficiency LED’s using collections of nano-sized structures called plasmonic cavities.

The light is made of three layers of moldable white-emitting polymer blended with a small number of nanomaterials that glow when stimulated to create bright and perfectly white light, similar to the sunlight human eyes prefer. It can also be made in any color and any shape. This new light is at least twice as efficient as compact fluorescent (CFL) bulbs and on par with LEDs, but these bulbs wont shatter and contaminate a home like CFLs or emit a bluish light like their LED counterparts.

Researchers have used sheets of nanotubes to build thermocells that generate electricity when the sides of the cell are at different temperatures. These nanotube sheets could be wrapped around hot pipes, such as the exhaust pipe of a car, to generate electricity from heat that is usually wasted.

Efficiently harvesting the thermal energy currently wasted in industrial plants or along pipelines could create local sources of clean energy that could be used to lower costs. The new thermocells use nanotube electrodes that provide a 3-times increase in energy conversion efficiency over conventional electrodes.

One of the thermocells looks just like the button cell batteries used in watches, calculators and other small electronics. The key difference is that these new thermocells can continuously generate electricity, instead of running down like a battery. Research can create other thermocells, including electrolyte-filled, textile-separated nanotube sheets that can be wrapped around pipes carrying hot waste streams of manufacturing or electrical power plants. The temperature difference between the pipe and its surroundings produces an electrochemical potential difference between the carbon nanotube sheets, which thermocells utilize to generate electricity.

Nanotube Thermocells Harvest Energy From Car Exhaust

One goal of nanotechnology is to improve photovoltaic solar electricity generation.The thermodynamic limit of 80% productivity is well beyond the capabilities of current photovoltaic technologies, whose performance now is only about 43%. A multidisciplinary, experimental and theoretical effort is now needed to make changes in the way solar cells are designed and manufactured. Nanotechnology provides a promising way to reach this goal with substantial increases in photovoltaic efficiency and cost reductions.
