It sounds like a wonderful dream, but UltraTech's coating being tested on cars can repel water, dirt, and oil, cutting down on the number of trips you have to take to the car wash.

NISSAN This Nissan Versa Note would normally require a lot of scrubbing down after a muddy drive like this, but the carmaker and UltraTech are testingUltra-Ever Dry coating on vehicles to see how it repels water, dirt, and mud.

Not many people would confuse the sporty Nissan Versa Note with a commercial cement truck, but the two vehicles could have something in common one day: Special nano-coating that prevents water, dirt, fine oils, and even wet concrete from sticking to the car's surface. This new self-cleaning superhydrophobic technology may not entirely eliminate trips to the car wash, but it could mean that you'll go a year between visits.

Nissan engineers are testing UltraTech's Ultra-Ever Dry coating on a Nissan Versa Note at Nissan Technical Centre Europe under many conditions. Ultra-Ever Dry protects the Nissan from rain, spray, frost, sleet, and standing water. Ultra-Ever Dry may become an aftermarket option for the carmaker.

Ultra-Ever Dry has been a great help to the construction industry where it's being used to coat cement trucks, making them much easier to clean, says Mario Cruz, UltraTech's marketing manager.

In testing, UltraTech and Nissan are using a white car because Ultra-Ever Dry is opaque and "whitish translucent," according to Cruz. The coating doesn't have a glossy shine like the one left after hours with a can of wax and a chamois because the finish appears matte flat.

A surface treated with Ultra-Every Dry is more hydrophobic than wax or even water-resistant windshield coating, so it better repels water. The Ultra-Ever Dry coating will only last for about a year before it will have to re-applied depending upon weather conditions. Don't expect to use it on tires or upholstery, Cruz says: "It will wear off from abrasion."

UltraTech CEO Mark Shaw showed off the coating technology during a 2013 TED Talk. Nanoparticles coat the surface making a texture with patterns of geometric shapes that have "peaks" or "high points". These teeny-tiny high points repel water, some oils, wet concrete, and other liquids.

If you're thinking you'd love some Ultra-Ever Dry for your car, kitchen floor, snow shovel, kennel or garage, you're out of luck--it's only available for industrial use at this point. Cruz says that only a professional with the right equipment can apply the material to surfaces.

Newswise Troy, N.Y. Xing Wang, a biochemist investigating the bio-nanotechnology potential of DNA and RNA, has been appointed as an assistant professor in the Department of Chemistry and Chemical Biology at Rensselaer Polytechnic Institute. Wang joins Rensselaer from the University of South Florida, where he served as an assistant professor.

Xings research offers broad promise in drug delivery, bio-imaging, as a platform for research, and for other therapeutics and diagnostics, said Laurie Leshin, dean of the School of Science. We are thrilled he is joining the School of Science, and we welcome him to Rensselaer.

DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are familiar to us as the molecules that encode and transcribe the genetic instructions for building and sustaining all living organisms. Both DNA and RNA are composed of simple units called nucleotides that function as modular units, strung together in a genetic code much as dots and dashes are strung together in Morse code. Wangs research seeks to repurpose the modular nucleotides as building blocks for self-assembled nanoscale (one billionth of meter) structures and machinery.

DNA and RNA have a lot of advantages as bio-nanotechnology materials, said Wang. Among the advantages, DNA and RNA are bio-compatible, they can be readily synthesized or cloned, the rules that govern the interactions between nucleotides are highly predictable, and chemical properties of nucleotides are easily modified using current lab techniques.

In previous research, Wang investigated programming sequences of DNA strands that can self-assemble into two- or three-dimensional structures.

You can draw something on paper, a two- or three-dimensional structure, and then you can program sequences of DNA strands that will form your design, said Wang. Currently, this design process can even be assisted by semi-automated computer programs.

Self-assembled DNA nanostructure can serve as a prototyping breadboard to study the interactions of elements such as proteins, drugs, nanoparticles, or semiconducting quantum dots attached to the platform. A similar platform might serve as a sort of circuit board for nanoparticles aligned to form an electrical device. DNA might also be used in a drug delivery system, designed to enclose and protect a drug as it travels in the body, and bind to molecular receptors found only on the drug target.

Wang also researches RNA, which uses a slightly different set of nucleotides. Interactions among RNA chains are more complex than those among DNA chains.

The cosmetic industry is one of the most competitive in the world, that is why is noteworthy that a Mexican development is part of one of the most pervasive innovations in recent years. It is the application of nanoparticles of titanium dioxide (TiO2) as sunscreens.

The contribution is the result of research and development by "Nanomateriales", a Mexican enterprise in the north of the country, led by scientist Joel Antonio Gutierrez, who said that the products are already sold in Mexico, USA and South America.

The Mexican firm is responsible for developing nanotechnology solutions for various sectors, meaning that their research does not focus on a single article, but in applications that give added value to different products, and thus provide customers with a more competitive and diverse market.

For example, the company developed a cosmetic sunscreen based in titanium dioxide nanoparticles, which can reduce the effects of UVA/UVB rays, related to skin deterioration.

The innovation for the titanium dioxide product was to develop a technique to disperse the particles (five to 10 nanometers in size) to avoid agglomeration.

A high-tech dispersion physicochemical process was designed, which will ensure that the nanoparticles remain stable in the formulation of the final product. The advantage in the cosmetic formula is that using titanium dioxide nanoparticles increases the photo protective efficacy, since it has been demonstrated that the lower the particle size the better the protective UV efficiency.

In addition to the cosmetic industry, the company seeks to implement the nanoparticles on other products, such as waterproofing paints, coatings and plastics, because it improves resistance to environmental exposure. However, so far it has only been marketed in sunscreens.

For Antonio Gutirrez, the commitment to nanotechnology is because it represents over 50 billion dollars in the worldwide market, therefore he expects "Nanomateriales" to continue with developments for various sectors including aerospace and information technology where applications for spacecraft and processors are being prepared.

The Mexican company has four years in operation, despite his young age it has managed to introduce its products in international markets, such as USA, Canada and South America. However, the director tells us that his success has not been easy. "This industry, like few others, requires highly skilled and specific technology for its production," he says.

Barbara Herr Harthorn

A Q&A with Barbara Harthorn, Head of UCSBs Center for Nanotechnology inSociety

As the head of UCSBs Center for Nanotechnology in Society (CNS), Barbara Harthorn has spent the past eight-plus years leading a team of researchers in studying peoples perceptions of the small-scale science with big-scale implications. Sponsored by the National Science Foundation, CNS enjoys national and worldwide recognition for the social science lens it holds up to physical and lifesciences.

For some perspective, a nanometer clocks in at about one-billionth of a meter and the thickness of a piece of paper is a whopping 100,000 nanometers. As tiny as the units are, their applications are growing increasinglypopular.

Earlier this year, Harthorn attended a meeting hosted by the Presidential Commission for the Study of Bioethical Issues. The commissions chief focus was on the intersection of ethics and brain research, but Harthorn was invited to share her thoughts on the relationship between ethics and nanotechnology. A few days after her testimony, Harthorn who also teaches anthropology at UCSB spoke with The Santa Barbara Independent about what opportunities nanotechnology pushes forward and what challenges it creates in making sure those opportunities dont cross the ethical line. Below is an edited version of ourconversation.

What are some common uses of manufactured nanomaterials? In the health industry, there is a huge array of applications, including cosmetics, skin products, and sunscreens. CNS started in January 2006; at that point, the largest number of patents in the world was held by LOreal. The nanoscale forms of metal oxides have different optical properties, making them very attractive for use incosmetics.

In what other areas are they commonly found? The automotive industry has a bunch of implications, as does the aerospace industry. Theyre using them in building materials. There are nano-additives for concrete to make concrete stronger. There is controversy about nano-silver bulk silver is an anti-microbial so people are using nano forms of silver as an anti-bacterial coating. It is being used in hospitals, offering the promise of potentially killing current drug-resistant forms of bacteria. But they are very powerful, and there is a lot of concern about the potential for generating new super-bugs, if usedhaphazardly.

At CNS, we have looked at the global chain of teddy bears that have [nano-silver particles]. They are spread onto the surface of the teddy bear that is presumably for use by an infant and conveys the whole idea of super safety but super hazard. Samsung put it in washing machines, which produced a regulatory action, and Samsung had to treat it as a pesticide. If you buy anti-microbial socks, those could have nano-silver particles. There arent a lot of reasons to think there is harm of [skin transfer] by the person wearing the socks but when you wash the socks, the particles arent bound into the textile in a chemical way and can go down the drain and enter the water treatmentsystem.

So there are some environmental concerns with nanomaterials. What are the ethical concerns? What came across at the Presidential Commission meeting? Theyre talking about treatment of Alzheimers and neurological brain disorders, where the issue of loss of self is a fairly integral part of the disease. There are complicated issues about patients decision-making. Nanomaterials could be used to grow new tissues and potentially new organs in thefuture.

Salvador, Brazil Despite nanotechnology's huge potential to alleviate poverty, it is one of the least covered science topics in Nigerian newspapers, a study finds.

The study, which is yet to be published, was presented by Herbert Batta, a communication lecturer at Nigeria's University of Uyo, at the 13th International Public Communication of Science and Technology conference (PCST2014) in Brazil, this week (5-8 May).

"This may indicate the lack of knowledge among journalists in that area, and an underdeveloped state of that science in the country, or the difficulties experienced in the science-journalism interface," it says.

The study analysed the science coverage of three national newspapers, The Guardian, Daily Trust and Leadership, in 2012.

The study found little difference between the papers' coverage of nanoscience and nanotechnology issues, with these subjects being covered by only 3.6 per cent of The Guardian's science articles, just over one per cent of those in the Leadership and none in the Daily Trust.

In all, the three papers produced 329 individual science stories in 2012. The most frequent topics covered by The Guardian were related to health, in the Leadership it was stories on robotics, biotechnology and information and communications technology, while in the Daily Trust nearly all science articles were about health and medicine.

Batta said: "Nanoscience and nanotechnology can be used to solve problems ranging from the provision of healthcare, especially for chronic diseases such as HIV/AIDS, water purification and the supply of clean energy, but the media hardly covers them." This means those in the newspapers' audience who could make use of them are unaware of their possible benefits, he added.

Batta said there are few nanotechnology experts in Nigeria and in Africa more generally. The few there are in Nigeria often work at institutions that are not active in raising awareness among the public about nanoscience and nanotechnology.

Nanotechnology is still an emerging area of science in Africa, in which there has been modest progress, he said. "Scientists involved also seem fearful of engaging with the media without [having] any breakthroughs [to report]," he added.

According to Batta, science journalists' associations and nanotechnology scientists could work to bridge the gap by organising events to help the media understand the subject.

Nigeria: Nigerian newspapers hardly cover nanotechnology

Computerworld - In a second report this week on scientists' use of nanotechnology to battle cancer, researchers at MIT announced a new way to use nanoparticles to give cancerous cells a one-two punch.

MIT reported that researchers used nanoparticles to carry two drugs and release them one at a time. The treatment was shown to "dramatically shrink" lung and breast tumors in mice.

"I think it's a harbinger of what nanomedicine can do for us in the future," said Paula Hammond, an MIT professor of engineering, in a statement. "We're moving from the simplest model of the nanoparticle -- just getting the drug in there and targeting it -- to having smart nanoparticles that deliver drug combinations in the way that you need to really attack the tumor."

The university explained that first the nanoparticles disarm the cancer cell's defenses by releasing a drug called Erlotinib, also known as Tarceva, which shuts down one of the pathways that promote uncontrolled tumor growth. Then the nanoparticles release another drug called Doxorubicin, also known as Adriamycin.

Once weakened by the administering of the Erlotinib, the cancer cells are more susceptible to being treated with the second drug.

"It's like rewiring a circuit," said Michael Yaffe, an MIT professor. "When you give the first drug, the wires' connections get switched around so that the second drug works in a much more effective way."

Scientists have known that treating cancer patients with the prolonged attack of two or more drugs can bring greater success than using one medication. In more recent years, they've also determined that the specific timing of the drug delivery has a significant affect on the outcome.

According to MIT, using Erlotinib and Doxorubicin in a specifically timed succession proved a powerful tool to beat back a specific type of breast cancer known as triple-negative tumors, an aggressive cancer that tends to strike young women.

To deliver these drugs, the scientists turned to nanotechnology.

The researchers designed the nanoparticle so that the Erlotinib is embedded in the outer layer of it, while Doxorubicin is inside the particle's core. The particles are coated with a polymer, protecting them from breaking down in the body or being filtered out by the liver and kidneys.

MIT uses nanotech to hit cancer with one-two punch

The eye-strain implications alone are staggering.

To promote the upcoming Exceptional Hardware Software Meeting (EHSM) in Hamburg, Germany, a team of DIY artists and scientists has etched the worlds smallest comic strip on a single human hair.

PHOTOS: Dazzling OMG Microscope

Titled Juana Knits The Planet, the strip was created by German artist Claudia Puhlfurst, then carved into the hair using a process called focused ion beam (FIB) etching. A very sharp and high-speed jet of matter is produced and directed towards the hair to etch it similar to a fine laser beam, according to the projects YouTube page.

Each of the strips 12 frames measures in at around 25 micrometers. A micrometer, or micron, is one millionth of a meter. A typical human hair is anywhere from 20 to 200 microns in width.

NEWS: Worlds Smallest Image Nano-Chiseled from Polymer

The second annual EHSM event bills itself as a meeting of international makers, hackers, scientists and engineers aiming to deliver on the third industrial revolution. The rest of the conference looks pretty trippy, too.

Among the presentations: electron beam welding, quantum cryptography and the interesting things that happen when molten glass, heated to 1,260 degrees Celcius, hits water. Ive always been curious about that.

Orlando, FL (PRWEB) May 08, 2014

At a hearing held January of 2014, the Court questioned Declinols scientific expert on Declinols use of the term nanotechnology, stating, in fact, your use of the term nanotechnology, its a bit of a stretch, isnt it? The court went further, asking wouldnt it be more accurate to call it liposomal delivery? Declinols own scientific witness agreed with the Court. (source 6)

With the denial of the motion brought by Kirven, Declinol and Puricorp, Avantcares case against Kirven, Declinol, and Puricorp for intellectual property infringement, false advertising, and deceptive trade practices is clear to proceed in Federal Court. (source 5)

Nanotechnology is a questionable technology that works with atoms in the process of manipulating matter at the molecular level. Puricorp had maintained that the use of nanotechnology in their products was not dangerous to human health but recently removed references to nanotechnology in their advertising for one of their products.

Dr. Frank W. Gibson, creator of the Last Call Program and Sobrexa and Avantcare, Inc. CEO, reported that the Companys Science and Medical Board carefully studied the dangers of nanotechnology prior to declaring nanotech products unsafe and pledging never to use nanotechnology in any of the Companys products. As the leader in the field of addiction and natural products, we looked at nanotechnology very closely with some scary results. The fact that nanotech disables the bodys natural ability to protect itself from harmful particles and that nano particles have the potential to bypass the blood brain barrier and remain in the brain and organs for much longer than normally sized particles (source 1) was enough for us to join the world-wide stand against nanotechnology. The fact that a new, untested and un-regulated technology has been introduced into the marketplace is of real concern. We take our responsibility to protect and inform our consumers very seriously.

According to a study in the Journal of Nanoscience and Nanotechnology, nanomaterials may, enter the body through the lungs or other organs via food, drink, and medicine and affect different organs and tissues such as the brain, liver, kidney, heart, colon, spleen, bone, blood, etc. and may cause cytotoxic effects, e.g. deformation and inhibition of cell growth leading to various diseases in humans and animals. (source 2,3)

The FDA currently has little regulatory authority over nanoengineered products, but the agency states that it is a top priority. In the April 2012 FDA Nanotechnology Fact Sheet, the FDA states: Understanding nanotechnology remains a top FDA priority. FDA is monitoring the evolving science and has a robust research agenda to help assess the safety and effectiveness of products using nanotechnology. (source 4)
