Liposome research meets nanotechnology to improve cancer treatment

In the race to find more effective ways to treat cancer, Boise State University biophysicist Daniel Fologea is working outside the rules of general mathematics that say one plus one equals two. In his world, one plus one adds up to a whole lot more.

While radiotherapy can precisely target just the tumor site, systemic chemotherapy spreads a wide net, sending drugs speeding throughout the entire body in an attempt to kill cancer cells while also killing many healthy cells. Neither of these methods is highly effective when applied alone, therefore separated sessions of chemo and radiotherapy are required when fighting against solid tumors.

Reports have shown that ideally, both methods would be employed at the same time. But doing so produces levels of toxicity that often are deadly. To reduce the remote toxicity inherent to chemotherapy, the drugs can be administered into solid tumors by using liposomes, which are nanoscale vesicles made from fats and loaded with anti-cancer drugs. Liposomes self-accumulate within the tumor but the loaded drugs will be released very slowly from their encasing.

A new patent awarded to Fologea, a professor in the Department of Physics, and co-researchers from the University of Arkansas in August 2014 holds promise of a way to combine the oomph of chemotherapy with the precision of radiotherapy, without harm to healthy cells.

In the new approach, said Fologea, "The liposomes are designed to release their precious cargo upon exposure to x-ray. Not only does this target where the medication goes, it also allows for a huge concentration of the drug to be released at once at the tumor site, thus increasing its efficacy. In addition, this combined modality of treatment employing concomitant radio and chemotherapy is supra-additive, which means it is several times more efficient than each therapy applied alone."

Here's how it works: liposomes have small scintillating nanoparticles embedded within them. When hit with the x-ray, they emit ultraviolet (UV) light. UV light triggers the release of Ca2+ entrapped into a photolabile cage inside the liposomes. The free Ca2+ activates an enzyme called phospholipase A2 that starts chewing the fats in the wall of the liposomes and triggers the fast release of the drug.

Now that they have a patent on the technique, researchers still expect several years of testing before the method is approved and available for cancer patients.

In the meantime, Fologea completed the initial phase of another method to provide similar results by using only materials previously approved by the FDA for treatment of cancer and other diseases. This approach will pave the way for earlier translational studies.

Working with Boise State biology professor Cheryl Jorcyk, he is looking for ways to put antibodies on the surface of the liposome, allowing them to recognize and attack cancer cells that are circulating in the body. A distinct approach to develop liposomes useful for treatment of diabetes is under development with Boise State biology professor Denise Wingett.

PETA Science Consortium experts to present at international nanotechnology workshop

PUBLIC RELEASE DATE:

12-Sep-2014

Contact: Tasgola Bruner TasgolaB@peta.org 404-907-4172 People for the Ethical Treatment of Animals

Washington, D.C. Experts from the PETA International Science Consortium will present strategies for optimizing nonanimal testing methods at a workshop that will examine the strengths and limitations of current alternatives to using animals to assess nanotoxicity.

Dr. Amy Clippinger, science advisor for the Science Consortium, will discuss exposure considerations that need to be addressed in order to optimize nonanimal testing strategies for human health risk assessment at the Nano Risk Analysis II Workshop in Washington, D.C. to be held September 15-16 at George Washington University's Milken Institute School of Public Health.

The Society for Risk Analysis organized the workshop to explore the way in which a multiple models approach can advance risk analysis of nanoscale materials. The workshop agenda includes presentations and panel discussions to inform the development of guidance for using these methods in a testing strategy to reduce and replace animal testing and to determine how they can be used in the risk analysis process.

The growing use of nanomaterials in consumer products has increased human exposure to these materials. Nanomaterials undergo many transformations between the time they are manufactured and the time humans are exposed, and thus it is critical to thoroughly characterize and test nanomaterials not only in their manufactured form but to examine them in the form that is most relevant to human exposure.

Says Dr. Clippinger, "It is important to understand the means by which humans may be exposed to a nanomaterial so that in vitro systems can be designed to mimic a realistic exposure. For example, in order to mimic the human situation, a material that is most likely to be inhaled would be coated in a physiologically relevant fluid, such as lung surfactant, and tested using human lung cells grown at the airliquid interface. Furthermore, it is critical to design testing strategies to incorporate in vitro methods in a risk assessmentbased paradigm that can be applied by regulators to make intelligent decisions regarding safety of nanomaterials."

Dr. Monita Sharma, nanotechnology expert for the Science Consortium, will also be a panelist for a discussion on applying nonanimal methods for human health risk assessment.

UT Arlington research uses nanotechnology to help cool electrons with no external sources

PUBLIC RELEASE DATE:

10-Sep-2014

Contact: Herb Booth hbooth@uta.edu 817-272-7075 University of Texas at Arlington @utarlington

A team of researchers has discovered a way to cool electrons to 228 C without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy.

The process involves passing electrons through a quantum well to cool them and keep them from heating.

The team details its research in "Energy-filtered cold electron transport at room temperature," which is published in Nature Communications on Wednesday, Sept. 10.

"We are the first to effectively cool electrons at room temperature. Researchers have done electron cooling before, but only when the entire device is immersed into an extremely cold cooling bath," said Seong Jin Koh, an associate professor at UT Arlington in the Materials Science & Engineering Department, who has led the research. "Obtaining cold electrons at room temperature has enormous technical benefits. For example, the requirement of using liquid helium or liquid nitrogen for cooling electrons in various electron systems can be lifted."

Electrons are thermally excited even at room temperature, which is a natural phenomenon. If that electron excitation could be suppressed, then the temperature of those electrons could be effectively lowered without external cooling, Koh said.

The team used a nanoscale structure which consists of a sequential array of a source electrode, a quantum well, a tunneling barrier, a quantum dot, another tunneling barrier, and a drain electrode to suppress electron excitation and to make electrons cold.

Cold electrons promise a new type of transistor that can operate at extremely low-energy consumption. "Implementing our findings to fabricating energy-efficient transistors is currently under way," Koh added.

Doped Graphene Nanoribbons with Potential

Contact Information

Available for logged-in reporters only

Newswise Graphene possesses many outstanding properties: it conducts heat and electricity, it is transparent, harder than diamond and extremely strong. But in order to use it to construct electronic switches, a material must not only be an outstanding conductor, it should also be switchable between on and off states. This requires the presence of a so-called bandgap, which enables semiconductors to be in an insulating state. The problem, however, is that the bandgap in graphene is extremely small. Empa researchers from the nanotech@surfaces laboratory thus developed a method some time ago to synthesise a form of graphene with larger bandgaps by allowing ultra-narrow graphene nanoribbons to grow via molecular self-assembly.

Graphene nanoribbons made of differently doped segments The researchers, led by Roman Fasel, have now achieved a new milestone by allowing graphene nanoribbons consisting of differently doped subsegments to grow. Instead of always using the same pure carbon molecules, they used additionally doped molecules molecules provided with foreign atoms in precisely defined positions, in this case nitrogen. By stringing together normal segments with nitrogen-doped segments on a gold (Au (111)) surface, so-called heterojunctions are created between the individual segments. The researchers have shown that these display similar properties to those of a classic p-n-junction, i.e. a junction featuring both positive and negative charges across different regions of the semiconductor crystal, thereby creating the basic structure allowing the development of many components used in the semiconductor industry. A p-n junction causes current to flow in only one direction. Because of the sharp transition at the heterojunction interface, the new structure also allows electron/hole pairs to be efficiently separated when an external voltage is applied, as demonstrated theoretically by theorists at Empa and collaborators at Rensselaer Polytechnic Institute The latter has a direct impact on the power yield of solar cells. The researchers describe the corresponding heterojunctions in segmented graphene nanoribbons in the recently published issue of Nature Nanotechnology.

Transferring graphene nanoribbons onto other substrates In addition, the scientists have solved another key issue for the integration of graphene nanotechnology into conventional semiconductor industry: how to transfer the ultra-narrow graphene ribbons onto another surface? As long as the graphene nanoribbons remain on a metal substrate (such as gold used here) they cannot be used as electronic switches. Gold conducts and thus creates a short-circuit that sabotages the appealing semiconducting properties of the graphene ribbon. Fasels team and colleagues at the Max-Planck-Institute for Polymer Research in Mainz have succeeded in showing that graphene nanoribbons can be transferred efficiently and intact using a relatively simple etching and cleaning process onto (virtually) any substrate, for example onto sapphire, calcium fluoride or silicon oxide.

Graphene is thus increasingly emerging as an interesting semiconductor material and a welcome addition to the omnipresent silicon. The semiconducting graphene nanoribbons are particularly attractive as they allow smaller and thus more energy efficient and faster electronic components than silicon. However, the generalized use of graphene nanoribbons in the electronics sector is not anticipated in the near future, due in part to scaling issues and in part to the difficulty of replacing well-established conventional silicon-based electronics. Fasel estimates that it may still take about 10 to 15 years before the first electronic switch made of graphene nanoribbons can be used in a product.

Graphene nanoribbons for photovoltaic components Photovoltaic components could also one day be based on graphene. In a second paper published in Nature Communications, Pascal Ruffieux also from the Empa nanotech@surfaces laboratory and his colleagues describe a possible use of graphene strips, for instance in solar cells. Ruffieux and his team have noticed that particularly narrow graphene nanoribbons absorb visible light exceptionally well and are therefore highly suitable for use as the absorber layer in organic solar cells. Compared to normal graphene, which absorbs light equally at all wavelengths, the light absorption in graphene nanoribbons can be increased enormously in a controlled way, whereby researchers set the width of the graphene nanoribbons with atomic precision.

nanotechnology noun na-n-tek-n-l-j

: the science of working with atoms and molecules to build devices (such as robots) that are extremely small

: the science of manipulating materials on an atomic or molecular scale especially to build microscopic devices (as robots)

nanotechnological -tek-n-l-ji-kl adjective

nanotechnologist -tek-n-l-jist noun

1974

Manipulation of atoms, molecules, and materials to form structures on the scale of nanometres (billionths of a metre). These nanostructures typically exhibit new properties or behaviours due to quantum mechanics. In 1959 Richard Feynman first pointed out some potential quantum benefits of miniaturization. A major advancement was the invention of molecular-beam epitaxy by Alfred Cho and John Arthur at Bell Laboratories in 1968 and its development in the 1970s, which enabled the controlled deposition of single atomic layers. Scientists have made some progress at building devices, including computer components, at nanoscales. Faster progress has occurred in the incorporation of nanomaterials in other products, such as stain-resistant coatings for clothes and invisible sunscreens.

Nanotechnology will leapfrog development

By Lalin Fernandopulle

Nanotechnology is the key to drive development and making Sri Lanka the Wonder of Asia, Senior Minister for Scientific Affairs Prof. Tissa Vitharana told a forum on Technology and Development : Can Nanotechnology leapfrog the Development Process in Sri Lanka organised by the Society for International Development last week.

He said that the secret of economic development in a country is technology. America achieved vast development due to its focus on science, technology and innovation.

The US President Barack Obama increased investments for science, technology and innovation by one percent of the GDP and it has paid rich dividends for the country today.

Many industrially developed countries achieved this feat because of its investments in science and technology.

Nanotechnology is the next level of development and if we are to keep pace with the growth in other countries by expanding our export income, we need to pay greater attention to developing niche products through nanotechnology, Prof. Vitharana said.

Panelists at the forum while commending the national initiative to develop nanotechnology through the nanotechnology park at the Sri Lanka Institute of Nano Technology in Homagama, said that there is much room for expanding the manufacture of nanotechnology based products such as garments and other utilities.

Sri Lanka is blessed with a diversity of resources which have not been adequately tapped for nanotechnoly development.

There has to be more focus and the industries should identify the potential of using nanotechnology to develop products, a panelist said.

Prof. Vithara drawing a parallel from South Korea which had a per capita GDP of around US$ 82 in the 1960s while Sri Lanka had a per capita income of US$ 320, said that South Korea's per capita income had increased to US$ 29,000 two years ago whereas in Sri Lanka it was only US$ 2,800.

Nanovations Will Showcase Their Nanotechnology Solutions for the Glass Industry at GlassBuild America 2014

Sydney, Australia and Las Vegas, NV, USA (PRWEB) August 28, 2014

Nanovations Pty Ltd will showcase its latest nanotech surface modifications for the glass industry in the Innovative Product Pavilion at GlassBuild America 2014 expo in Las Vegas, Nevada on September 9th 11th.

Visitors to the Nanovations Booth (#1144) will discover and experience the latest innovations in glass surface modification products, as well as other innovative product and service solutions that meet industry and customer needs. This will be the first time exhibiting at the GlassBuild America for the Australia-based manufacturer of innovative glass surface modifications and coatings. They will highlight several products with properties that have never been seen in America before.

Leading off Nanovationss product innovation display will be their NG-1010 and NG 1314 glass coatings. These products are formulated with an inorganic sol-gel technology developed exclusively by Nanovations. Unlike traditional soft glass coatings that cover the surface structure of the glass with a thin layer of non-stick chemicals, the Nanovations glass treatment follows the contours of the glass surface right down to the nanolevel with a hard inorganic layer. The technology creates water and dirt repellent effects on glass substrates that are both invisible and incredibly thin. These glass treatments are perfectly suited to a wide range of application: from facades and automotive windshields to shower screens and solar panels.

The use of such thin layers offers numerous advantages to the older alternatives. It allows for consumption rates that are up to twelve times lower lower than traditional coatings, as well as a high resistance to abrasion. The use of inorganic material also provides UV resistance, a necessary feature for the long term use of such coatings on external areas. NG 1314 offers additional scratch-resistance and reduction in dry dust reducing.

Nanovations will also launch the N-Bond UV Primer at the GlassBuild 2014. N-Bond is a new technology that promotes molecular adhesion and can be used for the bonding of organic materials to glass surfaces. The product was developed to promote the adhesion of UV curable inks such as those used in inkjets to glass surfaces. An adhesion promotion system is usually required to print high resolution images on glass surfaces, and the N-Bond technology offers molecular bonding without creating a film-like layer on the glass surface. The technology also offers fast printing times, cost effectiveness, and truly astronomical coverage rates.

We and our US representatives would like to welcome glass professional to visit us at our booth for further information, live demonstrations, or to find out how we can assist with a new revenue generation and cost saving leading edge technologies, said a company representative. Samples of the N-Bond and the automotive product Vision-Protects will also available in limited numbers.

GlassBuild America is the premier North American expo for the glass, window, and door industries, and will take place from September 9th to the 11th at the Las Vegas Convention Center in Las Vegas, Nevada.

About Nanovations Pty Ltd For fourteen years Nanovations Pty Ltd has been manufacturing innovative product solutions for problems that can appear on surfaces and materials used in the construction, industrial, automotive, and marine industries. They are the only Australian manufacturer of inorganic ultra-thin surface modifications and coatings for glass. As a part of their range of services, they promote environmentally responsible materials, methods, and practices. They help to incorporate the use of the latest technologies and products into sustainable building designs, and are currently the only carbon neutral nanotechnology company.

How Nanotechnology Is Gaining Momentum In Manufacturing

It is hard to imagine the size of a nanometer. At one-billionth of a meter, a nanometer has been compared to 1/80,000th the diameter of a human hair, a million times smaller than the length of an ant, or the amount a mans beard grows in the time it takes him to lift a razor to his face.

Yet, nanotechnologythe ability to control matter at the nanoscale (approximately 1 to 100 nanometers)is having a huge impact on science, engineering, and technology because matter behaves differently at that size.

The impact of nanotechnology on society has been compared to the invention of electricity or plasticit is transformative to nearly everything we use today. Uses of nanotechnology range from applications for stronger golf clubs and stain-resistant pants to future visions of transforming manufacturing and treating cancer.

Whats so special about nanotechnology?

Nanotechnology and nanoscience involve the ability to see and to control individual atoms and molecules. At nanoscale, matter has unique physical, chemical, and biological properties that enable new applications. Some nanostructured materials are stronger or have different magnetic properties; some are better at conducting heat or electricity, or may become more chemically reactive, reflect light better, or change color as their size or structure is altered.

According to an article in ASME.org, nanotechnology will leave virtually no aspect of life untouched and is expected to be in widespread use by 2020. In addition, a policy paper by the National Academy of Agricultural Sciences (NAAS) describes nanotechnology as modern historys sixth revolutionary technology, following the industrial revolution in the mid-1700s, nuclear energy revolution in the 1940s, green revolution in the 1960s, information technology revolution in the 1980s, and biotechnology revolution in the 1990s.

The U.S. federal government is backing nanotech, and the 2015 Federal Budget provides more than $1.5 billion for the National Nanotechnology Initiative (NNI),acontinued investment which supports the Presidents technology innovation strategy.

Recent investments in nanotech

Major investments in nanotech are being made at the state level and in the private sector as well. New York State recently partnered with General Electric and other New York-based companies on a $500 million initiative that will focus on the development of new, smaller semiconductors for computers and technology. These semiconductors are made possible by nanotechnology and are used in industries such as solar power, health care, and aviation.

The public-private partnership, known as the New York Power Electronics Manufacturing Consortium, will be based at the SUNY College of Nanoscale and Engineering in Albany but will involve companies and universities from around New York and is expected to create thousands of jobs. The use of the nanotech facility is also expected to attract researchers and private companies to create a high-tech cluster in New York State.
