New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA’s double helix. This finding has ramifications for gene therapy research and the emerging field of DNA-based electronics.

“We began this work with the goal of improving methods of packaging genetic material for use in gene therapy,” says Dr. Anatoli Melechko, an associate professor of materials science and engineering at NC State and co-author of a paper describing the research. Gene therapy is an approach for addressing certain medical conditions by modifying the DNA in relevant cells. (more…)

UCLA Team Develops Highly Efficient Method for Creating Flexible, Transparent Electrodes

As the market for liquid crystal displays and other electronics continues to drive up the price of indium — the material used to make the indium tin oxide (ITO) transparent electrodes in these devices — scientists have been searching for a less costly and more dynamic alternative, particularly for use in future flexible electronics.

Besides its high price, ITO has several drawbacks. It’s brittle, making it impractical for use in flexible displays and solar cells, and there is a lack of availability of indium, which is found primarily in Asia. Further, the production of ITO films is relatively inefficient. (more…)

*Undergraduate researcher Safatul Islam is a member of a team in the College of Optical Sciences investigating organic photovoltaics, which can lead to improved electronics.*

As the summer dwindles down, many people eagerly welcome the decline of long sunny days. But for others, this period of shorter days signals the end of the sun’s longest duration of generously giving energy to this region of the world.

Safatul Islam, a University of Arizona sophomore studying chemical engineering and mathematics, is working with researchers to develop better ways to harness the sun’s power for human use. (more…)

*MU scientists make strides in green nanotechnology*

COLUMBIA, Mo. – Gold nanoparticles, tiny pieces of gold so small that they can’t be seen by the naked eye, are used in electronics, healthcare products and as pharmaceuticals to fight cancer. Despite their positive uses, the process to make the nanoparticles requires dangerous and extremely toxic chemicals. While the nanotechnology industry is expected to produce large quantities of nanoparticles in the near future, researchers have been worried about the environmental impact of the global nanotechnological revolution.
