nanotechnology

North Carolina State University researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin, a ubiquitous substance found in all plant cells. The findings introduce ideas for better, greener and safer nanotechnology and could lead to enhanced efficiency of antimicrobial products used in agriculture and personal care.

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering have designed a nanoparticle transport system for gene delivery that destroys deadly brain gliomas in a rat model, significantly extending the lives of the treated animals. The nanoparticles are filled with genes for an enzyme that converts a prodrug called ganciclovir into a potent destroyer of the glioma cells.

Sometimes looking at something at the smallest scale can lead to solutions to big problems.

A quantum mechanical transport phenomenon demonstrated for the first time in synthetic, atomically-thin layered material at room temperature could lead to novel nanoelectronic circuits and devices, according to researchers at Penn State and three other U.S. and international universities.

Researchers have solved the long-standing conundrum of how the boundary between grains of graphene affects heat conductivity in thin films of the miracle substance — bringing developers a step closer to being able to engineer films at a scale useful for cooling microelectronic devices and hundreds of other nano-tech applications.

Origami, the Japanese art of paper folding, can be used to create beautiful birds, frogs and other small sculptures. Now a Binghamton University engineer says the technique can be applied to building batteries, too.

Scientists around the world are using the programmability of DNA to assemble complex nanometer-scale structures. Until now, however, production of these artificial structures has been limited to water-based environments, because DNA naturally functions inside the watery environment of living cells.
