Research opens doors to UV disinfection using LED technology

Research from North Carolina State University will allow the development of energy-efficient LED devices that use ultraviolet (UV) light to kill pathogens such as bacteria and viruses. The technology has a wide array of applications ranging from drinking-water treatment to sterilizing surgical tools.

You can't play nano-billiards on a bumpy table

There's nothing worse than a shonky pool table with an unseen groove or bump that sends your shot off course: a new study has found that the same goes at the nano-scale, where the "billiard balls" are tiny electrons moving across a "table" made of the semiconductor gallium arsenide.

New ultra-thin electronic films have greater capacity

The development of a new combination of polymers associating sugars with oil-based macromolecules makes it possible to design ultra-thin films capable of self-organization with a 5-nanometer resolution. This opens up new horizons for increasing the capacity of hard discs and the speed of microprocessors.

Plasmonic nanobubbles plus chemotherapy equals single-cell cancer targeting

Using light-harvesting nanoparticles to convert laser energy into "plasmonic nanobubbles", researchers are developing new methods to inject drugs and genetic payloads directly into cancer cells. In tests on drug-resistant cancer cells, the researchers found that delivering chemotherapy drugs with nanobubbles was up to 30 times more deadly to cancer cells than traditional drug treatment and required less than one-tenth the clinical dose.
