New, all-graphene photodetector is both flexible and transparent

Researchers at the University of Exeter have developed a new photoelectric device that is both flexible and transparent. The device converts light into electrical signals by exploiting the unique properties of the recently discovered materials graphene and graphExeter. GraphExeter is the best known room temperature transparent conductor and graphene is the thinnest conductive material.

Food safety and bioterrorism defense may benefit from improved nanotechnology detection test

Sales of chicken products in China plummeted recently during an outbreak of a deadly new strain of bird flu. From bird flu to mad cow disease, numerous food scares have made global headlines in recent years. A technique developed by University of Missouri Professor of Engineering Shubhra Gangopadhyay's group may make food contamination testing more rapid and accurate. The detection test also could accelerate warnings after bioterrorism attacks.
