Nanodevices target viruses

Abstract:
Physicists are used to detecting inanimate objects like photons and particles but two teams of researchers in the US have now turned their attention to very different targets -- viruses. Harold Craighead and colleagues at Cornell University used a nanoelectromechanical device to detect an insect baculovirus, while Charles Lieber and co-workers at Harvard University employed a nanowire field-effect transistor to detect single influenza viruses. The new methods could be scaled up for applications in medicine or the detection of biological weapons.
