Nanodevices target viruses

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.
