Electrical Detection of Single Viruses

Harvard University scientists have found that nanowire field effect transistors can be used to electrically detect the presence of single viruses in real time, with near-perfect selectivity.
These detectors can also differentiate among viruses with great precision, suggesting that the technique could be scaled up to create miniature arrays easily capable of sensing thousands of different viruses.
