Scientists find nanowires capable of detecting individual viruses

Published in TB and Outbreaks Week, October 12th, 2004

Harvard University scientists have found that ultra-thin silicon wires can be used to electrically detect the presence of single viruses, in real time, with near-perfect selectivity.

These nanowire 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.

The work was reported online September 13, 2004, in Proceedings of the National Academy of Sciences.

"Viruses are among the most important causes of human disease and are of increasing concern as possible agents of biowarfare and...
