“We want to find a single virus before it finds you,” says Charles Lieber, Hyman Professor of Chemistry at Harvard University. Tests recently completed in his laboratory show that these unimaginably thin nanowires can sense and distinguish between viruses that cause flu, measles, and eye infections. Lieber believes future versions will be able to spot HIV, Ebola, SARS, West Nile, hepatitis, bird flu, and other dangerous viruses. “Viruses are among the most important causes of human disease and are of increasing concern as agents for bioterrorism,” Lieber says. “Our work shows that nanoscale silicon wires can be configured as detectors that turn on or off in the presence of a single virus particle. Such detectors could be fashioned into arrays capable of sensing thousands of different viruses, ushering in a new era for diagnoses, biosafety, and quick response to viral outbreaks.”
