A fast and inexpensive nanotube device to capture and identify viruses

Researchers at Penn State and New York University have developed a device to quickly capture and identify various strains of viruses. The device uses arrays of nanotubes that capture different viruses according to their size and uses Raman spectroscopy to identify the viruses based on their individual vibrations. Because of its size and cheapness, such a device could be useful in a doctor’s office and in locations where disease outbreaks occur.
