Physicians and public health officials may no longer have to choose between flu tests that are accurate yet time-consuming or rapid but error-prone, thanks to a new detection method that can identify influenza in minutes at only a fraction of a penny per exam. A new test from the University of Georgia now offers the best of both worlds. By coating gold nanoparticles with antibodies that bind to specific strains of the flu virus and measuring how the particles scatter laser light, the technology can detect influenza at the point of patient care. “We routinely survey the...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
