Light-Emission Studies May Improve Bioimaging

Facebook X LinkedIn Email
New understanding of secondary light emission by plasmonic nanostructures could lead to improvements in medical imaging. Work by materials scientists and engineers at the University of Illinois at Urbana-Champaign presents an alternate description of secondary light emission from plasmonic nanostructures, which is typically described as two-photon absorption followed by fluorescence, as a resonant electronic Raman scattering process. “Plasmonic nanostructures are of great current interest as chemical sensors, in vivo imaging agents and for photothermal therapeutics,”...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.
