Light triggers biochemical reactions

Ashley N. Rice, [email protected]

Biochemical reactions can now be remotely triggered on demand, thanks to a new technique that turns light into heat at the point of need on the nanoscale. The method, created by Rice University researchers, uses materials derived from unique deep-sea microbes called thermophiles, which thrive at high temperatures but which shut down at room temperature. When enzymes from the microbes are combined with plasmonic gold nanoparticles that heat up when exposed to near-infrared light, the enzymes activate and carry out their functions. This effectively allows chemical processes to...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.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
