Nanosphere-Laced Polymer Changes Color Under Stress

Facebook X LinkedIn Email
RIVERSIDE, Calif., May 23, 2014 — A plastic film that changes color under stress could provide more detailed information in product safety testing and other areas where pressure and strain are measured. A lab at the University of California, Riverside, used a self-assembly method to string together gold nanoparticles embedded in a polymer film. The system takes advantage of the plasmonic shift that results when nanoparticle chains are pulled apart. “When linked together, the gold nanoparticles originally appear blue,” said Yadong Yin, an associate professor of chemistry whose lab led the research....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.
