LUXEMBOURG, Sept. 3, 2020 — By coating droplets of an aqueous solution of hydroxpropyl cellulose with silica nanoparticles, and placing these “liquid marbles” inside an organic solvent, scientists have successfully made and displayed structural colors from cellulose-based polymers. Liquid marbles, which are millimeter-size droplets of liquid crystalline solutions, serve as a surrounding fluid in the system, and are coated to prevent them from mixing with the solvent. The marbles still interact with the fluid, however, producing colors in a process that yielded results that could be used as an...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.
