Ultrabright Nanocrystals Could Image Single Proteins

Facebook X LinkedIn Email
The future is bright in the world of biological imaging with the recent creation of ultrabright, ultrasmall light-emitting crystals that can image single proteins. A team from the US Department of Energy’s Lawrence Berkeley National Laboratory developed the nanoprobes, which are less than 10 nm in diameter and could be especially effective for deep-tissue optical imaging of neurons in the brain. Using advanced single-particle characterization and theoretical modeling, the team has studied upconverting nanoparticles (UCNPs). Upconverted nanoparticles, created with nanocrystals...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.
