noun

Physics
  • A nanoscale particle of semiconducting material that can be embedded in cells or organisms for various experimental purposes, such as labeling proteins.

    • ‘Since even a slight change in its properties can radically alter a quantum dot's performance, the control of properties often creates difficulties in device applications.’
    • ‘Chen and Gerion obtained a portion of this protein and attached it to the quantum dot.’
    • ‘When hit with light, the quantum dot emits a particular color based on its size.’
    • ‘In the new study, scientists applied voltage to the electron in a quantum dot, which is a tiny, nanometer-sized semiconductor.’
