Quantum dots are semiconductor nanoparticles that confine electrons and holes in all three dimensions. They are made using different methods like lithography, colloidal synthesis, or epitaxy. Quantum dots have discrete energy levels that depend on their size and shape. They have potential applications in solar cells, LEDs, bioimaging, drug delivery, and anti-counterfeiting due to their tunable light emission properties.

- 24. . These quantum dots can be put into single cells, or lots of cells, in the tissue of living organisms. In future, it is planned to attach specific antibodies to the quantum dots – when injected into a body, the quantum dots will find and bind to cancer cells, and illuminate them when they fluoresce.

Editor's Notes
- Quantum dots created on the surface of GaAs in selective MOCVD growth ( metallorganic vapor phase epitaxy) ; width of the electron localization area at the top of the pyramid is about 100 nm.
