        Scientists Moungi Bawendi, Louis Brus and Alexei Ekimov won the 2023 Nobel Prize in Chemistry for "the discovery and synthesis of quantum dots," which illuminate computer monitors and television screens and are used by doctors to map tumours.
        
        "The Nobel Laureates ... have succeeded in producing particles so small that their properties are determined by quantum phenomena. The particles, which are called quantum dots, are now of great importance in nanotechnology," the Nobel Committee for Chemistry said in a statement.
        
        "Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and encrypted quantum communication." Nanoparticles and quantum dots are used in LED-lights and can also be used to guide surgeons while removing cancer tissue.
        
        The more than century-old prize is awarded by the Royal Swedish Academy of Sciences and is worth 11 million Swedish crowns ($997,959).
