The 2024 Kavli Prize in Nanoscience honors Robert Langer, Paul Alivisatos and Chad Mirkin who each revolutionized the field of nanomedicine by demonstrating how engineering nanoscale materials can advance biomedical research and application. Armand Paul Alivisatos demonstrated that semiconductor nanocrystals, or quantum dots (nanoparticles that possess bright, size-dependent light-emitting properties), can be used as multicolor probes in bioimaging. Essential to this achievement was the synthesis of biocompatible nanocrystals. Semiconductor nanocrystals became the basis for the widely used research and diagnostic tools such as live cell tracking, labelling and in vivo imaging.
