This year's Nobel Prize in Chemistry recognizes quantum dots, the tiny particles that light up television screens, LEDs, medical imaging and much more. Three scientists share the prize: Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov. Together, these scientists have shaped the future of nanoscience.
