Semiconductor nanocrystals are clusters of atoms about 10 nanometers or smaller that glow different colors depending on their size. Biophysicist Jeeseong Hwang holds a solution of red nanocrystals used to identify specific biomolecules. Hwang and his colleagues are measuring the optical properties of single nanocrystals to help medical researchers better calibrate tests using this new nanotechnology.
