A neurosurgeon at the Methodist Neurological Institute (NI) is the first to use an enzyme-driven technique to label nanotubes with quantum dots, giving scientists a better way to see single-walled carbon nanotubes.
Dr. Baskin and Vladimir Didenko, PhD used an enzyme to create a permanent bond to attach semi-conductor nanocrystals, or Q-dots, to nanotubes. Because nanotubes absorb light, making them invisible, researchers have tried to find ways to make them visible inside living organisms. The light absorption properties of the nanotubes are bypassed by using the Q-dots.
