Scientists at Oak Ridge National Laboratory have used in situ time-lapse photography and laser irradiation to watch and record the growth of carbon nanotubes. Laser irradiation of the growing nanotubes help prove that the nanotubes grow from catalyst particles at their bases. Researchers are interested in finding ways to grow the longest tubes in the fastest amount of time while still maintaining good nanotube quality. Irradiating the nanotubes with a laser during growth has also been shown to increase the growth rate of the arrays.

Why are carbon nanotubes so interesting? They can be used to make things lighter and stronger, build space elevators, and even combat cancer!
