Nanotechnology is the catch-all term used to describe, in short, science and engineering on an insanely small scale. Carbon nanotubes one of the more common nanoscale structures in use today are long, thin cylinders of carbon roughly 10,000 times smaller than the width of a human hair.

These molecular scale tubes are stronger than steel yet lighter than aluminum and today, they are being developed for use in a variety of consumer products. But under a microscope, CNTs look identical to asbestos fibers, leading scientists to believe that they could cause similar health problems. In this video we traveled to North Carolina State University to meet Dr. Jamie Bonner to learn more about his research on the potential toxicity of carbon nanotubes.
