Are Carbon Nanotubes the Next Asbestos?
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.
