Cancer and Carbon Nanotubes - Method for Treating Cancer using Nanotechnology
Hongjie Dai is a chemist at Stanford University. He and his team of researchers
have developed a method for treating cancer using carbon nanotubes, synthetic
rods so tiny that thousands could fit in a single cell. The team coats carbon
nanotubes in the B-vitamin folate. In that way they can fit the nanotubes to
the numerous folate receptors present on cancer cells.
An interesting property of carbon nanotubes is that they absorb near-infrared
radiation. This causes them to heat up very quickly. Once the nanotube is attached
to the cancer cells, Dai uses a near-infrared laser beam to heat the nanotubes
until they kill the cancer cells.
The method is still at a very early stage of testing. It will likely be two
or more years before it is tested in clinical trials with human patients.
