Learning from History: Understanding the Carcinogenic Risks of Nanotechnology
| The first 10% of the full text of this article appears below. |
Smaller than the average microscope can see, nanomaterials have been used in commercial products to improve industrial design and marketability for the past several years. Titanium oxide nanoparticles in sunscreen block ultraviolet rays yet allow for smooth application of the lotion and absorption into the skin. Carbon nanotubes in bicycle frames and tennis rackets make them stronger and lighter. Researchers are also using nanoparticles to direct cancer drugs to tumor tissue both in the lab and the clinic. But with these advances, some researchers have noted that the public and environmental health effects of manufacturing these materials are still unclear.
"This is not an issue to cause alarm," said
