Naturally glowing carbon nanotubes tracked in vivo
(Nanowerk News) Tracking nanomaterials in live organisms continues to be a tricky process for researchers searching for toxicological and environmental effects of these new materials. But a team of scientists found a way to take advantage of carbon nanotubes’ seemingly ready made tracking system, using their built-in reflectance characteristics to pinpoint the materials in live rabbits.
The researchers found no immediate adverse health effects and wrote that the nanotubes seem to have been evacuated from the animals’ blood and livers within an hour. However, many toxicologists studying nanomaterials say that much more work remains to be done before they are proven safe.
