Scientists Get First Look At Nanotubes Inside Living Animals

Posted September 27, 2007 8:28 AM

From ScienceDaily Headlines:

Rice University scientists have captured the first optical images of carbon nanotubes inside a living organism. The researchers fed carbon nanotubes to newly hatched fruit flies. Using a laser, they excited a fluorescent glow from the nanotubes and took pictures of the near-infrared glow with a custom microscope. The researchers hope the technique will be useful in finding new ways to diagnose disease. "Carbon nanotubes are much smaller than living cells, and they give off fluorescent light in a way that researchers hope to harness to detect diseases earlier than currently possible," said research co-author Bruce Weisman, professor of chemistry. "In order to do that, we need to learn how to detect and monitor nanotubes inside living tissues, and we must also determine whether they pose any hazards to organisms."
