Carbon nanotube absorption measured in worms, cancer cells

with only about 0.5 percent of the nanotubes releases from the cell after 12 hours.

It's important to understand if and how the multi-walled carbon nanotubes accumulate in living cells, because before the materials can become widely used in society scientists must understand if they'll pass through the food webs and possibly threaten the health of ecosystems and lead to uptake by humans, Petersen said.

"This approach has virtually limitless potential for facilitating important future investigations of the behaviors of carbon nanotubes in environmental and biomedical applications," Petersen said.
