“The nanotubes are microscopic carbon cylinders, thousands of times smaller than a human hair that can be easily taken up by human cells,” said Elimelech. “We wanted to find out more about where and how they are toxic.”
This “nanoscience version of a David-and-Goliath story” was hailed in an ACS preview of the work as the first direct evidence that “carbon nanotubes have powerful antimicrobial activity, a discovery that could help fight the growing problem of antibiotic resistant infections.” Lisa Pfefferle.

Elimelech projects that SWCNTs could be used to create antimicrobial materials and surface coatings to improve hygiene, while their toxicity could be managed by embedding them to prevent their leaching into the environment. ###
