nanotubes may not be as toxic as previously reported elsewhere.\u00a0<!--more-->\u00a0Instead, contaminants mixed during the manufacture should be credited with the adverse health effects.\u00a0 According to Rockford Draper, a professor who worked on the study, &#8220;Carboxylated single-walled carbon nanotubes indeed reduce the ability of mammalian cells to grow in culture, but by using simple filtration methods we were able to remove the contaminants introduced during manufacturing.\u00a0 The resulting purified nanotubes were shown to have no ill effect on mammalian cells grown in culture.&#8221;\u00a0 Commercial manufacturers of nanotubes can immediately begin using the filtration process, and can then offer pre-screened purified nanotubes.\u00a0 Dan Herr, director of nanomanufacturing sciences at SRC, said, &#8220;During the manufacture of semiconductors using nanotubes, they are usually immobilized, preventing them from entering the environment.\u00a0 Nevertheless, we will continue to focus our efforts on minimizing their health impact and on insuring the safety of both the workers using these nanotube-based materials as well as on their potential hazards after manufacturing.&#8221;<\/p>\n<p>http:\/\/www.eetimes.com\/electronics-news\/4217099\/Carbon-nanotubes-not-toxic&#8211;researchers-say<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Research
