Medical Journal - Houston (Internet / Print) May 2006 http://www.mjhnews.com/mjh_pg09.htm Texas scientists have added one more trick to the amazing repertoire of carbon nanotubes – the ability to carry electrical signals to nerve cells. Thin films of carbon nanotubes deposited on transparent plastic can serve as a surface on which cells can grow. And as researchers at the University of Texas Medical Branch at Galveston (UTMB) and Rice University suggest in a paper published in the May issue of the Journal of Nanoscience and Nanotechnology, these nanotube films could potentially serve as an electrical interface between living tissue and prosthetic devices or biomedical instruments. “As far as I know, we’re the first group to show that you can have some kind of electrical communication between these two things, by stimulating cells through our transparent conductive layer,” said Todd Pappas, director of sensory and molecular neuroengineering at UTMB’s Center for Biomedical Engineering and one of the study’s authors.
