This Is Your Brain on Nanotubes

Carbon nanotubes — incredibly strong, electrically conductive, hollow molecules of carbon about a nanometer in diameter — have for more than a decade been prized by materials scientists. They’ve added them to batteries to increase their surface area and are developing light-emitting nanotubes for telecommunications. Now University of Texas researchers have demonstrated that mats of single-walled carbon nanotubes can communicate electrical signals to neurons, suggesting that the tubes could be used as an electrical interface between neural prosthetics — devices used to replace damaged or missing nerves — and the body. This is good news for those hoping to use nanotubes to stimulate or replace nerve cells in the eye, brain, and spinal cord.
