Nanotube Electrodes for Brain Implants
February 7, 2017 | Terry Sharrer
Most brain implants are made of metal wires, which can work but are not ideal. They can kill cells or puncture blood vessels and eventually draw immune cell responses. Researchers at Rice University, however, have made electrodes for brain implants out of carbon nanotubes—one inside another, with a channel for water to stiffen the structure after it is in place. Animal studies showed that the nanotubes had a longer functional period than metal wires. MORE
