Abstract
A novel multifunctional nano-probe interface is proposed for applications in neural stimulation and detecting. The nano-probe interface structure consists of a carbon nanotube coated with a thin isolation layer, a micro-electrode substrate array, and a controller IC for neural cell recording and stimulation. The micro-electrode substrate array contains wires connecting the carbon nanotube with the controller IC, as well as microfluidic channels for supplying neural tissues with essential nutrition and medicine. The carbon nanotube is disposed on the micro-electrode substrate array made by silicon, coated with a thin isolation layer around thereof, and employed as a nano-probe for neural recording and stimulation.
