Abstract

The application of gold nanowire arrays for neuronal recording and stimulation is explored. The process of electrochemical anodization is utilized to grow an aluminum oxide template consisting of an array of closely packed cylindrical pores with diameters in the range of nanometers and micron scale depth. The method of electrodeposition is used to deposit gold within the pores forming a nanowire array. By means of micro and nanoscale fabrication processes, this array is integrated at one end with microscale gold electrodes. At the other end, neuron cells are cultured. Such nanowire-array structures will eventually be used to record and stimulate neuronal activity.
