Gold nanograin microelectrodes for neuroelectronic interfaces.
Raeyoung Kim, Nari Hong and Yoonkey Nam*
This work reported a design of microelectrodes using gold nanostructures ('nanograin') for neural recording and stimulation. We developed a electrochemical deposition technique to generate a nanograin structures on metal microelectrodes and characterized metal-electrolyte interfaces using AC impedance spectroscopy and current injection tests.
