Electro-synthesized PEDOT/glutamate chemically modified electrode: a combination of electrical and biocompatible features

Abstract

BACKGROUND: Neural prosthetic devices have been developed that can facilitate the stimulation and recording of electrical activity when implanted in the central nervous system. The key parts of the devices are metal (gold) electrodes; however, surface modification of the gold electrode is desired. Conducting polymers are promising candidates for this purpose. RESULTS: A conducting polymer, poly(3,4‐ethylenedioxythiophene) (PEDOT), was electro‐polymerized onto gold electrodes with a neural transmitter of glutam…
