Disclosed herein is a method of determining dopamine concentration at a target location in neural tissue. In several embodiments, the method comprises measuring current level in response to square wave voltammetry with a coated electrode of a neural probe implanted at the target location, wherein the coated electrode comprises a coating of poly 3,4 ethylene dioxythiophene (PEDOT) doped with negatively charged carbon nanotubes (CNT), and comparing the measured current level to a control current level to determine the dopamine concentration at the target location.
