An integrated, tip-shaped micro array sensor with counter electrodes, an electrochemically deposited Ag/AgCl reference electrode and a dopamine sensing working electrode covered with an antifouling film of conducting polymer has been realized. Using for the first time an electrochemically deposited coating consisting of a composite of poly(1,4-ethylenedioxythiophene)/carbon nanotubes/surfactants on a Pt microelectrode surface, dopamine concentrations as low as 200 nM could be measured with differential pulse voltammetry.
