Characterization of Novel Microelectrode Geometries for Detection of Neurotransmitters

In this paper, a microelectrode array is introduced and characterized using differential pulse voltammetry (DPV), amperometry and fast scan cyclic voltammetry with norepinephrine as a model neurotransmitter. Twenty-one sensor geometries were evaluated with DPV to determine optimal electrode configurations. Next, electrode responses were characterized for the best electrode geometry using an onboard platinum pseudo-reference electrode, whose reliability is established.
