Disproportionation During Electrooxidation of Catecholamines at Carbon-Fiber Microelectrodes

A study examined the effect of following chemical reactions during chrono-amperometry and cyclic voltammetry at microelectrodes. Evidence shows that for most applications of carbon-fiber microelectrodes as sensors of catecholamine secretion from cells, the effect of the DISP1 reaction can be ignored...
