Dopamine and Ascorbate Analysis and Fallowing Reaction Kinetics with Hydrodynamic Diamond Electrodes

摘要

Dopamine (DA) analysis,in vitro and in vivo,is primarily done through electrolytic oxidation,especially at carbon fiber microelectrodes.The diffusional properties of such electrodes suppress the current enhancement from biologically ubiquitous ascorbic acid (AA) through regeneration of DA by homogeneous reduction of dopamine quinone(DOQ).
