The modified electrode exhibits strong promoting effect and high stability toward the electrochemical oxidation of dopamine(DA), which gives reversible redox peaks at a formal potential of 0.192 V(vs.Ag/AgCl) in a pH=7.0 phosphate buffer (solution).

• 研究了多巴胺(DA)在该修饰电极上的电化学行为；结果发现；这种纳米粒子对DA的氧化具有良好的催化作用。 在pH=6.；0的磷酸缓冲溶液中；DA在该修饰电极上的氧化还原式电位为0
