dc.description.abstractIn this study, we report the simple and sensitive electrochemical detection of dopamine in the presence of excess ascorbic acid. The detection is based on the spontaneous formation of electrocatalytic poly(dopamine) films on bare indium?tin oxide (ITO) electrodes. The poly(dopamine) films are formed by immersing ITO electrodes in a solution of dopamine and ascorbic acid for 10 min. Afterwards, the electrocatalytic oxidation of hydrazine is measured using modified electrodes. The electrooxidation current of hydrazine increases with increasing dopamine concentration. This method allows a detection limit of 1 nM for dopamine in the presence of 100 mu M of ascorbic acid.-
