摘要：

Here, polydopamine derivative monolayer was generated by electro-polymerization of thiol dopamine derivatives modified on gold electrode, and the adhesion of polydopamine made it being a platform for secondary reaction. The influence of pH on formation of polydopamine derivative was investigated. Horseradish peroxidase (HRP) was adhered on the polydopamine derivative monolayer electrode catalyzing the oxidation of H2O2. Cyclic voltammetry (CV) was used to detect the polydopamine monolayer as well as electrochemical catalysis of H2O2. Besides, electrochemical impedance spectroscopy (EIS) and atomic force microscope (AFM) were also employed to characterize the polymeric monolayer. (C) 2015 Published by Elsevier B.V.
