Abstract

According to self-polymerization property of dopamine and reductibility, polydopamine/silver composite/graphene was synthesized in one step. In addition, the graphene compound fixing on the surface of glassy carbon electron as a working electrode was used to construct a non-enzymatic glucose sensor. With a series of characterization methods such as X-ray power diffraction (XRD) and Raman spectrum, polydopamine/silver composite/graphene is synthesized successfully. Further, concentration of polydopamine/silver composite can be controlled by the reactive time. Electrochemical performance was tested with electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The biosensor has shown a good linear relationship under the condition that concentration of glucose is between 5 mmol/L and 9 mmol/L

Key words： graphene oxide; dopamine; Ag; glucose sensor
