摘要：
A novel approach for glucose biosensor fabrication was described. It based on immobilization of glucose oxidase on polyaniline/graphene composite membrane modified glassy carbon electrode. Cyclic voltammetry demonstrated that modified electrodes owned good electrochemical activity, superior sensitivity and high stability. The good electrocatalytical activity toward H2O2 and O-2 might be attributed to the synergistic effect of graphene and polyaniline. The results showed that the electrochemical biosensor had a wide linear response from 0.1 to 10 mM.
