Abstract:A novel graphene-polydopamine nanomaterial with biomimetic functions was synthesized.The graphene-polydopamine nanomaterial was applied in the fabrication of H2O2 biosensors by using hydroquinone as electron mediator.The modified electrode exhibited good electrocatalytical activity to H2O2.The linear range was from 5.0×10-7 to 3.3×10-4 mol/L with a detection limit of 3.7×10-7 mol/L(S/N=3) and the linear correlation coefficient was 0.9995.
Keywords:Polydopamine  Graphene  Hydroquinone  Horseradish peroxidase  Hydrogen peroxide
