A novel electrochemical biosensor based on the hemin-graphene nano-sheets and gold nano-particles hybrid film for the analysis of hydrogen peroxide

A novel hemin-graphene nano-sheets (H-GNs)/gold nano-particles (AuNPs) electrochemical biosensor was constructed for analysis of hydrogen peroxide. Due to the synergy effect of H-GNs and AuNPs, the biosensor showed a satisfactory electrocatalytic activity for the reduction of hydrogen peroxide.
