AuNPs supported on appropriate scaffolds are highly active and can catalyse many reactions,for example,the oxidation of glucose.In this view,AuNPs can be used as a glucose oxidase mimic.H2O2 is produced along with the oxidation of glucose,which is poisonous to human body.Heme is the active center of peroxidases,which can assemble with peptides and catalyse a serious of H2O2 related reactions.
