Biocatalytic growth of Au nanoparticles immobilized on glucose oxidase enhances the ferrocene-mediated bioelectrocatalytic oxidation of glucose

Glucose oxidase, GOx, functionalized with Au nanoparticles is linked to a Au electrode. The biocatalytic enlargement of the Au nanoparticles yields a matrix for the immobilization of electroactive ferrocene units and the improved charge transport through the assembly enhances the ferrocene-mediated bioelectrocatalytic activation of the enzyme.
