Laccase immobilization onto electrode surface using graphene and gold nanoparticles for phenols determination

A method is described for fabrication of an electrochemical biosensor to detect catechol based on adsorption immobilization of Lac onto gold- cetyltrimethylammonium bromide electrodeposited onto a glassy carbon electrode that is modified with graphene oxide physically. The modified electrode was characterized by voltammetry, and Scanning Electron Microscopy (SEM) techniques.
