Direct electrochemical reduction of single-layer graphene oxide and subsequent functionalization with glucose oxidase

Direct electrochemical reduction of single-layer graphene oxide and subsequent functionalization with glucose oxidase

A direct electrochemical method to reduce single-layer graphene oxide (GO) adsorbed on the 3-aminopropyltriethoxysilane (APTES)-modified conductive electrodes is proposed. The reduced GO adsorbed on glassy carbon electrode was modified with glucose oxidase (GOx) by covalent bonding via a polymer gen...
