▎ 摘　　要

NOVELTY - Complex formed from a cofactor tethered to a graphene-like material, where the cofactor is attached, via a covalent bond, to a tethering molecule which is attached to the graphene-like material via pi - pi stacking, is new. USE - The complex formed from a cofactor is useful as biosensors for clinical diagnostic, food industry, medical drug development and environmental and military applications, and in reagentless biofuel cells for power generation. ADVANTAGE - The complex enables suitable immobilization of the cofactors without unduly inhibiting their ability to perform their desired biological function and minimizes the cost of production and/or synthesis of pharmacological compounds. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for attaching a cofactor to a graphene-like material comprising covalently attaching the cofactor to a tethering enzyme and attaching the tethering enzyme to the graphene-like material via pi - pi stacking.
