Cyclic voltammogram of cellulose/polypyrrole (CPPy)/INV/MUT/FDH/GDH but without AuNP-NQ on the electrode in the presence of 100 mM fructose (red solid line) and 100 mM glucose (black dashed line); all measurements were performed at a scan rate of 5 mV s⁻¹. McIlvaine buffer pH 6 was purged with argon. Thinner lines denote background currents in the absence of sugar.
