Effect of applied potential on the adsorption kinetic of 0.50 mg·mL−1 GOx after adsorption of a GOx layer (4.1 ± 0.3 nm) onto OTCE at OCP. Adsorption experiments were performed in 10 mmol·L−1 citrate buffer at pH = 4.2 and a flow rate of 1 mL·min−1 at: A) OCP; B) +500 mV; C) +650 mV; D) +750 mV; E) +800 mV; and E) +950 mV. The arrow shows the time which the external potential was applied.
