Effect of GOx concentration on adsorption at +800 mV of: A) 0.01, B) 0.05, C) 0.10, and D) 0.50 mg·mL−1 after a GOx layer (4.1 ± 0.3 nm) was adsorbed onto OTCE at OCP. All experiments were performed in 10 mmol·L−1 citrate buffer at IEP and a flow rate of 1 mL·min−1. The arrow shows the time which the external potential was applied.
