NADH Oxidation onto Different Carbon-Based Sensors: Effect of Structure and Surface-Oxygenated Groups

Figure 6

Cyclic voltammetries obtained for NADH over (a) GCE/MWCNT and (b) GCE/O-MWCNT at an initial potential before to the reduction potential peak. Scan rate: 100 mV·s⁻¹, NADH concentration: 1 mmol·L⁻¹.
