Fig. 7. DPV of glucose oxidation of GCE/TiO2 NW/PAPBA–Au TNC (a and a′), GCE/PAPBA–Au NC (b and b′), GCE/TiO2 NW/PAPBA NC (c and c′), GCE/pristine PAPBA (d and d') and bare GCE (e) in 1 mM glucose + 0.1 M PBS solution (solid lines; a′–d′) and absence of glucose (dashed lines; a–e). Scan rate: 0.05 V s−1, pulse amplitude: 0.05 V, pulse width: 50 ms.
