(A) Recorded CVs under N2-saturated (dash line) and O2-saturated attributed to BOx immobilized on bare Au electrode (a) AuNSs modified Au electrode (b) PTCA-Au electrode prepared by conventional three-electrode system (c) and bipolar electrochemistry method (d) along with schematic of their specific orientations. (B) Recorded CVs under N2-saturated (dash line) and O2-saturated for BOx immobilized onto PTCA/Au electrode prepared by BPE in ACN solution with different percent of water 0% (a) 5% (b) 15% (c). (C) CVs attributed to BOx immobilized on PTCA-modified Au electrode under O2-saturated after 1 cycle (solid line) and after passing some days (dash lines). Experimental condition: 0.1 M PBS, pH = 6, scan rate = 20 mV s−1.
