Recent Developments of Nanostructured Electrodes for Bioelectrocatalysis of Dioxygen Reduction

Figure 9

Cyclic voltammograms (second scan) obtained with ITO electrode coated by (i) one, (ii) six, (iii) twelve, and (iv) twenty-four immersion and withdrawal steps followed by laccase adsorption. Experiments were performed in dioxygen-saturated 0.1 mol dm⁻³ phosphate buffer (pH 4.8). Scan rate 0.001 V s⁻¹ (from [12]).
