Recent Developments of Nanostructured Electrodes for Bioelectrocatalysis of Dioxygen Reduction

Figure 11

Cyclic voltammograms (second scan) obtained with ITO electrode coated by (i) one, (ii) three, (iii) six, and (iv) nine immersion and withdrawal steps alternatively into suspension of negatively and positively charged carbon nanoparticles, followed by bilirubin oxidase 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 [13]).
