Electroreduction of dioxygen on Aunano-DNA film electrode in acidic electrolyte.


The colloidal Au nanoparticles-deoxyribonucleic acid (Au(nano)-DNA) film modified glassy carbon electrode (GCE) has been fabricated and the electrochemical reduction of dioxygen (O(2)) at this modified GCE has been studied in 0.2 mol/L air-saturated acetate buffer (pH=5.2) using cyclic voltammetry (CV), chronocoulometry (CC), linear scan voltammetry (LSV… (More)
