Abstract

Regular polyvinyl alcohol arrays were prepared with porous polystyrene films by a self-assembly method. Cyt c immobilized on PVA microlens arrays modified glassy carbon electrodes gave a pair of stable,well-defined and quasi-reversible cyclic voltammetric peaks at about 0.072 V (vs. Ag/AgCl) in 0.1 mol/L PBS buffer (pH = 6.89) solution. The effects of scan rate,pH and concentration of buffers on the electrochemical behaviors of Cyt c were studied in detail. The apparent heterogeneous electron transfer rate constant (k0) was evaluated to be 2.98×10-6 cm·s-1.
