Electrochemical redox of hemoglobin at poly(o-phenylenediamine) film modified electrodes or promoted byo-phenylenediamine

Electrochemical redox of hemoglobin at poly(o-phenylenediamine) coated glass carbon electrodes or at bare glass carbon electrodes promoted byo-phenylenediamine have been investigated. The electrochemical characters of poly(o-phenylenediamine) films have also been studied by using cyclic voltammetry and potential-step chronoamperometry as well as current-step chronocoulometry techniques. A possible catalyzing mechanism for hemoglobin is proposed. Supported by the National Natural Science Foundation of China Ye Baoxian Born in July 1958. Ph.
