The electron transfer process of hemeproteins on the electrode surface is considered a promising subject in the area of bioelectrochemistry. Electrochemists believe that electron transfer between electroactive proteins and electrode surface might be expected to simulate the electron transfer between proteins. This research provides information about the electron transfer mechanism in biological system. Cytochrome c is a typical electron transferring protein,

The electrochemical behavior of Alizarin Red S(ARS) on GC electrode has been studied in acidic condition by spectroelectrochemistry with LOPTLC. It was found that there are three electrochemical reactions and followed by a chemical reaction of ARS in the potential range of 1.00——0.60V. The mechanism of electrode reactions has been studied and suggested based on the informations obtained from electrochemical and insitu spectroelectrochemical experiments.

The electrochemical behavior of myoglobin at a Brilliant Cresyl Blue (BCB) modified platinum gauze electrode and spiral pt wire in the BCB solution in optically transparent thin layer cell base been investigated by using cyclic potential-absorbance method and double potential step chronoabsorptometry. The results reveal a reversible electron transfer resection of myoglobin. Exhaustive reductive and oxidative electrolyses are achieved at the modified platinum surface in 20 and 100s respectively. The formal h...
