pubmed:abstractText |
Direct electrochemistry of hemoglobin was observed in stable thin film composed of a natural lipid (egg-phosphatidylcholine) and hemoglobin on pyrolytic graphite (PG) electrode. Hemoglobin in lipid films shows thin layer electrochemistry behavior. The formal potential E degrees ' of hemoglobin in the lipid film was linearly varied with pH in the range from 3.5 to 7.0 with a slope of -46.4 mV pH(-1). Hemoglobin in the lipid film exhibited elegant catalytic activity for electrochemical reduction of H(2)O(2), based which a unmediated biosensor for H(2)O(2) was developed.
