Direct electron transfer of hemoglobin founded on electron tunneling of CTAB monolayer

Article Abstract:

Direct electron transfer and stable adsorption of hemoglobin (Hb) on a carbon paste (CP) electrode are obtained with the help of a single-chain cationic surfactant, such as cetyltrimethylammonium bromide (CTAB). The studies have indicated that CTAB can form a complete monolayer with a high density of positive charges on the surface of the CP electrode, which has adsorbed negatively charged protein molecules via electrostatic interactions.
