摘要：By one-step co-electrodeposition Hemoglobin (Hb) and Au nanoparticles-chitosan (Au NPS-Chi) nanocomposite film on carbon ionic liquid electrode(CILE), the Hb immobilized with Au NPS-Chi nanocomposite film was stable and retained its functional activity. The results of cyclic voltammetrys showed a pair of well-defined and quasireversible redox peak of Hb with the formal potentials of -0.545V (vs.SCE) in 0.1 mol/L pH 7.0 PBS; a linearity range for determination of H2O2 is from 0.4 to 208.4 mu mol/L with a detection limit of 0.12 mu mol/L (S/N=3). As a results, the one-step co-electrodeposition and the promising feature of nanocomposite could serve as a versatile platform for the fabrication of electrochemical biosensors.
