抄録

A facile strategy of an amperometric biosensor for hydrogen peroxide based on the direct electrocatalysis of hemoglobin (Hb) immobilized on gold nanoparticles (GNPs)/1,6-diaminohexane (DAH) modified glassy carbon electrode (GCE) has been described. A uniform monolayer film of DAH was initially covalently bound on a GCE surface by virtue of the electrooxidation of one amino group of DAH, and another amino group was modified with GNPs and Hb, successively. The fabrication process was characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM). The proposed biosensor exhibited an effective and fast catalytic response to the reduction of H<sub>2</sub>O<sub>2</sub> with good reproducibility and stability. A linear relationship existed between the catalytic current and the H<sub>2</sub>O<sub>2</sub> concentration in the range of 1.5 × 10<sup>-6</sup> to 2.1 × 10<sup>-3</sup> M with a correlation coefficient of 0.998 (<i>n</i> = 24). The detection limit (<i>S/N</i> = 3) was 8.8 × 10<sup>-7</sup> M.
