A heme-histidine-sodium decyl sulfate nano micelles complex with peroxidase activity (MAP) was constructed self-assembly and immobilized on a hydroxy fullerene modified glassy carbon electrode. The cyclic voltammograms of the modified electrode with a pair of redox peaks were investigated. The formal potential of the MAP modified electrode was determined to be -0.312V, at a scan rate of 0.05V/s in 50 mmol/L sodium phosphate buffer solution (pH 8.0). The electron transfer rate constant (ks) and cathodic transfer coefficient (α) were 1.96s-1 and 0.4, respectively. The cathodic peak current of the MAP modified electrode responses linearly to hydrogen peroxide ranging from 300 µmol/L to 1700 µmol/L. The detection limit was concluded to be 32 µmol/L. The apparent Michaelis-Menten constant (Kmapp) could be determined to be 1.08 mmol/L.
