Microperoxidase 11(MP 11) was immobilized on the surface of a silanized glass carbon electrode by means of the covalent bond with glutaraldehyde. The measurements of cyclic voltammetry demonstrated that the formal redox potential of immobilized MP 11 was -170 mV, which is significantly more positive than that of MP 11 in a solution or immobilized on the surface of electrodes prepared with other methods. This MP 11 modified electrode showed a good electrocatalytic activity and stability for the reduction of oxygen and hydrogen peroxide.
