A novel ordered macroporous polycysteine/Cu composite film (DOM PCE/Cu) was successfully prepared by electrochemical deposition method using polystyrene spheres as templates on a bare glassy carbon electrode (GCE). The structure and electrochemical properties of DOM PCE/Cu film were characterized. The DOM PCE/Cu composite film modified electrode exhibits good electrochemical catalytic activity toward the oxidation of glucose, which may be related to the structure of DOM PCE/Cu film. The non-enzymatic glucose sensor has a wide linear range from 2 mu M to 2.9 mM, with a low detection limit of 0.8 mu M. The modified electrode also has highly sensitive and fast amperometric (within 3 s) sensing of glucose, thus it can be used for the future development of non-enzymatic glucose sensor.
