A novel sensor for the determination of glucose was prepared by immobilizing Chitsosan and Au-Ni composite matrix on the surface of glassy carbon electrode. The preparation of Au-Ni was characterized by XRD, and the electrochemical characteristics of the sensor was investigated by cyclic vohammetry, ae impedance method and amperometric i-t curve. The method showed good linearly for 2.5 x 10-5- 9.5 x 10-4 mol/L glucose with a detection limit of 1 x 10-5 mol/L The correlation coefficient was 0.995 O. Some common orgaNic acids such as uric acid and aseorbic acid did not interfere with the detection of glucose.
