A non-enzymatic glucose sensor and method for fabricating the sensor are disclosed. The glucose sensor contains at least one non-enzymatic electrode configured to catalyze the electro-oxidation of glucose in preference to other bio-molecules. The surface of the electrode comprises CuO nanoparticles. The sensor shows sensitivity and selectivity exceeding enzyme based devices presently in use.
