Glucose monitoring devices for disposable, inexpensive, reliable biosensors are particularly required for diagnosis and medical treatment of diabetic patients. The majorities of sensors are based on electrochemical principles and employ enzymes as biological components for molecular recognition. The objectives of this research are to design and fabricate glucose sensor using enzyme based amperometric sensor on glass substrate. Microfabrication technology was used to fabricate the electrode. The biosensor developed initially to determine glucose in aqueous solutions, with later application to others analytes. The glucose electrode itself consists of a silver silver chloride reference electrode, a working electrode and a counter electrode. Characterization of the reference electrode has been evaluated. The output potential and noises are observed at random times and the potential variation of the two reference electrodes is less then 1 mV. It is due to copper wire silver paste coated was used but with unknown purity.
