Sol-gel derived nanostructured cerium oxide film deposited on gold (Au) electrode has been utilized for physisorption of glucose oxidase (GOx). X-ray diffraction, atomic force microscopy, UV-visible spectroscopy, and electrochemical techniques have been used to characterize sol-gel derived electrode and bioelectrode. The response characteristics of the glucose bioelectrode indicate linearity, detection limit and shelf-life as , , and , respectively. The value of apparent Michaelis–Menten constant of bioelectrode has been found to be .
