Sol-gel derived nanostructured cerium oxide (CeO2) 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 CeO2Au electrode and GOxCeO2Au bioelectrode. The response characteristics of the glucose bioelectrode (GOxCeO2Au) indicate linearity, detection limit and shelf-life as 50400mgdL, 12.0μM, and 12weeks, respectively. The value of apparent Michaelis–Menten constant (Km) of GOxCeO2Au bioelectrode has been found to be 13.55μM.
