| Popis: | Due to the separation of the excitation source and detection signal, the use of photoelectrochemical (PEC) glucose sensors is regarded as a promising electrochemical approach offering high sensitivity for glucose analysis by photoelectrocatalytic oxidation of glucose. In this study, we present a PEC glucose sensor based on TiO2 nanorod array (TiO2NRA) electrode, exhibiting high sensitivity of around 200 μA cm−2 mM−1 in glucose detection for the concentrations in the range of 0.01–0.20 mM. Moreover, the TiO2NRA can be fabricated and used in a photo fuel cell (PFC) to generate electricity. This investigation expands the applications of TiO2 and provides a high sensitive way for glucose sensing.
