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.

由于激发源和检测信号的分离，使用光电化学（PEC）葡萄糖传感器被认为是一种有前途的电化学方法，可通过葡萄糖的光电催化氧化为葡萄糖分析提供高灵敏度。在这项研究中，我们提出了一种基于TiO ₂纳米棒阵列（TiO ₂ NRA）电极的PEC葡萄糖传感器，在浓度范围为0.01–0.20 mM的葡萄糖检测中，显示出约200μAcm ^-2  mM ^-1的高灵敏度。。此外，可以制造TiO ₂ NRA并将其用于光燃料电池（PFC）中以发电。这项研究扩展了TiO ₂的应用 并为葡萄糖感测提供了一种高灵敏度的方法。
