Photoelectrochemical sensors have been studied for glucose detection because of their ability to minimize background noise and unwanted reactions. Titanium dioxide (TiO2), a highly efficient material in converting light into electricity, cannot utilize visible light. In this regard, we developed nonenzymatic sensor by using simple one-step electrospinning technique combine cupric oxide with TiO2 create heterojunction. The prepared nanofibers exhibit an extremely high aspect ratio dense structure. These characteristics enhance the quantity electron-hole pairs generated speed at which electrons are transferred. They also reduce distance that charges need travel offer reactive sites catalytic oxidation glucose. has direct proportional reaction within concentration ranging from 30 μM 2 mM under sunlight conditions. It achieves limit 9.9 signal-to-noise 3. excellent stability, reproducibility, selectivity. This study provides insights development photoelectrochemical detect
