A "signal-on" photoelectrochemical (PEC) biosensor was developed for ultrasensitive detection of vascular endothelial growth factor 165 (VEGF165) based on a Ti3C2/BiVO4 Schottky junction, which was a novel sensitized structure with excellent photovoltaic performance, prominent film-forming ability and stability. The generation of a built-in electric field by the Ti3C2/BiVO4 Schottky junction efficiently suppressed the combination of photogenerated electron-hole pairs and enhanced the photocurrent, providing a high initial photocurrent signal for the construction of a photoelectrochemical (PEC) biosensor.
一种基于 Ti3C2/BiVO4 肖特基结的“信号开启”光电化学（PEC）生物传感器被开发出来，用于超灵敏检测血管内皮生长因子 165（VEGF165）。这是一种具有优异光伏性能、突出成膜能力和稳定性的新型敏化结构。Ti3C2/BiVO4 肖特基结产生的内置电场有效地抑制了光生电子-空穴对的复合，增强了光电流，为光电化学（PEC）生物传感器的构建提供了高初始光电流信号。
