“…Photoelectrochemical (PEC) detection is a rapidly developing technique, due to its characteristics of high sensitivity, fast response speed, and simple instrumentation [1][2][3][4][5][6], and attracts a lot of research attention for detection of biomolecules, such as NADH, glucose, and glutathione, which are closely related to many serious diseases [7]. In PEC biosensors, photocurrent is produced by the physical and chemical interactions between biomolecules; photoactive species are identified as detection signal.…”

Oriented TiO2 nanotubes, which are fabricated by anodic oxidation method, are prospective in photoelectrochemical analysis and sensors. In this work, Pt and IrO2 co-modified TiO2 nanotubes array was prepared via a two-step deposition process involving the photoreductive deposition of Pt and chemical deposition of IrO2 on the oriented TiO2 nanotubes. Due to the improved separation of photo-generated electrons and holes, Pt-IrO2 co-modified TiO2 nanotubes presented significantly higher PEC activity than pure TiO2 nanotubes or mono-modified TiO2 nanotubes. The PEC sensitivity of Pt-IrO2 co-modified TiO2 nanotubes for glutathione was also monitored and good sensitivity was observed.
