Abstract :
The development of high sensitive miniaturized sensors is of special importance for "Lab on a Chip" and biosensors development. In this context and due to its n-type semiconductor character and its high chemical stability, TiO2 thin films have been proposed for application as pH and H sensors. Even more, taking advantage of their high specific surface, TiO2 nanotubes have been also considered as a natural candidate for application in pH detection.
