In this research. TiO2 nanorods was fabricated on FTO/glass as electrode for the immobilized of Alzheimer's disease antibody by using 3-mercaptopropionic acid (MPA). Then, cyclic voltammetry method was used to test the current response to Alzheimer's disease peptide. The result shows that biggest change of current could nearly 2 μA. The light on/off cycle of illumination by LED with different wavelength was performed in Faraday cage to evaluate the photo response. With illumination by
