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 wavelength of 470 nm could have an acceptable photocurrent, which could have less damage to biorelated spices comparing to UV illumination. 15% increases of current could be achieved by this illumination on TiO2 nanorod. , which is proven for larger signal for Alzheimer’s disease detection.
