We have studied the Light Addressable Amperometric Sensor (LAAS) which is a two dimensional electrochemical sensor. In this study we report the LAAS that enables multiples samples measurement based on planer structure made by photolithography. We deposited SU-8 and platinum films on the LAAS device to form well array in order to keep individual sample solutions. The LAAS performs individual measurements by selecting each well using addressing light beam. The results showed that the observed current value depends on concentration of redox species from 10pM to 1 mM in 1 well. Therefore, we found that the proposed structure functions correctly, and expect efficiency improvement of processes such as drug discovery screening
