要約(英語): Currently, research on olfactory and taste sensors is being actively conducted, and the demand for molecular recognition is increasing. We have successfully developed an electrochemical sensor called Light Addressable Amperometric Sensor (LAAS). In this study, we used our organic-inorganic hybrid type LAAS with CuPc/n-Si/Al structure to verify its behavior in molecular recognition. As a starting point, we investigated the simplest reaction, hydrophobic bonding, as part of molecular recognition. The gold working electrodes on LAAS were modified by Self-Assembled Monolayer. We evaluated the device in terms of concentration dependency and image measurement. The measurements were carried out using a solution with redox substances and quinine as a hydrophobic substance. As a result, we confirmed the concentration dependence that the LAAS current value increases as the concentration of quinine increases. We also confirmed the reproducibility of the sensor because a device with the same characteristics was successfully fabricated by the same process.
