This year's objective was to evaluate the nanosensors that had been fabricated in the previous fiscal year, and to evaluate sensors with integrated rare-earth element-selective layer under atmospheric pressure conditions and under high pressure conditions. For the sensor devices, performance was evaluated on a tabletop under atmospheric pressure conditions, such as Lanthanum and Yttrium. For the high-pressure test, we have demonstrated the possibility to operate a silicon-based liquid pumping device utilizing high pressure at deep-sea to demonstrate the principle of energy-free liquid pumping. We have understood its characteristics, and prepared for functional integration of the sensor device and microfluidic system. Density functional theory (DFT) calculation was carried out to optimize the complex of the designed receptor and the target metal ion. According to the optimized receptor design, synthesis of the artificial receptor was performed.
