| 研究実績の概要 |
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.

理由
For the nanotransistor sensor device, we achieved the results as planned. This includes new devices of ideal dimensions to be operated in a ball under pressure. We also proceeded with the design and construction of a liquid pumping system for sensor operation at underwater environment and were able to demonstrate a new liquid pumping principle. On the other hand, we had planned to proceed to the implementation of the test of the sensor device under high-pressure environment in this fiscal year, but it took time for the evaluation of the sensor device, etc., so we only made preparations for the test.

| 今後の研究の推進方策 |
Since the next fiscal year will be the final year of this research, a proof of principle under atmospheric pressure and high pressure conditions will be conducted with the integration of a nanotransistor sensor and a compact pumping system. For this purpose, we will establish interface technology for the integration of the sensor device and the pumping system that we have fabricated so far. In addition, we will publish the results of our research through and participate in academic conferences and other events.
