| Outline of Final Research Achievements |
In this study, we aimed to realize ultra-compact in-situ measurement devices that can be used in the marine environment. In particular, we conducted research and development to realize flow-analyzers with state-of-the-art optical measurement technology. We adopted a micro PMT (photo multiplier tube) as a photodetector and the microfluidic device for ATP (adenosine triphosphate, proxy of microbial biomass) determination was miniaturized utilizing a 3D printer technology. Furthermore, we demonstrated that the micro PMT can be used underwater condition by applying oil-immersed configuration without a pressure-resistant housing. As a result of the above research and development, we achieved the ultra-miniaturization of the entire in situ ATP analyzer, and were able to demonstrate the possibility of simultaneous measurement of multiple environmental parameters by mounting it on a small desktop-size underwater robot together with various underwater sensors through the sea trial.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の成果を応用することで、海中で使用される分析装置の中でも、高感度な光計測を必要とする微量金属や生体関連成分の分析を目的とした装置の超小型化が可能になる。これにより、小型の海中プラットフォームへの分析装置の搭載が可能になるため、広大な海洋環境の網羅的な計測を目指す分散センシングなどに応用可能である。小型化された分析装置は、地球環境変動のより詳細な把握や新たな資源の探査および環境影響評価など、多様なミッションに適用可能であり、新たな海洋科学・海洋利用に資すると共に、人類社会の持続的な発展に貢献できる。
