Outline of Research at the Start

本研究では、無機材料合成アプローチにより、小型基板上に分子フィルター機能・分子濃縮機能・センサ機能を併せ持つ集積化化学センサシステムを創成する。空間選択的な無機ナノ材料合成技術とこれを応用したナノ固体表面機能の設計により、従来化学センサでは原理的に実現困難であった、多成分夾雑分子群存在下における微量標的分子の検出をその長期動作安定性・耐熱堅牢性と共に実証する。提案するセンサシステムでは、固体表面-分子間の相互作用に基づく時空間分子輸送制御が可能であり、異なる時間軸で多成分分子群のセンシングを行うことで分子識別機能の劇的な改善が期待できる.

Outline of Annual Research Achievements

We have donate the research to manipulate the area of nanowire concentrator with the sensor during the last year. As the problem which mentioned before, tiny concentrator hardly the molecule/water adsorption amount, and huge concentrator will sacrifice the design of portable sensor. Therefore, we design a flexible concentrator for intergrating with a sensingtive gas sensor. Flexibel PI substrate is choosen and nanostructored ZnO materal could be area selectively synthesised on this substrate as molecule concentrator. Such design successfully solve the problem, and we can conduct the gas molecule capter-desorption-transfer expermental which proposed in the topic.
