In silico による高感度・高選択的な機能性試薬の設計開発
Design and development of high sensitive and selective functional reagent in silico

研究の背景 Background

生体もしくは環境中の極微量成分を検出において反応もしくは試薬に強く依存するため,より一層の高感度・高選択的な反応もしくは機能性試薬が強く求められています.極微量成分の検出では,用いる反応の詳細な理解と反応環境の再構築が重要となっています.

More high sensitive and selective reactions and/or functional reagents are required strongly because detection of infinitesimal elements in biological objects or environment depends on reactions and/or reagents themselves. Realizing the used reactions in detail and restructuring the reactive environment has the key to detect infinitesimal element.

研究の目標 Outcome

様々なシミュレーションとinsilicoスクリーニングを用いて多面的に解析評価を行うことにより,高感度・高選択的な機能性試薬や反応環境の再構築の設計を目指しています.得られた知見に基づき,新たな反応又は試薬の実用化に向けてを行っています.

The main objective of the research is to design the high sensitive and selective functional reagents and to reconstruct the reactive environment from analytical evaluation using various simulations and/or in silico screening. The obtained new knowledge is applied to put into practical use of new reactions and/or functional reagents.
