Outline of Final Research Achievements

In our recent study, we have realized the world's first high-quality nanoporous metal (metal nanoporous material) using amphipathic molecules such as surfactants and block copolymers. This material possesses a porous body with high electrical conductivity whose skeleton is formed only from metal and is expected to be applied to an electrochemical system different from the conventional nanoporous inorganic oxide system. In this research, we further expanded these concepts and promoted their development in glucose sensors. In addition to aiming to develop a glucose sensor, we also aimed to construct a new theory by making the best use of the characteristics of metal nanoporous materials and understanding the correlation between physical properties and nanostructures. Finally, we developed a flexible device.

Academic Significance and Societal Importance of the Research Achievements

近年，分子同士の相互作用による「自己組織化」現象は，高次構造制御されたナノ材料をボトムアップ的に合成する方法として注目されている．その中でも両親媒性分子などを利用し，ナノレベルで細孔構造制御された多孔性物質の合成が可能である．米国Mobil社が提案した鋳型法による酸化物等のメソ領域における空間形成は，世界的に1990年代から活発に研究がなされ，合成条件を変えることで，様々な形態（ナノ粒子，薄膜など），組成（遷移金属酸化物，炭素，高分子など）のメソ多孔体が報告されてきた．本研究で扱う金属系ナノ空間材料は，その中でも特にユニークな材料であり，学術的なインパクトが高いと思われる．
