Outline of Final Research Achievements |
In this project, a novel membranous devise (material) was developed. Membrane-on-Membrane (MoM) was hierarchically composed by self-assembled membranes. Liposome was selected as core unit of MoM, because it showed unique functions such as recognition of L-amino acid, promoting organic reaction in water, and molecular orientation of chlorophyll. In addition, the methodologies, multiple-fluorescent probe analyses, membrane surface-enhanced Raman spectroscopy, dielectric dispersion (relaxation) spectroscopy, were developed to characterize the physicochemical properties of membranes (in micro- and mesoscale). As an example of our achievements, the “ordered” membrane property plays a crucial role to improve selectivity in chiral recognition of amino acid. When the liposome possessing ordered membrane property was applied to MoM device (for example, liposome-immobilized polyacrylamide hydrogel system), the chiral recognition ability could be maintained.

Academic Significance and Societal Importance of the Research Achievements |
Liposome膜は,酵素に類似した分子認識・変換機能(LIPOzyme機能)を誘導する事が示されている.一連の成果は世界的に見て類のない研究であり,当研究Gr.が発信した独創的な機能性材料である.近年では生体模倣(Biomimetic)材料が多数報告されているが,結局のところ,生体系由来の機能を付与した材料に留まっている.本研究で得た一連の知見では,自己組織化膜のしなやかな構造を最大限に活用し,酵素と同様に構造ゆらぎにより認識/変換を制御しているため(Bio-Inspired),従来にはない独創的研究といえる.さらにMoMは状態に応じて進化しうる材料であり,極めて進歩的な技術開発といえる.
