Outline of Final Research Achievements

Fragrance products have been paid much attention to improvement of quality of life. However, their effect is often insufficient due to flowing by sweats and short-term evaporation of odor molecules. On the other hands, adhesive nanomaterials such as nanosheets has shown an excellent adhesiveness on various interfaces via a physical adsorption. In fact, we demonstrated fabrication procedure of polysaccharide nanosheets and nanofibers carrying cyclodextrin, which can be incorporated various hydrophobic molecules including odor molecules for adhesive fragrance materials.

Academic Significance and Societal Importance of the Research Achievements

本研究によって、におい分子の吸着・徐放を自在に操る“貼るナノ透明体”の創製法を確立した。これにより、従来の脱臭・芳香剤の課題（持続性）を解決するための方策を提唱することができ、学術的意義や社会的意義は大きい。また、におい分子に限らず薬剤等も包接可能であることから、新しい薬剤徐放性ナノ材料としてバイオマテリアル研究領域にも貢献できる技術になると考えられる。
