ソフトマテリアル表面を探査する自律走査型マルチアクティブプローブ法の開発（国際共同研究強化）

Outline of Final Research Achievements

Studying mechanical deformation at the surface of soft materials has been challenging due to the difficulty in separating surface deformation from the bulk elasticity of the materials. To overcome this issue, we introduced a new approach for studying the surface mechanical deformation of a soft material by utilizing a large number of self-propelled microprobes driven by motor proteins on the surface of the material. Information about the surface mechanical deformation of the soft material is obtained through changes in mobility of the microprobes wandering across the surface of the soft material. The active microprobes respond to mechanical deformation of the surface and readily change their velocity and direction depending on the extent and mode of surface deformation. In this project we explored possible applications that could benefit not only the surface science but also the life science.
