バイオミメティック系ワンプッシュリンクル形成と機能化

抄録

Many geometric patterns are seen in the natural world, including patterns that take form spontaneously by self-assembly. Among these, the “wrinkle” structure is very commonly seen on the surface of a leaf, on skin and brain. Additional mechanical factors in the outer layer of our cells play a large role in the formation and the morphogenetic process of our bodies and tissues. The concave-convex surface structure of wrinkles in the brain and that of folds in the intestines are both determined by the mechanical balance between the surface and cytoskeleton. In our study, these morphogenetic processes will be mimicked and the surface buckling phenomenon will be used to create a variety of minute wrinkle structures on the surface of silicon rubber. Moreover, we adopted wrinkle to prepare various application fields, such as SERS sensing film and superhydrophobic surface.
