Topic title: Bioinspired Functional Surface for Biointerface and Bioelectronics
Abstract: Prevention of soft tissue injury is very necessary for surgery, especially minimally invasive surgery. Clipper or scalpel, in general, is hold tightly to prevent slipping of soft tissue, which usually leads to tissue injury. Several researches have demonstrated that surface micro-pattern have great impact on their functions such as anti-slipping and anti-adhesion. How to design and fabricate upon surgical instrument is gradually becoming an important research topics. Nature surface has been evolved to hierarchical structures with superior function, which is regarded as treasure vault for inspiration of biomimetic surface. In this paper, we investigated the anti-adhesion and anti-slipping of Nepenthes mirabilis and pad of tree frog on basis of SEM images, and unveiled the structural effect on their surface function. Especially, the unique microscale fluid behaviour was discovered by investigation on the bio-inspired surface structure. Apart from the design of biomimetic surface, their fabrication of complicated surface structure of surgical instrument was exploited and their efficiency was validated by performing experiments of soft tissue.
