This seminar presents examples of bioadhesions inspired by mussels and geckos. First, the speaker will present a simple one-step aqueous surface modification method called poly(dopamine) coating. This surface chemistry is inspired by mussel adhesive proteins found in marine environment. The adhesive protein shows a repeated di-peptidyl sequence of DOPA (3,4 dihydroxylphenylalanine) and lysine that are exhaustively repeated throughout the protein. We found that dopamine, a bi-functional small molecule that has amine and catechol, which are the side chains of lysine and DOPA showed a versatile surface coating capability1. We found that under oxidative conditions (pH ＞ 7.5), dopamine surprisingly forms adherent nanofilms on virtually all natural and synthetic surfaces: metals, oxides, semiconductors, polymers, and ceramics. |
