제목 Tyrosine mediated 2D peptide assembly and its role as a bio-inspired catalytic scaffold
초록 In two-dimensional interfacial assembly, interplay between molecular ordering and interface geometry determines the final morphology and local geometry. We present the spontaneous assembly of a designed peptide displaying facet formation of a water droplet. The identified peptides had a strong driving force to flatten the rounded top of hemispherical water droplet into a plane with a macroscopic 2D crystal structure. The facet formation phenomena is driven by interactions of tyrosine and cross-linked stabilization by cysteine. In this study, we revealed the crucial sequence motifs for facet formation and folding structures. The well-ordered redox active tyrosine in the 2D peptide film can enhance chemical/electrochemical reaction, and the assembled peptide film can potentially provide a platform to construct a molecularly tunable, self-repairable peptide or hybrid film.
