Electron-induced rapid crosslinking in supramolecular metal-peptide assembly and chemically responsive disaggregation for catalytic application

The applications of supramolecular metal-peptide assemblies as catalyst or precursor have recent attracted increasing attentions. In this work, a fragment the amyloid β-peptide, NH2-KLVFF-COOH, was assembled into nanofilms with encapsulated Pd, Pt and Au nanoparticles (NPs) via one-step room temperature electron induction method. effects building block, intermolecular interaction, driving force side-chain on assembly were investigated. mechanism thereby proposed. crosslinking peptide monomers results in mainly random unordered structures. obtained are extremely stable water at neutral pH for long term. However, metal NPs able to be responsively released under basic reductive conditions. show high activity catalyze reduction 4-nitrophenol. present studies responsive release will helpful design organic skeletons also future development stabilized metallic beyond catalysts.
