【摘要】 短肽分子的组装与组装体的表/界面性质是胶体与界面化学领域的重要研究内容。我们以阳离子短肽及无机多金属氧簇阴离子为构筑基元,通过分子间多重相互作用构筑了系列超分子组装体。我们发现富集在组装体表面的功能性氨基酸残基所形成的局部微环境能导致协同放大的表/界面效应。利用这一多价效应,我们成功实现了具有高效抗菌性的短肽纳米材料及水下仿生粘合材料[1-3]。更多还原

【Abstract】 Peptide assembly and the resultant interfacial property represent a significant theme in the field of colloid and interfacial chemistry.We have fabricated a series of supramolecular assemblies via the co-assembly of cationic peptides and inorganic polyoxomatelates based on multiple non-covalent interaction.We found that the highly concentrated amino acid residues located on the local surface of the assemblies promoted the binding capacity,which leading to the enhanced antimicrobial efficacy and underwater adhesion behavior.更多还原
