our great attention. TEM studies demonstrated that it is formed via a hierarchical self-assembly, i.e., a series of successive processes, including micellization, micelles alignment forming nanofilament, branching of the nanofilaments by micelles, and finally nanowire formation. As far as we know, such hierarchical self-assembly process with high complexity has not been observed in literature for glycopolypeptides
模仿自然界中多样的糖缀合物结构一直是科学家的梦想。目前,肽和糖的天然缀合物的分层自组装结构无法通过线性糖多肽与单糖作为附件轻松实现。在这项工作中,通过使用一系列精心设计的交替两亲性糖多肽刷(AAGBs)与糖树突和短肽的悬垂物,实现了各种自组装形态,包括纳米线、纳米带和复合胶束,主要取决于数量比。氨基酸种类 (S/F) 的糖单位。在这些形态中,纳米线引起了我们的极大关注。TEM 研究表明,它是通过分层自组装形成的,即一系列连续过程,包括胶束化、胶束排列形成纳米丝,纳米丝通过胶束分支,最后形成纳米线。据我们所知,这种高度复杂的分层自组装过程在糖多肽甚至多肽的文献中都没有观察到,这将加深我们对天然糖缀合物自组装机制的理解,扩展仿生材料库。
