Typically, the morphologies of the self-assembled nanostructures from block copolymers are limited to spherical micelles, wormlike micelles and vesicles. Now, a new generation of materials with unique shape and structures, cylindrical soft matter particles (tubisomes), are obtained from the hierarchical self-assembly of cyclic peptide-bridged amphiphilic diblock copolymers. The capacity of obtained photo-responsive tubisomes as potential drug carriers is evaluated. The supramolecular tubisomes pave an alternative way for fabricating polymeric tubular structures, and will expand the toolbox for the rational design of functional hierarchical nanostructures.
通常情况下,嵌段共聚物自组装纳米结构的形态仅限于球形胶束、蠕虫状胶束和囊泡。现在,通过环状肽桥联两亲性嵌段共聚物的分级自组装,得到了具有独特形状和结构的新一代材料——圆柱形软物质颗粒(tubisomes)。评估了所得光响应 tubisomes 作为潜在药物载体的能力。超分子 tubisomes 为制备聚合物管状结构开辟了另一种途径,并将扩展用于合理设计功能分级纳米结构的工具包。
