Hierarchical Self-assembled Photo-Responsive Tubisomes from Cyclic Peptide-Bridged Amphiphilic Block Copolymer.

Typically, the morphologies of the self-assembled nanostructures from block copolymers are limited to spherical micelles, wormlike micelles and vesicles. Herein, we report a new generation of materials with unique shape and structures, cylindrical soft matter particles (tubisomes), obtained from the hierarchical self- assembly of cyclic peptide-bridged amphiphilic diblock copolymers. Additionally, the capacity of obtained photo-responsive tubisomes as potential drug carriers is evaluated. The supramolecular tubisomes described here paves an alternative way for fabricating polymeric tubular structures, and will expand the toolbox for the rational design of functional hierarchical nanostructures.
