    Cooperative Self-Assembly of Polypeptide Homopolymer/Block Copolymer into Helical Nanotoroids

    • Toroids have attracted widespread attention due to their unique structures and properties. Chiral structures are ubiquitous in nature and chiral materials display excellent performance in diverse fields. Polymer self-assembly is an efficient way toward various nanostructures including nanotoroids and chiral nanostructures. However, currently, there is no report regarding chiral toroidal nanostructures by self-assembly of polymers. Recently, the group of Prof. Lin Jiaping and Prof. Cai Chunhua from East China University of Science and Technology has reported that a binary system containing polypeptide homopolymer and its block copolymer can self-assemble into uniform chiral nanotoroids in solution. In such a unique structure, the homopolymers aggregate into fibrils and then convolve into a toroidal template, resembling the toroidal condensation of DNA. While the block copolymers self-assemble on the homopolymer toroids forming helical surface nanopatterns, the chirality and width of the surface helical patterns can be varied by the chirality and molecular weight of the polypeptide block copolymers. Their work not only proposes a novel route toward uniform nanotoroids, but also provides a new strategy constructing chiral nanopatterns on the surface of toroids.
