摘要: A stable phase of toroidal, or ringlike, supramolecular assemblies was formed by combining dilute solution characteristics critical for both bundling like-charged biopolymers and block copolymer micelle formation. The key to toroid versus classic cylinder formation is the interaction negatively charged hydrophilic an amphiphilic triblock with a positively divalent organic counterion. This produces self-attraction cylindrical micelles that leads formation, mechanism akin toroidal semiflexible such as DNA. toroids can be kinetically trapped chemically cross-linked. Insight into gained observation intermediate structures during film casting.
