Researchers develop hierarchically self-assembled homochiral helical microtoroids

Chirality is essential for life, which can be observed in biological systems hierarchically from the molecular level to macromolecules and higher ordered nanostructures, such as 3D enzymes and micrometer cell membranes. Chirality is precisely controlled within these hierarchical architectures so that a series of life processes can enantio-selectively proceed. Although molecular self-assembly is widely used to fabricate nano/microstructures, a precise chirality control from small molecules extending to micrometer-scale assemblies with satisfied dispersity and homochirality is still a challenge.
