Self-assembled molecules spontaneous curvature

Self-assembly is the spontaneous, noncovalent association of two or more molecules under equilibrium conditions into stable, well-defined aggregates. In nature, self-assembly is a ubiquitous strategy responsible for the formation of cell membranes, double-stranded nucleic acids, and viruses. In chemistry, self-assembly offers a rapid way to construct receptors, catalysts, and materials. With appropriate curvature and careful positioning of self-complementary bonding sites, self-assembling systems generate capsules.
