Multivalent, multiflavored droplets by design
Abstract
Whereas crystals and other geometrical structures can be self-assembled under equilibrium conditions from a few particles with a few, often simple, identical interactions, functional materials require a multitude of specific interactions between many different types of particles and nonequilibrium, often hierarchical assembly. Here, we introduce a set of building blocks on the colloidal micrometer scale with designed valence and specificity that readily make linear, branched, or other programmed connected networks, yet maintain the flexibility needed to fold, unfold, or restructure from the original backbone. We demonstrate the self-assembly of alternating copolymers, hetero chains, trivalent clusters, and a dynamic programmability by opening and closing chain ends.
