For years scientists have been exploring the design of particles that can self-assemble into complex superstructures. Such colloidal assemblies can serve as photonic sensors or model systems to understand molecular processes. Taking inspiration from atoms, where valence directs the assembly of well-defined molecules, we expect that anisotropic colloids that can interact directionally will broaden the diversity of colloidal assemblies accessible. This concept is known as patchy particles. Unlike isotropic colloids which mostly yield compact assemblies, patchy particles can direct the formation of new architectures controlled by the physical and chemical interactions between their patches. Several studies validated this concept showing that patchy particles yield new colloidal assemblies. Despite considerable work on the synthesis of patchy colloids, the rational design of particles with multiple addressable patches remains elusive.
