We present results of computer simulations of patchy particle “shape amphiphiles” undergoing self-assembly. We show how various measures of anisotropy, including particle shape, patterning, functionalization and interaction selectivity, can be combined and exploited to achieve complex mesoscale one-, two- and three-dimensional structures such as wires, sheets, shells, helices, gyroid, diamond, and other complex structures through self-assembly. We discuss in detail the self-assembly of cone-shaped particles into precision micelles identical to colloidal molecules obtained by droplet evaporation in the limit of small numbers of particles, and identical to icosahedral virus structures for intermediate to large numbers of particles.
