Structure formation in soft nanocolloids

The packing of polymeric nanocolloidal particles remains an interesting open problem in the physics of soft condensed matter. The common feature of dendrimer micelles, star polymers, spherical polymer brushes, diblock copolymer micelles is that in dense suspensions, they deform so as to fill space. In terms of structure, the thus formed ordered phases are generally quite different from elemental solids as witnessed, e.g., by the frequent occurrence of the A15 lattice and quasicrystals in monodisperse systems. We will review some of the experimental results in the field and outline a few coarse-grained, particle-level models proposed to describe clustering, exotic crystal lattices, and quasicrystals as well as microscopic elasticity of such particles.
