A nematic liquid crystal is an orientationally ordered fluid, which interacts with the surfaces of inclusions. This generates topological defects, which are responsible for structural forces between microparticles . The structural forces in liquid crystals are strong, anisotropic and long range, and are responsible for self-assembly of a variety of colloidal superstructures: 2D colloidal crystals , colloidal wires, assembled by entangled topological defects , superstructures in the mixtures of large and small colloidal particles and a broad variety of 2D nematic binary colloidal crystals.

COBISS.SI-ID: 23559207We show how our experience with simple spherical colloidal particles in nematic liquid crystals that assemble in 1D, 2D and 3D structures can be extended to particles with patterned surface anchoring and to faceted particles. The effect of a patterned surface interaction is illustrated by spherical Janus particles exhibiting planar and homeotropic nematic anchoring on the two hemispheres. We examine also assemblies based on faceted particles where simple geometrical shapes enable formation of well defined lattice structures. Predictions are contrasted with recent experimental studies.
