ABSTRACT
The properties of nanoconstructions formed by double-stranded DNA molecules fixed in the structure of their liquid crystalline dispersions and cross-linked by nanobridges were described. The dependence of the optical properties of the nanostructures on various factors (DNA concentration, nanobridge components, etc.) was examined.

The formation of liquid-crystalline dispersions from DNA-chitosan complexes in polyethyleneglycol-containing solutions was studied. It was shown that the molecular crowding affects neither the efficiency of binding of chitosan molecules to DNA nor the mode of spatial packing of DNA-chitosan complexes in particles of liquid-crystalline dispersions.
