Abstract
This brief review covers the effect of small-size gold nanoparticles on cholesteric liquid-crystalline dispersions formed by double-stranded high-molecular-weight DNA molecules. It is shown that, as in the case of liquid crystals formed by low-molecular-weight compounds, this effect results in the nematization of the spatial structure of the dispersion particles and the incorporation of small-size gold nanoparticles in the “free” space between DNA molecules, forming quasinematic layers of dispersion particles. As a result of these processes, an “integrated” structure (“rigid” spatial DNA structure) is formed, which possess unique properties.
