title: [Complexes of gadolinium with linear and liquid-crystalline forms of DNA].
abstract: The binding of Gd3+ ions to linear double-stranded DNA molecules in water-salt solutions or in liquid-crystalline dispersions is accompanied by sharp changes in their optical and X-ray characteristics. Depending on the initial conditions of complex formation, the binding of Gd3+ ions either to DNA bases or phosphate groups occurs, which leads to changes in the properties of the liquid-crystalline dispersions. The packing of neighboring DNA molecules in particles of the liquid-crystalline dispersion of the complex DNA-Gd3+ depends strongly on the concentration of Gd3+ ions. This process is accompanied by a decrease in the amplitude of Bragg's reflection maximum. The unique properties of the developed material open the possibilities for its practical use.
