摘要

The properties of the cholesteric liquid-crystal dispersion containing deoxyribonucleic acid (DNA) molecules and gadolinium ions are investigated using the neutron activation analysis. The cholesteric structure of the DNA–Gd complex is formed by double-stranded DNA molecules and Gd3+ cations in nanoparticles. The DNA concentration in nanoparticles reaches 350 mg/ml. The gadolinium concentration in the DNA–Gd complex is determined using the neutron activation analysis. It is found that the DNA–Gd complex contains approximately 1.5 gadolinium atoms per phosphate group of the DNA molecule. The local gadolinium concentration in the nanoparticle reaches 250 mg/ml.
