- 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 Gd 3+ 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.
