Annotatsiya
Water-soluble nanocomposites with narrow distribution of nanoparticles of pharmacophore bismuth and iron oxides have been obtained. The biopolymer matrix of the arabinogalactan polysaccharide has exhibited strong stabilizing properties with respect to transition metal oxides. The size of the spherical metal oxide nanoparticles has been found of 5–7 nm as per transmission electron microscopy. The exclusion liquid chromatography data have revealed that the change in the molecular mass parameters of arabinogalactan is due to the combined processes of self-assembly of nanocomposites and alkaline decomposition.
