摘要：

Selenium-containing biogenic nanosized systems based on polymer stabilizers (PSts) of different natures are obtained. A comparative investigation of the kinetic parameters of self-organization and the dimensional characteristics of forming nanostructures and their shapes is performed by means of light scattering, UV spectrophotometry, atomic force microscopy, and small angle X-ray scattering. The effect of the nature of PSts on the structural and morphological parameters (hydrodynamic radius, mean-squared radius of gyration, selenium core radius, and density) of selenium-containing nanostructures is established.
