Structure and Morphology of Copper- and Selenium-Containing Nanosystems Based on Water-Soluble Polymer Stabilizers of Varying Nature

A comparative study of newly synthesized copper- and selenium-containing nanosystems based on a wide range of water-soluble polymer stabilizers is carried out using atomic force and transmission electron microscopy. Bovine serum albumin, poly-4-acryloylmorpholine, water-soluble statistical copolymers of 2-deoxy-2-methacrylamido-D-glucose or 4-acryloylmorpholine with 2-dimethylaminoethyl methacrylate) are used as polymer stabilizers. The effect of the stabilizer and nanoparticle nature on the structural and morphological characteristics of the nanostructures/nanoparticles and the mechanism of their formation is revealed using copper- and selenium-containing nanosystems as an example. In an aqueous solution of the studied nanosystems, mainly spherical nanostructures/nanoparticles are formed, the size of which is primarily determined by the nature of the nanoparticles: copper-containing nanostructures/nanoparticles have a smaller size than selenium-containing ones.
