Metal and metalloid nanopartilces stabilized by (bio)polymers: spectral and structural-morphological characteristics

A comparative study of the spectral and structural-morphological characteristics of the metal (copper, silver) and metalloid (selenium) containing nanodispercions based on biocompatible water-soluble stabilizers: bovine serum albumin, random copolymers of 2-deoxy-2-methacrylamide-D-glucose or 4-acryloyl-morpholine with 2-dimethylaminoethyl-methacrylate was carried out by means of the UV-spectroscopy, atomic-force and transmission electronic microscopy. Effect of the nature of the nanoparticle as well as polymeric stabilizer on the spectral and structural-morphological characteristics and mechanism of formation of the nanostructures/nanoparticles was shown. It has been established that structures with different organization of the organic phase around nanoparticles are formed in the studied nanodispersions. It has been shown that for the studied polymer carriers, metal-containing nanostructures/nanoparticles have smaller dimensions than metalloid-containing systems.
