description: This work is devoted to the development and optimization of the synthesis method of antibacterial granular polymers based on biocompatible 2-hydroxyethyl methacrylate (HEMA) and ethylene glycol dimethacrylate (EGDMA) containing triple nanocomplexes "Bi - Î²-cyclodextrin (Î²-CD) nanoparticles - poly-N-vinylpyrrol (PVP) ". It was shown that steric stabilization of bismuth nanoparticles was carried out by distributing polyvinylpyrrolidone molecules on the surface of a complex of nanoparticles with Î²-cyclodextrin. The stability of the ternary complexes was maintained for 20 days. Using the methods of spectrophotometry, dynamic light scattering and X-ray analysis, the formation of aggregatively stable triple nanocomplexes and their incorporation into a polymer matrix is established. The study of antibacterial activity against the strain of Bacillus subtilis showed that the effective bactericidal agent is the triple complex Bi-Î²-CD-PVP with a concentration ratio of Î²-CD / PVP equal to 90 wt% / 10 wt% and its release from the polymer matrix GEMA-EDGMA.
