METHOD FOR OBTAINING SYSTEMS BASED ON BETA ZEOLITE AND NANOSCALE CERIUM DIOXIDE WITH ANTIMICROBIAL PROPERTIES Russian patent published in 2022 - IPC A61K33/244 A61K33/06 A61L2/23 C01F17/235 B82Y40/00 A61P31/02 A61P31/04 

FIELD: medicine.

SUBSTANCE: invention relates to the production of antimicrobial agents and can be used in medicine as an additive in antimicrobial ointments, wound dressings, anti-inflammatory drugs, etc. The method for obtaining CeO₂-Beta systems with antimicrobial properties in the dark at a concentration of CeO₂ in the system of 30-70% consists in obtaining a reaction mixture by solid-phase mixing of the reagents Ce(NO₃)₃×6H₂O and zeolite Beta, followed by annealing of the resulting mixture for 1 hour at a temperature of 420°C. At the same time, the resulting system has a Beta structural basis and a functional basis: nanoscale CeO₂.

EFFECT: invention makes it possible to obtain a CeO₂-Beta system exhibiting high bactericidal properties against the conditionally pathogenic gram-negative bacterium Pseudomonas aeruginosa (blue pus bacillus) in the dark, as well as to simplify the process of obtaining CeO₂-Beta systems, significantly reducing the number of stages and reagents used.
