FIELD: medicine.
SUBSTANCE: invention is characterised by that produced bactericidal water-dispersion solution consists of silver nanoparticles, surface-active substance (SAS) and water with size distribution of particles. The second subject is production method of this solution by silver ion restoration in reciprocal micelle system including preparation of SAS micelle solution in nonpolar solvent from: n-hexane, or n-heptane, or n-octane, or n-decane, or cyclohexane, or isooctane with reducing agent added. Aqueous silver salt solution is prepared with ammonia solution. Produced two-phase system is settled with following aliquation and separation of organic layer of base aqueous silver nanoparticles solution of reducing agent from group flavonoids, e.g. quercetin.
EFFECT: enables production of high effective bactericidal agent with high biological activity associated with microorganisms which keeps for a long time.
