FIELD: nanotechnology.
SUBSTANCE: invention relates to methods of producing highly dispersed colloidal particles or nanoparticles of metallic silver, which can be used in biotechnology, medicine and veterinary science as part of preparations with antimicrobial action. Described is a method of producing colloidal silver nanoparticles, involving dissolution in water of a medical polymer and a silver salt, reduction of silver ions, wherein for reduction of silver ions obtained solution is subjected to electron-beam treatment by passing through it a beam of accelerated electrons at absorbed dose of 5-30 kGy.
EFFECT: technical result is high antimicrobial activity, low toxicity and high stability of aqueous solution of silver nanoparticles.
