FIELD: medicine, pharmaceutics.
SUBSTANCE: invention relates to chemical-pharmaceutical industry, veterinary, agriculture and represents method for obtaining water-based suspension of copper nanoparticles for external application, characterised by the fact that ultrasonic dispersion of copper nanoparticles is realised for 30 min with frequency 35 Hz with water solution of catholyte with parameters: Eh=-300 mV, pH 7-8, stabilised with amino acid threonine in amount not less than 0.01 wt % at temperature not higher than 40°C.
EFFECT: invention makes it possible to obtain in a stably biologically active suspension of preparation of copper nanoparticles, which does not produce toxic effect.
