FIELD: nanomaterials.
SUBSTANCE: invention relates to nanomaterials, specifically to magnetoactive composites containing nanosized metal particles stabilized by a hyperbranched polymer matrix. Disclosed in invention composite consists of core, which is cobalt nanoparticles, shells – cobalt oxides, which are in a matrix of hyperbranched polyether polyol. Polydispersity coefficient of the polyether polyol does not exceed 1.3. Individual particles have a spherical shape and have a diameter of not more than 30 nm.
EFFECT: proposed invention enables to obtain a polymer-composite composition containing cobalt nanoparticles, having biocompatibility, antimycotic and antiprotease activity.
