FIELD: medicine; pharmaceuticals. SUBSTANCE: invention refers to pharmaceutics and can be used to produce a carrier system for targeted drug delivery in diagnostics or therapy. Disclosed is a carrier system for targeted delivery of penicillin and anthracycline-based antibiotics based on nanopowders, having magnetic properties, characterized by that it consists of amorphous nanopowder of silicon dioxide doped with manganese dioxide, wherein doping with manganese dioxide is carried out in the process of producing nanopowders by evaporation with a pulsed electron beam in a low pressure gas, and has a porosity of up to 0.88 cm3/g and specific surface area of up to 176 m2/g. EFFECT: disclosed carrier system has high porosity and specific surface area, which determines high loading capacity, magnetic properties, which enable to control the drug delivery process, and biocompatibility.
