A method of modifying the polyelectrolyte shells CAPSULES magnetite nanoparticles

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method of modifying envelopes of polyelectrolyte capsules with magnetite nanoparticles. The disclosed method involves producing a container matrix in form of porous calcium carbonate microparticles, forming envelopes of polyelectrolyte capsules by successive adsorption of polyallyl amine and polystyrene sulphonate and modifying with magnetite nanoparticles on the surface of the container matrix or after dissolving the matrix through synthesis of magnetite nanoparticles via chemical condensation.;EFFECT: invention enables to obtain modified polyelectrolyte capsules, designed to deliver medicinal substances which do not harm the human body.;3 cl, 4 dwg, 1 ex
