FIELD: nanotechnology.
SUBSTANCE: sodium alginate is used as the nanocapsule coating, and the metal salt is used as the core for the core to shell: 1:3 shell weight ratio, while the metal salt is added to a suspension of sodium alginate in butanol containing the E472c preparation as a surfactant with stirring 1200 rpm, then petroleum ether is poured, the resulting suspension is filtered off and dried at room temperature.
EFFECT: simplification and acceleration of the process of obtaining nanocapsules.
