FIELD: nanotechnologies.
SUBSTANCE: invention relates to the field of nanotechnology, in particular to a process for preparing nanocapsules, and describes a method for preparing nanocapsules of a biopag-D preparation in a shell of sodium alginate. Process is characterized in that 0.01 g of E472c is added to the suspension of sodium alginate in isopropanol as a surfactant, then the resulting mixture is stirred with a magnetic stirrer, after which 1 g of biopag-D powder is added, then 5 ml of hexane is added, the resulting suspension of nanocapsules is filtered off and dried at room temperature, the mass ratio of the core: the shell is 1:1, or 1:3, or 1:5 in nanocapsules.
EFFECT: method provides a simplification and acceleration of the process of obtaining nanocapsules, a reduction in losses in the preparation of nanocapsules and can be used in veterinary medicine.
