FIELD: nanotechnology.
SUBSTANCE: sodium hydrogencarbonate is added to sodium alginate suspension in petroleum ether with the presence of E472c as a surface-active substance during agitation of 1,200 rpm, then, 5 ml of carbon tetrachloride is added, whereupon, the core:shell mass ratio is 1:1, 1:2, 1:3 or 1:5 on conversion to dry substance; the obtained suspension is filtered and dried at room temperature.
EFFECT: nanocapsules manufacture process simplification, reduction of losses in the nanocapsules production, acceleration and weight yield increase.
