FIELD: nanotechnology.
SUBSTANCE: metal oxides are selected from zinc oxide, copper oxide (I), copper oxide (II), alumina, manganese oxide (IV), titanium oxide (IV), while implementing the method, 1 g of metal oxide is slowly added to suspension of 3 grams of sodium alginate in petroleum ether in the presence of 0.01 g of preparation E472c as a surface-active agent while stirring at 1200 rpm, and core:shell mixing ratio on a dry basis is 1:3, then 5 ml of carbon tetrachloride are added, the resulting suspension is filtered and dried at room temperature.
EFFECT: nanocapsules production process simplification and acceleration, reduction of losses in nanocapsules production.
