FIELD: nanotechnology.
SUBSTANCE: metal oxides are selected from aluminium oxide, copper oxide(I), copper oxide (II), manganese oxide (IV), titanium oxide (IV), carrageenan is used as the shell. During the method execution 1 g of the metal oxide is slowly added to the 3 grams carrageenan suspension in petroleum ether in the presence of 0.01 g of the preparation E472c as the surfactant with stirring at 1200 rpm, wherein the core to shell weight ratio is 1: 3 when recalculated to dry matter, then 5 ml of acetone is added as the precipitator, the resulting suspension is filtered off and dried at room temperature.
EFFECT: nanocapsules production process simplification and acceleration, reduction of losses during the nanocapsules production.
