METHOD OF PRODUCTION OF ANTIBIOTIC NANOCAPSULES IN AGAR-AGAR Russian patent published in 2015 - IPC A61K9/51 B82B1/00 B01J13/06 A61K31/00 

Abstract RU 2560663 C1

FIELD: nanotechnology.

SUBSTANCE: invention describes a method of production of antibiotic nanocapsules by the method of precipitation with nonsolvent, in which into the suspension of 1.5 g of agar-agar, used as a shell of the nanocapsules, in hexane and 0.01 g E472s as a surfactant, 0.5 g of the antibiotic powder is added in small portions, then 5 ml of acetonitrile as the precipitant is added dropwise, then the resulting suspension of nanocapsules is filtered and dried.

EFFECT: simplification and acceleration of the process of producing the nanocapsules, and increase in the yield by weight.
