Abstract:
The invention relates to biocompatible polysaccharide-based nanocapsule templated on oil core of diameter not exceeding 1 μm, stabilized without low molecular weight surfactants. The nanocapsule shows long-term stability in an aqueous suspension and is able to highly efficient encapsulation of hydrophobic compounds.

Claim (Index 10):
The process of  claim 7  wherein said nanocapsules are covered by ultrathin polyelectrolyte films obtained by layer by layer technique relying on consecutive adsorption of oppositely charged polyelectrolytes, wherein biocompatible polysaccharide or its derivative of natural origin selected from among chitosan, dextran, starch, hydroxypropyl cellulose, and glycosaminoglycans (e.g. hyaluronic acid, heparan sulfate, heparin sulfate, keratan sulfate, chondroitin sulfate, dermatan sulfate) and synthetic polyelectrolytes selected from among poly-L-lysine, polyornityne, poly (D-glutamic acid), derivatives of poly(lactic acid), polystyrenesulfonate, poly (diallildimethylammonium chloride), polyallylamine hydrochloride or polyethyleneimine at concentration ranging between 0.1 g/L to 30 g/L and ionic strength varying from 0.001 to 3 M are used.
