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 4):
The nanocapsule of  claim 1  wherein the shell of said capsule is covered by ultrathin polyelectrolyte film consisted of biocompatible polyelectrolyte 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.
