A method for preparing liposomes by (1) mixing together an aqueous solvent, a surfactant including a hydrophilic terminal and a C¿2-16? hydrocarbon chain, a sterol and/or a membrane protein, and/or a product to be encapsulated, to dissolve the sterol and/or the product to be encapsulated; (2) mixing the resulting composition with a lipid surfactant to form a uniform lamellar liquid crystal phase or a liquid crystal phase suspension in water; and (3) converting the liquid crystal phase or liquid crystal phase suspension into liposomes.

La présente invention concerne un procédé de préparation de liposomes comprenant: 1) le mélange d'un solvant aqueux, d'un tensioactif comprenant une tête hydrophile et une chaîne hydrocarbonnée en C2 à C16, d'un stérol et/ou une protéine membranaire et/ou d'un produit à encapsuler de façon à obtenir une dissolution du stérol et/ou du produit à encapsuler; 2) le mélange de la composition ainsi obtenue avec un tensioactif lipidique de façon à former une phase cristal liquide lamellaire homogène ou une suspension de phase cristal liquide dans de l'eau; et 3) la transformation de la phase cristal liquide ou de la suspension de phase cristal liquide en liposomes.
