Title
(EN) CONTINUOUS PROCESS FOR COATING LIPOSOMIAL VECTORS WITH POLYMER
(FR) PROCÉDÉ CONTINU DE REVÊTEMENT DE VECTEURS LIPOSOMIAUX PAR UN POLYMÈRE
Abstract
(EN) The invention relates to a continuous or semi-continuous, and therefore rapid and highly productive, process for obtaining nanoliposomes completely coated with chitosan, a biocompatible natural polymer able to increase their stability and mucoadhesive properties. The process uses a highly productive "simil-microfluidic" technique for the polymeric coating of nano-vectors. The invention also relates to the chitosan-coated nanoliposomes or nanostructures which may be obtained through the concerned process, as well as to pharmaceutical, nutraceutical, cosmetic, personal hygiene, food or coloring products containing them.
(FR) L'invention concerne un procédé continu ou semi-continu, donc rapide et hautement productif, permettant d'obtenir des nanoliposomes complètement revêtus de chitosane, un polymère naturel biocompatible pouvant augmenter leur stabilité et leurs propriétés muco-adhésives. Le procédé met en œuvre une technique « simili-microfluidique » hautement productive pour le revêtement polymérique de nano-vecteurs. L'invention concerne également les nanoliposomes ou nanostructures revêtus de chitosane qui peuvent être obtenus au moyen du procédé concerné, ainsi que des produits pharmaceutiques, nutraceutiques, cosmétiques, alimentaires, d'hygiène personnelle ou de coloration les contenant.
