Abstract: front page image
(EN)The present invention relates to hydrogels that include: (a) at least one natural polymer supplied with a negative electric charge; (b) at least one molecule that is a natural constituent of the human body able to act as a cationic cross-link of the aforementioned polymer or polymers. The invention likewise relates to use of same in medicines or health products; in tissue engineering or regenerative medicine; in cosmetic, hygiene or nutritional applications and in surface coatings. The invention also relates to methods for preparing same.
(ES)La presente invención se refiere a hidrogeles que comprenden: (a) al menos un polímero de origen natural dotado de carga eléctrica negativa; (b) al menos una molécula constituyente natural del organismo humano capaz de actuar como reticulante catiónico del polímero o los polímeros anteriores. Al uso de los mismos como medicamentos, productos sanitarios o en ingeniería de tejidos o medicina regenerativa, o con aplicaciones cosméticas, de higiene, nutricionales y de recubrimiento de superficies así como a procedimientos para su preparación.
(FR)La présente invention concerne des hydrogels qui contiennent: (a) au moins un polymère d'origine naturelle doté d'une charge électrique négative; (b) au moins une molécule constituant naturel de l'organisme humain pouvant agir comme réticulant cationique du polymère ou des polymères antérieurs. Elle concerne également leur utilisation comme médicaments, produits sanitaires ou dans l'ingénierie des tissus ou la médecine régénérative, ou avec des applications cosmétiques, d'hygiène, nutritionnelles et de recouvrement de surfaces, ainsi que leurs procédés de préparation.
