Abstract
(EN)
A polymeric gel matrix for enclosing, retaining and releasing a substrate, said polymeric gel matrix containing: at least one gelation agent forming a first component of the polymeric gel matrix; and at least one de-gelation agent forming a second component of the polymeric gel matrix; the at least one gelation agent for enclosing and retaining the substrate in the polymeric gel matrix; the at least one de-gelation agent for breaking down the polymeric gel matrix resulting in the release of the substrate from the polymeric gel matrix.
(FR)
La présente invention concerne une matrice de gel polymère pour enfermer, retenir et libérer un substrat, ladite matrice de gel polymère contenant: au moins un agent de gélification formant un premier composant de la matrice de gel polymère; et au moins un agent de dégélification formant un second composant de la matrice de gel polymère; l'agent ou les agents de gélification pour enfermer et retenir le substrat dans la matrice de gel polymère; l'agent ou les agents de dégélification pour décomposer la matrice de gel polymère conduisant à la libération du substrat hors de la matrice de gel polymère.
