CA 2374577

A matrix comprising: a) a polymeric base matrix comprising macropores (pore system 1) and b) an interior material, possibly porous (pore system 2), retained within the macropores. The matrix is characterized in that there is a continuous free volume between the interior material and the pore walls of the macropores. A method for manufacturing a matrix comprising a base matrix having macropores in which an interior material is located. The method is characterized in comprising the steps: (i) providing a base matrix having macropores; (ii) filling the macropores with a soluble form of the interior material; (iii) transforming the insoluble form to an insoluble form; (iv) shrinking the insoluble form; and (v) irreversibly stabilising the material in its shrinked form. The matrix can be used in separation methods, cell culturing, solid phase synthesis of organic molecules, and in catalytic reactions (such as enzyme reactions) and other uses in which porous support matrices are used.

L'invention porte sur une matrice comprenant a) une base polymère constituée de macropores (système poreux 1), et b) une substance interne éventuellement poreuse (système poreux 2) et retenue dans les macropores. La caractéristique de cette matrice est un volume libre continu se trouvant entre la substance interne et les parois poreuses des macropores. L'invention porte également sur un procédé de fabrication d'une matrice comprenant une base constituée de macropores dans lesquelles se trouve la substance interne. Ce procédé se caractérise en ce qu'il consiste à : (i) former une matrice de base constituée de macropores ; (ii) remplir les macropores d'une forme soluble de la substance interne ; (iii) transformer la forme soluble en une forme insoluble ; (iv) rétracter la forme insoluble ; et (v) stabiliser de manière irréversible le matériau sous sa forme rétractée. Cette matrice à support poreux peut être utilisée dans des procédés de séparation, la culture cellulaire, la synthèse en phase solide des molécules organiques et dans les réactions catalytiques (telles que réactions enzymatiques) et autres utilisations.
