    摘要： A method for the manufacture of a solid porous separation material based on a polysaccharide, said method comprising the steps of: (a) providing an aqueous solution (I) of a polysaccharide, (b) solidifying the solution, preferably by transforming the solution to a gel, and (c) optionally cross-linking the polysaccharide, with the proviso that, if step (c) is present, steps (b) and (c) may be carried out simultaneously. The method is characterised in that the polysaccharide provided in step (a) is modified by being inter-molecularly cross-linked to an extent such that the viscosity of solution (I) is at least 110%, preferably at least 200%, of the viscosity of an aqueous solution (II) of the corresponding polysaccharide which has not been inter-molecularly cross-linked and which is present in the same concentration as the inter-molecularly cross-linked polysaccharide is in solution (I).

    摘要： A matrix including: a) a polymeric base matrix including 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 including a base matrix having macropores in which an interior material is located. The method is characterized in including 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 from to an insoluble form; (iv) shrinking the insoluble form; and (v) irreversibly stabilizing the material in its shrunken 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.
