A matrix material which consists of a copolymer of a carbohydrate and a pharmaceutically acceptable carboxyl group-containing component. Furthermore, a process for the preparation of such a matrix material, in which the pharmaceutically acceptable carboxyl group-containing component is polymerised within a carbohydrate polymer. Finally, the use of the matrix material as a contrast medium or for cell separation, or as a carrier of biologically active substances for depot systems, or for drug targeting. |
