Solven dried polysaccharide sponges |
| abstract |
THE INVENTION PROVIDES METHODS OF PREPARING WATER-INSOLUBLE POLYSACCHARIDE SPONGES, AND SPONGES OBTAINED BY MEANS OF THE METHODS. THE METHODS COMPRISE: (a) PROVIDING AN AQUEOUS SOLUTION OF A SOLUBLE POLYSACCHARIDE; (b) FREEZING THE SOLUTION; (c) TREATING THE FROZEN SOLUTION WITH A WATER-MISCIBLE ORGANIC SOLVENT SUCH AS ISOPROPANOL TO EFFECT SOLVENT EXCHANGE FOR THE WATER IN THE FROZEN SOLUTION; AND (d) DRYING THE RESULTING POLYSACCHARIDE MATERIAL. THE ORGANIC SOLVENT CONTAINS A CROSS-LINKING AGENT SUCH AS CALCIUM CHLORIDE TO RENDER THE POLYSACCHARIDE WATER-INSOLUBLE IN THE SOLVENT-EXCHANGE STEP (c). THE RESULTING MATERIALS ARE MORE CONFORMABLE AND LESS FRIABLE THAN FREEZE-DRIED POLYSACCHARIDE SPONGES. |
