Research Abstract |
The preparation process to obtain water-insoluble films of biological polysaccharides was established by hot pressing of polyion complexes made of glycosaminoglycans and chitosan. The optimal condition for each polysaccharide combination was clarified. Effects of structure and molecular weight of polysaccharides on physical properties of the resulting films were evaluated. Hydroxyapatite deposition on these films under body fluid conditions was achieved. To obtain larger sizes of the films rapidly, improvement of the film preparation process was also examined.
