| Outline of Final Research Achievements |
Chitosan is a polycation and can form the polymerized membranes by the reaction with polyanions. We prepared the chitosan-silicate hybrid membranes via the sol-gel process. Their wettability, mechanical properties, and degradability were controllable by the density of cross-linking between the amino groups of the chitosan chains and the epoxy groups of GPTMS. Moreover, the hybrid membranes had excellent cytocompatibility for various cells, such as osteoblastic cells, fibroblast cells, and human gingival cells. In this study, the capsules were prepared from the chitosan-GPTMS hybrids precursor sol for the controllable releasing by the crosslinking of the chitosan matrix. And then, the capsules were modified by hydroxyapatite to improve their mechanical properties. The drug model was injected by micro manipulation methods.
