| Popis: | 96 Bone tissue engineering utilizes porous biomaterial scaffolds to deliver biofactors including cells, genes, and proteins to regenerate bone. Porous biomaterial scaffolds must fulfill two primary functions to ensure successful treatment of bone defect. The scaffold must have enough porosity in order to deliver biofactors and provide temporary mechanical support. Calcium sulfate has superior biocompatibility and osteoconductivity. It is inexpensive and can be used safely and conveniently in a wide variety of bone defects. But the drawback of porous calcium sulfate is its low strength. This study is about how to increase its strength. This study uses salt-leaching to produce porous calcium sulfate and its compressive strength is about 5MPa. And then this porous scaffold is successively immersed in C solution and G solution in order to form H thin film and increase porous scaffold's compressive strength. |
