Calcium Ion Treatment Behavior of Silk Fibroin/Sodium Alginate Scaffolds
The silk fibroir/sodium alginate scaffolds were prepared using lyophilization method.And then,the blend scaffolds were treated with calcium ions.The morphology of the blend scaffolds exhibited a thin layer structure before calcium ions treatment,and much more rod-like structure appeared at the layer surface with adding the increase content of sodium alginate in the blend scaffolds.After calcium ions treatment,much more rod-like structure disappeared after adding 30%sodium alginate or more in the blend scaffolds.Wide angle X-ray diffraction and Fourier transform infrared analysis results confirmed the crystal structure of silk fibroin was not influenced by adding the different content of sodium alginate,exhibiting the silk Ⅰ and silk Ⅱ structure co-existed in the blend scaffolds.And the same time,the average mass loss value of the blend scaffolds was higher than the pure silk fibroin scaffold,reaching 9.884%,11.2%,and 8.626%,respectively,when the blend scaffolds contained 10%,30%,and 50% sodium alginate,respectively.Thus,the silk fibroir/sodium alginate scaffolds should be a useful biomaterial applicable for a wide range of tissue engineering.
