Investigation of Bio-mimetic synthesis SH/KGM/HAP Scaffold

摘要

Sodium hyaluronate / konjac glucomannan (SH/KGM) porous scaffolds were prepared via blending sodium hyaluronate and konjac glucomannan. The ammonia was used as cross-linker in blending process. The SH/KGM scaffolds were soaked into calcium nitrate solution and then followed by immersing into simulated body fluid to get SH/KGM/HAP porous scaffolds. X-ray diffraction and fourier transform infrared spectroscopy (FTIR) were used to characterize the crystallization and chemical structure of SH/KGM and SH/KGM/HAP scaffold materials. The scanning electron microscope (SEM) was used to analysis the morphology of SH/KGM/HAP scaffold and BMSCs on surface of the scaffold. The results show that hydroxyl-apatite produced on the surface of the SH/KGM, which appears as spherical particles in the SH/KGM/HAP scaffold surface, and the SH/KGM/HAP porous scaffold possesses good biocompatibility with cell.
