摘要: Chitosan microspheres with diameter of 14.3-48.5 μm were prepared by emulsion method and using natural vanillin as cross-linking agent. The surface morphology microstructure the characterized scanning electron microscopy, X-ray diffraction Fourier-transform infrared spectroscopy, etc. hollow showed a well-defined spherical shape median 30.3 possessed uniform micro-wrinkles, which is in favor drug release. Interpenetrating network mechanism might result from Schiff base reaction acetalization hydroxyl carbonyl between chitosan vanillin. Berberine, model drug, was loaded released sustainable manner. loading ratio could change 9.16% to 29.70% corresponding entrapment efficiency 91.61% 74.25%. In vitro cell culture study MG63 cells vivo implantation clearly that provide favorable attachment biocompatibility. results confirm drug-loaded vanillin-crosslinked be worthy candidate either carriers drugs cells, or therapeutic matrix for bone repair regeneration.
