  Alginate(SA) and chitosan(CS) are commonly used natural polysaccharides.Their well-known biological properties such as biocompatibility, non-toxicity, non-immune prototype and high hydrophilicity make the two kinds of biomaterials exhibit remarkable performance in tissue engineering.In our work, polyelectrolyte complex scaffolds composed of alginate and chitosan were fabricated by electrostatic interaction between-COO-and-NH3+ groups.Porous structure was achieved through phase separation technique.By varying the molar ratio (-COO-/-NH3+), the scaffolds presented elastic behavior and fatigue durability by cyclic mechanical test in wet state.In vitro, rabbit adipose-derived stem cells (rASCs) culture indicated that more CS content resulted in more adherent cells in the SA/CS scaffolds.

目的:纳米水凝胶因其高亲水性、高比表面积和智能响应性,在药物控释、靶向载体等领域的应用前景广泛.然而,目前纳米水凝胶制备过程中的小分子物质(如引发剂、小分子交联剂、有机溶剂等)具有潜在的细胞毒性,并且制得的凝胶存在粒径可控性差、载药量低等不足.为解决上述问题,本课题通过纳米二氧化硅(SiO2)为模版,在其表面接枝聚L-谷氨酸(PLGA),并以壳聚糖(CS)作为大分子交联剂,构建PLGA/CS化学交
