中文摘要：

聚乳酸与多糖都是生物可降解、生物相容性材料，将聚乳酸的力学性能优越性和多糖的生物学优越性能综合利用起来，设计生物仿生材料是一种制备生物医用材料的新手段。文中综合讨论了聚乳酸与多糖接枝改性的最新研究进展，同时对于这类生物仿生材料目前存在的问题以及前景进行了评估。

英文摘要：

The tendency of biomedical materials is to design the novel biomaterials by biomimetic or bioinspired methods. Both polylactide and polysaccharides are biodegradable and biocompatible, and they are extensively applied in tissue engineering or drug delivery system. It is a novel method to design the biomedical materials by combining the polymeric characteristics of polylactide with the biogieal properties of polysaccharides. This paper reviewed the new research in polylactide grafted polysaccharides and commented on the questions and the prospect of the bioinspired materials.
