【摘要】 壳聚糖因活泼基团氨基和羟基的存在,可以引入不同基团进行化学改性,生成的多种不同衍生物因具有良好的生物相容性、生物降解性、吸湿保湿性等特点,被广泛地应用于医药领域。就近年来壳聚糖常见的几种化学改性方法及其衍生物在医药领域的应用进展进行综述。更多还原

【Abstract】 Different groups of chitosan could be introduced for chemical modification to generate various derivatives due to the existence of active amino and hydroxyl group. Further more,the derivatives has a number of unique properties such as biocompatibility,biodegradability,moisture-absorption and moisture-retention abilities and so on,which enable them to have wide application in medical fields. In this aticle,some correlative literatures of both inside and outside country was summarized to review the progress in chemical modification of chitosan,and application of its derivatives in medical fields recently.更多还原
