Progress on amphiphilic polysaccharide self-assembly micelle delivery system / 中国生化药物杂志

Natural polysaccharides are a kind of hydrophilic polymers.By grafting hydrophobic moieties to the polysaccharide backbone,could form self-assembled micelle with core-shell structure in aqueous by undergoing intramolecular or intermolecular association between hydrophobic moieties.The self-assembly micelles of amphiphilic polysaccharides provides a positive outlook for drug delivery systems with biodegradability,low antigenicity,good biocompatibility and so on.This review focus on biological activity of amphiphilic polysaccharide as self-assembly carriers,the principle of self-assembly of polymeric micelles,and the recent progress in hydrophobic modification of natural polysaccharides.
