摘要：With excellent biocompatibility and biodegradability,natural polysaccharides and their derivative s have exhibited great potential in constructing drug delivery ve hicles for tissue engineering and therapeutics.Cucurbit[n]uril(CB[n])-mediated reversible crosslinking of polysaccharides possess intrinsic stimuliresponsiveness towards competitive guests and have been extensively investigated to fabricate various particles and hydrogels for multiple stimuli-re sponsive drug release by incorpo ration with other stimuli including photo,redox,and enzyme.Through host-guest interactions between CB[6]and aliphatic diamines,functional tags covalently connected with CB[6]can be readily anchored into polysaccharidebased hydrogels,realizing multiple functionalization.The rheological prope rty and drug release profile of polysaccharide-based supramolecular hydrogels can be facilely tuned through CB[8]-mediated dyna mic homo or hetero crosslinking of polysaccharides and/or other polymers.In this review,we introduce and summarize recent progress regarding polysaccharide-based supramolecular drug delivery systems mediated via host-guest interactions of CB[6]and CB[8],covering both bulk hydrogels and particular systems.At the end,possible utilization of CB[7]-based host-guest interactions in constructing polysaccharide-based drug delivery systems and future perspectives of this research direction are also discussed.
