This review examines host-guest interactions in cyclodextrin hydrogels for wound healing and tissue regeneration, suggesting advancements in their clinical application.
Cyclodextrins (CDs), cyclic oligosaccharides formed by α-1,4-glycosidic-bonded D-glucopyranose units, feature unique hydrophobic cavities and hydrophilic exteriors that enable molecular encapsulation via host–guest interactions. CDs form supramolecular host–guest complexes with diverse molecular entities, establishing their fundamental role in supramolecular chemistry. This review examines fabrication strategies for CD-based supramolecular hydrogels and their applications in tissue engineering and regenerative medicine, with focused analysis on wound healing, corneal regeneration, and bone repair. We critically analyze CD–guest molecular interaction mechanisms and innovative therapeutic implementations, highlighting the significant potential of CD hydrogels for tissue regeneration while addressing clinical translation challenges and future directions.
