The thermosensitive hydrogel was prepared by embedding β-cyclodextrin into chitosan/αβ-glycerol phosphate system. The optimal parameters were that the ratio of CS/β-CD was 2/1 (w/w) and the ratio of CS-β-CD/αβ-GP was 9.0/1.0 (v/v), where the gelation time was less than 3min. The hydrogels had obvious lamellar structure, self-comparability, fractal characteristic and had good sustained release efficiency...
