Figure 1. — Characterization of CH/GP/Cur hydrogel. Scanning electron micrographs of (A) the inner structure and (B) surface morphology of the lyophilized CH/GP/Cur hydrogel (magnification, ×200); (C) A photo showing the temperature-triggered sol (left, room temperature) to gel (right, 37°C for 10 min) transition; (D) in vitro curcumin release behavior of CH/GP/Cur; (E) in vitro degradation profile of CH/GP/Cur; (F) rheological analysis of the CH/GP/Cur solution; the arrow head indicates the transition point where G' (elastic modulus) outweighs G' (viscous modulus). CH/GP/Cur, chitosan/β-glycerophosphate-β-cyclodextrin-curcumin.
