Synthesis and characterization of DexMA and MeCD. (A) Schematic of methacrylated cyclodextrin (MeCD, top, purple) and methacrylated dextran (DexMA, bottom, blue) synthesis through esterification with GMA. (B) DS and yield dependence on the molar feed ratio of GMA to glucose repeat units. (C) Hydrogels are formed through copolymerization of MeCD and DexMA. Representative oscillatory time sweeps (1 Hz, 1.0% strain) of photopolymerization (10 mW/cm2, 5 min as indicated by the shaded area) showing shear moduli (G′) of MeCD alone (D), DexMA alone (E), and their combination (F).
