Synthesis and biochemical characteristics of AL–HA–Tyr hydrogels. (A) Synthesis of tyramine functionalized HA (HA–Tyr). (B) AL–HA–Tyr hydrogel formation. (C) Characterization of HA–Tyr hydrogel. Left: morphology of HA–Tyr after lyophilization. Center: HA dissolved in distilled water. Right: HA–Tyr hydrogel formation catalyzed by HPR and H2O2. (D) Cumulative release of AL from free AL, and AL–HA–Tyr + lysozyme-25 (n = 3). (E) Factors affecting gel formation. Gelation points of HA–Tyr conjugates at different concentration of H2O2 and HRP (n = 6). All data are shown as means ± SD.
