chemical and enzymatic hydrolytic release of dexamethasone from HA-DXM conjugates (A) and PEG-bis-AP/HA-DXM semi-IPNs (B). HA-DXM conjugates and PEG-bis-AP/HA-DXM semi-IPNs were incubated in PBS (pH 7.4) buffer, PBS (pH 7.4) buffer with esterase (Ease), and PBS (pH 7.4) buffer with Ease and hyaluronidase (Hase) (5 units/ml each). The concentration of released dexamethasone was measured by ELISA.
