Figure 4. Crosslinking and degradation of PEGNB, PEGNBCA, and PEGNB-X hydrogels.

Figure 4.

(A) Schematic of PEGNB-X synthesis. (B) Initial shear moduli of hydrogels crosslinked by 4 wt% PEGNBCA, PEGNB-D, PEGNB-T, and PEGNB-I with DTT. (C) Degradation of PEGNB-X hydrogels at 37°C by shear moduli changes (G’/G’0) and swelling ratio (Q). Curve fittings represent pseudo first order ester hydrolysis kinetics. (D) Parameters of pseudo-first order hydrolytic degradation kinetics. Al hydrogels were crosslinked by DTT (R = 1) with 1 mM LAP and 2 min 365 nm light exposure (5 mW/cm2).
