Figure 6. In vitro degradation of PPEGMC.

Figure 6

A) Mass loss of the photocrosslinked PPEGMCs and redox crosslinked (PPEGMC-Redox) hydrogels incubated in PBS (pH 7.4; 37° C) for up to 1 30 days; B) Mass loss of the photocrosslinked PPEGMC 6/4 crosslinked with 1.5, 3, and 6 v/v% of crosslinkers; SEM image of the degrading PPEGMC6/4 film at C) day 5, D) day 10, and E) day 20. PPEGMC exhibited smooth surface at day 5 and gradually turn into porous matrix over time. All scale bar = 200 µm.
