In situ photorheology of 10% GelMA-DDS hydrogels for the first 500 s of the crosslinking reaction. (A) Storage modulus. (B) Crosslinking reaction rate. (C) Maximum crosslinking reaction rates. Photocrosslinking with 0.5 mg/mL Irgacure 2959 at 365 nm. n = 5 samples for all groups. Error bands indicated the standard deviation for A and B. For C, symbols indicate statistical differences compared to the control group without cefazolin (* p < 0.05, *** p < 0.001, **** p < 0.0001).
