Comparison of viscoelastic properties for PEG-CMP9-K and PEG-RCMP-K hydrogels (10 wt%). (A) and (B) Storage (G′) and loss (G″) moduli of the two hydrogels as a function of frequency with phase angle shown in the inset. (C) Storage (G′) and loss (G″) moduli at ω = 7.5Hz (PEG-RCMP-K crossover frequency) with data reported as mean ± SEM error bars (n ≥ 4). (D) Ensemble-average MSDs and storage moduli G′ (at ω = 30 Hz) of PEG-CMP9-K, PEG-RCMP-K, and PEG-CMP9-K after free CF-CMP9 addition.
