Storage (G′, closed symbols) and loss (G″, open symbols) moduli for alginate hydrogels. a) Representative rheological data showing all samples for alginate + F68 hydrogels over the entire frequency range. b) Rheological data indicates a significant increase in hydrogel stiffness following autoclaving. Autoclaving the hydrogels while submerged in 0.1M CaCl2 significantly increases the stiffness of the hydrogel formulation. A greater difference between the G″ values was measured over the frequency range of 0.01 to 100 Hz for autoclaved hydrogels with F68 (*) and without F68 (Δ) compared to untreated hydrogels (○ and ☐).
