Rheological characterisation of 3.2 mg/mL bovine Col1 (circles) and 3.2 mg/mL bovine Col1, 0.5 mg/mL HA (squares) hydrogel formats by (A) frequency sweep, (B) amplitude sweep and (C) flow sweep analysis. (A) Frequency analysis determined the ratio of loss and storage moduli across increasing angular frequency. (B) Amplitude analysis determined the linear viscoelastic range of the hydrogels (dashed vertical line indicates visco-elastic limit of both hydrogel formats). (C) Flow analysis determined “flowing” properties of the hydrogels under increasing stress. Mean +/− standard deviation. All series, n = 3.
