Mechanically compliant photo-cross-linked Hep-MA primary hydrogel networks. (a) Representative stress–strain plots of Hep-MA₀₅ hydrogels under compression shown along with (b) extracted values for Young’s modulus. (c) Frequency sweeps of Hep-MA₀₅ networks indicated that the storage and loss moduli of gels varied only slightly for ω between 0.1 and 100 rad s^–1. (d) A summary of the values for storage modulus G′ at ω = 100 rad s^–1 is shown for heparin-based networks as a function of [Hep-MA]₀.
