Table 1 Overview of hydrogel composition and physical characteristics; nMA is the amount of MA moieties in 1 gram of gelatin precursor; nAATIPA is the amount of AATIPA incorporated in the hydrogel determined by elemental analysis; GF is gel fraction, G’ is the storage modulus of the hydrogel films, SR is the swelling ratio of the porous scaffolds, Iswollen is the calculated content of iodine in the swollen hydrogels, and vsound is the sound velocity within that hydrogel sample at 2 MHz. The SD values were evaluated based on three independent measurements (N = 3)
