Uni-axial unconfined compression experiments were conducted on photocrosslinked HA-MA hydrogels. The effect of polymer concentration (w/v), molecular weight, degree of modification (DOM), and light source were evaluated. (A) UV (10 minute terminal crosslinking time) and (B) green light (20 minute terminal crosslinking time) crosslinked HA-MA hydrogels consisted of low, medium, and or DOM and HA-MA concentrations of 2, 3 or 4% (w/v). Results are shown as average ± standard deviation, n = 5.
