(a) Cyclic water uptake; (b) Swelling kinetics; and (c) Biodegradation degree of bioscaffolds up to four weeks; (d) SEM images of polydopamine coated-cryogel bioscaffold before and (e) after hydration-dehydration process. Significant differences: *p < 0.05, difference between uncoated- and polydopamine coated-cryogel bioscaffolds. (Unpaired student’s t test).
