Figure 4. In vitro sealing properties of hybrid hydrogels composed of GelMA (20% w/v) and varying concentrations of AlgMA.

Figure 4.

(a) Images showing the burst pressure assessment of double-network hybrid hydrogels prepared via successive photochemical and ion-mediate crosslinking, (b) representative pressure-time curves obtained from the burst pressure tests, and (c) the burst pressure values of hybrid hydrogels containing varying AlgMA concentrations. (d) Wound closure assessment setup, (e) representative stress-strain curves from wound closure experiments, (f) wound closure strength, (g) and adhesion energy of hybrid hydrogels. Data are reported as the mean values of at least 5 experiments ± their standard deviation. The statistical analysis was done according to the methods explained in “Statistical analysis” section. Asterisks show the results that are statically significant with p-values less than 0.05 (*), 0.01 (**), 0.001 (***), or 0.0001 (****).
