Figure 3.

Swelling, degradation, contact angle, and mechanical characterizations of assembled membranes. (A) The swelling capacity of all membranes at different time points for 24 h (n = 3). Note a higher swelling for GelMA pure and TCP-incorporated membranes. (B) Degradation profile of all membranes at several time points (n = 3). Note an almost complete degradation for pure GelMA membranes after 28 days. (C) Averaged contact angle measurements (n = 3); different lowercase letters denote statistical differences between groups. (D) Individual contact angle data over time points (n = 3). (E) Representative contact angle images between water and the assembled membranes (n = 3). (F) Young’s modulus (MPa, n = 4). (G) Tensile strength (MPa, n = 4). (H) Elongation at break (%, n = 4) under dry (uncrosslinked) and wet (crosslinked) conditions.
