(A) SR for the pristine hydrogel and hybrid materials with the sodium ALN carrier incubated in PBS for 24 h. * indicates statistical significance when compared with ColChHA_mod C1. (B) Contact angle values (deg) measured on surfaces of tested materials. (C) Changes in the pristine hydrogel and hybrid material weight during 144 h of enzymatic degradation. Statistical analysis was carried out by comparing all types of materials at the same time of degradation. * indicates statistical significance when compared with ColChHA_mod after 24 h of experiment, # indicates statistical significance when compared with ColChHA_mod after 72 h of experiment, and ^ indicates statistical significance when compared with ColChHA_mod after 144 h of experiment. (D) Values of the storage modulus (G′) measured in 10, 35, and 70 min after starting the experiment are presented on a logarithmic scale. Statistical significance was calculated using Student’s t-test. A comparison between two means was analyzed with a statistical significance level set at p < 0.05; * indicates statistical significance when compared with ColChHA_mod after 70 min and # indicates statistical significance when compared with ColChHA_mod after 70 min.
