Characterization of a lysozyme-chitosan conjugate hydrogel. (a) Macroscopic observation of hydrogel degradation with lysozyme modification for 14 days. Scale bar is 5mm. (b) Degradation profile measured by the dry weight change of hydrogels for two weeks. (c) Swelling ratio of hydrogels calculated by the proportion of wet and dry weight of hydrogels for two weeks. (d) Compressive modulus of hydrogels with RGD and lysozyme modification for two weeks. *p < 0.05, **p < 0.01, ***p < 0.001 compared to ML0. #p < 0.01 compared to RL0. p < 0.01 compared to ML0.1.
