Fig. 1. Physical characteristics of SA/Ge scaffolds (A) SEM images of SA/Ge scaffolds with different SA/Ge ratios: (a) SA/Ge = 1 : 2, (b) SA/Ge = 1 : 1, (c) SA/Ge = 2 : 1, (d) SA/Ge = 4 : 1. The bar corresponds to 500 μm. (B) Swelling degree, (C) maximum tensile strength at breaking points, and (D) representative shift–loading curves of SA/Ge scaffolds in different ratios. * and ** denote significant difference at p < 0.05 and p < 0.01 levels, respectively.
