Characterization of the hydrophilicity and in vitro biodegradation behavior of the scaffolds. (a) The contact angle images and measurements of the scaffolds with different concentrations of rGO. Results are presented as mean ± SD (n = 5). (b,c) The in vitro degradation behavior of the 3D printed scaffolds after incubation in SBF over the course of 14 days and under physiological conditions. The (b) swelling rate and (c) weight loss of the scaffolds expressed in % and presented as mean ± SD (n = 3) (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001).
