3.1. Structural analysis
The microstructure of fabricated scaffolds was assessed using SEM images (Fig. 1a-e). The data revealed that all scaffolds exhibited homogeneous porous structures with interconnected pores. As reported in our previous study [24], the average pore sizes were measured as 162.5, 147.4, 142.5, 116, and 114.7 µm for SA, GOSA0.5, GOSA1, RGOSA0.5 and RGOSA1, respectively. These observations show the dependency of composite scaffold pore size on GO concentration.
