Figure 3

Three-dimensional spatial structure and characterization of the scaffolds. (a–c) SEM images of scaffolds formed at −20 °C, −80 °C and −178 °C (scale bar = 500 μm). (d–f) Enlarged view of (a–c) (scale bar = 100 μm). (g,h) Storage modulus (G′) and loss modulus (G″) of SF/MAHA scaffolds under different SF concentrations (* p < 0.05); (i) Enzymatic degradation of SF/MAHA scaffolds under different SF concentrations. MAHA, methacrylated hyaluronic acid. SEM, scanning electron microscopy. SF, silk fibroin.
