Figure 1From: Preparation and characterization of biomimetic silk fibroin/chitosan composite nanofibers by electrospinning for osteoblasts cultureSEM micrographs (A to E) and histograms of fiber diameters (F to J). Electrospun SF/CS nanofibers with different CS contents: (A), (F) 100% CS; (B), (G) 75% CS; (C), (H) 50% CS; (D), (I) 25% CS; and (E), (J) 0% CS. Bar = 10 μm.Back to article page
