SEM images and distributions of the diameters of PLGA solution/collagen solutions.
Notes: PLGA solution/collagen solutions of (A and F) 40/60 v/v, (B and G) 50/50 v/v, (C and H) 67/33 v/v, (D and I) 80/20 v/v, and (E and J) 100/0 v/v showed a distribution of diameters, and SEM images demonstrate nanofibers at a magnification of ×4,500. All electrospun nanofibers showed high levels of porosity.
Abbreviations: PLGA, poly(D,L-lactide-co-glycolide); SEM, scanning electron microscope.
