Figure 1.

Scanning electron microscopic morphology of electrospun PGA/gelatin nanofibers (2000× and 20,000× magnification). (A) Pure PGA, (B) PGA/10 wt% gelatin, (C) PGA/30 wt% gelatin, and (D) PGA/50 wt% gelatin. (E) Mean diameter (± standard deviation) variations of electrospun PGA/gelatin fibers, (F) mean area (± standard deviation) between fibers, and (G) distribution of fiber orientation angles (n = 50).

Notes: ***P < 0.001, significantly different from the previous group.

Abbreviation: PGA, polyglycolic acid.
