Characterization of poly-(ε-caprolactone) (PCL) nanofibrous scaffolds. a A 3D PCL nanofibrous scaffold placed in a 24-well tissue culture plate. b Scanning electron microscopy (SEM) images of the electrospun 3D PCL nanofibrous scaffold at 5 000× original magnification; scale bar, 50.0 μm. c 10,000× original magnification; scale bar, 5.0 μm. d Coated with gelatin, 5000× original magnification; scale bar, 50.0 μm. e PCL fiber diameter analysis. AD: average diameter; SD: standard error. n = 217 from 6 samples. f Water droplet on a 3D PCL nanofibrous scaffold and contact angle (θ) measurement
