Physicochemical properties of nanofiber. a) FT-IR spectrum of PCL nanofiber, PCL/DA nanofiber, PCL/PDA film, and PCL/PDA nanofiber. b) Specific modulus of nanofiber scaffolds. n=4 for PCL/DA and n=5 for PCL/PDA. c–i) Adhesion of fibronectin on (c–e) PCL/PDA and (f–h) PCL/DA nanofiber. Scales are 100 μm. (i) FN coverages on the nanofiber were calculated and plotted. **p<0.05, n=3, ROI = at least 25 for each condition.
