Morphological changes in the electrospun fibers of chitosan10. Chitosan10 was dissolved in trifluoroacetic acid (TFA) at the specified concentration; then the chitosan-TFA solutions were electrospun. Chitosan10 concentrations were 5 wt% (a; magnification, ×1000), 6 wt% (b, ×1000), 7 wt% (c, ×1000; d, ×10000), and 8 wt% (e, ×1000; f, ×10000). (With permission from John Wiley and Sons).
