Macro- and microstructures of chitosan nanofibers.

Notes: Chitosan nanofiber scaffolds were prepared using an electrospinning setup. The macro- (A) and microstructures (B) of chitosan nanofibers were observed and photographed using a camera and light microscopy, respectively. The surface morphology of chitosan nanofiber scaffolds was further scanned and photographed using scanning electron microscopy (C).
