Abstract

The present disclosure provides a method for producing a cell-culturing polyvinyl alcohol-based nanofiber structure, the method comprising: electrospinning an electrospun solution to form a nanofiber mat, wherein the electrospun solution contains polyvinyl alcohol (PVA), polyacrylic acid (PA) and glutaraldehyde (GA); crosslinking the nanofiber mat via a hydrochloric acid (HCl) vapor treatment; and treating the crosslinked nanofiber mat with dimethylformamide (DMF) solvent to crystallize the nanofiber mat.
