Fabrication of nanofibers is a field of research attracting a lot of interest from technologici scientists because of its great applications in many fields. In order to design the polymer drug delivery system, we had to select a polymer that is biocompatible, biodegradable, non-toxic and approved for medical use. One of the polymers that fulfill those requirements is poly (vinyl alcohol) (PVA). There have been various reports on the fabrication of PVA nanofibers with solvents as water, or water with different salt...
