摘要：

Antimicrobial activity of ZnO nanomaterials has received global interest due to high surface to volume ratio. In the present study, ultra-thin ZnO nanofibers in poly vinyl alcohol (PVA) has been electrospun. Calcination of mentioned precursor fibers was done at 400 and 500 degrees C for 3, respectively. Rietveld refinement of XRD pattern confirms the hexagonal wurtzite structure (with space group = P63 mc) of ZnO nanofibers. SEM images reveal that the ZnO nanofibers have an average diameter of 315-292 nm. The earliest findings suggest that electrospun ZnO nanofibers are effective at exterminating Escherichia coli and Staphylococcus aureus cells by the destruction of the cell wall and affecting the genetic material of the bacterial cells.
