Abstract: CeO2 nanospheres with different diameters were successfully prepared and embedded in one-dim- ensional chitosan/polyvinyl alcohol (CS/PVA) composite nanofibers by electrospinning technique for further antibacterial evaluation. The obtained composites exhibited different antibacterial activities to Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli). We propose that CeO2-CS/PVA nanofibrous membranes with attractive antibacterial activities witness the practical use for tissue engineering such as wound dressing.

 

Key words: antibacterial, CeO2 nanospheres, chitosan/polyvinyl alcohol fibers, electrospinning
