Abstract

This study is focused on development of novel nanofibrous material with immobilized Ag ions. These nanofibers have a great potential for biomedical applications, especially for antimicrobial wound dressing. The hybrid silica/PVA nanofibers were prepared by electrospinning and thermally stabilized. Consequently, Ag ions were immobilized onto the surface of the nanofibers. It was proved that quantity of immobilized Ag ions depends on immobilizing process time. As SEM analysis shown, Ag ions were immobilized onto single fibers in continuous density. According to preliminary antibacterial in-vitro test, the hybrid nanofibers with Ag ions show significant antibacterial activity.

Keywords: Silica nanofibers, polyvinyl alcohol, Ag ions, antibacterial activity.
