Synthesis, Characterization and Antibacterial Properties of Novel One-Dimensional Composite Nanofibers

The novel beta-cyclodextrin/poly(N-vinylpyrrolidone) (beta-CD/PVP) composite nanofibers containning silver nanoparticles were successfully prepared via electrospinning technique. Silver nanoparticles were synthesized using silver nitrate as the precursor, ethanol as solvent and poly(N-vinylpyrrolidone) (PVP) introduced as a capping agent and the Ag nanoparticles were obtained in solution. The colloidal silver prepared in a PVP solution was directly mixed into beta-CD/DMF solution matrix to form the composite solution and then the prepared solution was electrospun to fabricate AgNPs/beta-CD-PVP composite nanofibers. Scanning electron microscopy was used to study the morphology of the composite fibers, transmission electron microscopy images showed that the silver nanoparticles were well separately dispersed in beta-CD/PVP matrix. The antimicrobial properties were also investigated.
