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

Abstract

The novel b-cyclodextrin/poly(N-vinylpyrrolidone) (b-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 b-CD/DMF solution matrix to form the composite solution and then the prepared solution was electrospun to fabricate AgNPs/b-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 b-CD/PVP matrix. The antimicrobial properties were also investigated.
