Levofloxacin-loaded nanofibrous scaffolds from chitosan (CS) and poly(ε-caprolactone) (PCL) were prepared using coaxial electrospinning for the controlled release of antibiotics. Levofloxacin was encapsulated in the CS phase as a core and PCL was employed to control the release of levofloxacin as a shell. The levofloxacin-loaded nanofibrous scaffolds prepared at different PCL concentrations (8, 12, 16, and 20 wt%) were characterized by SEM and TEM to confirm their surface morphology and core-shell structure. The nanofibrous scaffold prepared at a higher PCL concentration exhibited higher mechanical properties. In addition, the CS-PCL nanofibrous scaffold exhibited more sustained release of levofloxacin than PCL nanofibrous scaffolds prepared using both single and coaxial nozzles. This levofloxacin-loaded nanofibrous scaffold can potentially be employed for the sustained release of antibiotics after surgical operations.
