Preparation and Characterization of Amoxicillin-Loaded Polyvinyl Alcohol/Sodium Alginate Nanofibrous Mat: Drug Release Properties, Antibacterial Activity, and Cytotoxicity

This study aimed to prepare a polyvinyl alcohol/sodium alginate (PVSA) nanofibrous mat as an amoxicillin (AMOX) delivery system. AMOX was loaded to the PVSA nanofibers during electrospinning, and the AMOX-loaded PVSA (PVSA/AMOX) nanofibrous mat was cross-linked by glutaraldehyde (GA). The PVSA/AMOX nanofibrous mat was characterized by Fourier Transform infrared spectroscopy, scanning electron microscopy, Brunauer–Emmett–Teller, and mercury porosimetry analyses. The thickness, air permeability, and water vapor transmission rate of the PVSA/AMOX nanofibrous mat were 0.43 ± 0.08 mm, 17.2 ± 4.91 L/m2/s, and 1485 ± 13.6 g/m2/d, respectively, which were suitable for wound dressing applications. The tensile strength was 6.73 ± 0.48 MPa and elongation at a maximum load was 81.9 ± 17.0
