Abstract

Herein iron oxide nanoparticles were successfully prepared from FeCl3·6H2O (1.1 g) and FeCl2·4H2O (0.4 g) by addition of ammonium hydroxide via coprecipitation method (CPC). The conditions for the preparation of IONPs were optimized. IONPs were characterized by transmission electron microscope (TEM) and vibrating sample magnetometer (VSM). Magnetic electrospun nanofibers based on Fe3O4 nanoparticles/PVA/chitosan/collagen were fabricated using an electrospinning technique. In the absence and presence of ciprofloxacin, nanofibers were made from Fe3O4 nanoparticles that made up around 10% of the polymers. The viscosity and conductivity of several composite polymer formulations were measured as critical metrics. The electrospun nanofibers were characterized by Fourier transformation infrared spectroscopy (ATR‐ FTIR) and scanning electron microscope (SEM). The diameter of the nanofibers, antibacterial capabilities, and magnetism of the nanofibers were all measured. Electrospun magnetic nanofibers with higher antibacterial activity and supermagnetism were produced. In addition, the use of ciprofloxacin antibiotics improved these qualities.
