Synthesis of iron oxide magnetic nanoparticles and chitosan biopolymer in aqueous solutions

Abstract

This study focuses on the synthesis of iron oxide magnetic nanoparticles and their coating with chitosan biopolymer in aqueous solutions. The structural properties of the synthesized nanoparticles were characterized using Fourier Transform Infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), magnetic properties analysis using Vibrating Sample Magnetometry (VSM), and thermal gravimetric analysis (TGA). The FT-IR spectra confirmed the presence of iron oxide and chitosan on the nanoparticle surface. The XRD analysis indicated the crystalline nature of the nanoparticles, and SEM images revealed the morphology and particle size. The VSM results demonstrated the superparamagnetic behavior of the nanoparticles, and TGA analysis showed the thermal stability and decomposition of the nanoparticles. Overall, this synthesis method successfully produced iron oxide magnetic nanoparticles coated with chitosan, which have potential applications in drug delivery systems.
