چکیده	In recent years, the use of nanoparticles in the field of medicine has attracted many attentions. The surface coating of nanoparticles by biocompatible polymers improves their bioavailability. Due to the compatibility of bio-polymers with the environment and human body, these materials are used as carrier agents. In this research, magnetic nanoparticles were synthesized by microwave and hydrothermal methods. The iron oxide nanoparticles (Fe3O4) were coated with polyvinyl alcohol (PVA) to prepare nanocomposite and load the drug (vitamin C) from the mechanical agitator. The nanoparticles crystal structure was studied using X-ray diffraction (XRD). The nanoparticles size was determined by scanning electron microscopy (SEM). Vibrating sample magnetometer (VSM) was used for magnetic analysis, and the purity of the material was determined by applying Fourier transform infrared spectrometer (FT-IR). Evaluation of drug release was investigated by ultra violet-visible (UV-Vis) spectroscopy.
