A new method for the green synthesis of Fe3O4 nanoparticles using Alliaceae plant extract and investigating their properties

Abstract

Abstract Introduction: In recent years, iron oxide-based magnetic nanoparticles have been widely used for a variety of environmental and medical applications, including the purification and separation of pharmaceutical, dye, and heavy metal contaminants, as well as drug delivery and labeling systems. Due to the fact that magnetite (Fe3O4) has superior magnetic and electrical properties, iron oxide has attracted the most interest among many nanostructured materials. Methods: In this research, magnetite nanoparticles (Fe3O4) were successfully synthesized using a green process. This method is simple, fast, cost-effective, and biocompatible. Allium hooshidaryae (Alliaceae) plant extract was used as a stabilizing and reducing agent in this process. Green synthesized nanoparticles were characterized by several structural and physical techniques, like Vibrating Sample Magnetometer (VSM), X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Energy Dispersive X-ray Spectroscopy (EDS), Transmission Electron Microscope (TEM) ) and scanning electron microscope (SEM). Findings: XRD results showed that the synthesized nanoparticles are FCC structure with high purity. FTIR results proved the binding of functional group present in this plant and Fe3O4 nanoparticles. Also, in FTIR analysis, the presence of two absorption peaks of 559.96 cm-1 and 432.57 cm-1 confirmed the successful green synthesis of Fe3O4 nanoparticles. SEM and TEM images showed that the green synthesized Fe3O4 nanoparticles are mostly spherical and have an average size of 35.73 nm. As a result, the synthesized nanoparticles have the potential to have useful benefits in future nanomedicine
