Abstract
In recent years, the development of efficient green chemistry methods for synthesis of magnetic nanoparticles with properties of superparamagnetism in addition to their low toxicity and biocompatibility has attracted more attention. Magnetic nanoparticles have been used for different applications including biosensors, bioseparation, drug delivery, magnetic resonance imaging contrast agents, and hyperthermia treatment of cancer. In the present study, we report a rapid and greener synthesis of magnetite iron oxide nanoparticles (Fe3O4-NPs) in aqueous solution using Ferric chloride (FeCl3•6H2O), ferrous chloride (FeCl2•4H2O), Ammonium hydroxide (NH4OH) and Natural honey as Fe3O4-NPs precursors, reducing agent, stabilizer and capping agent respectively. The spherical particles with the size below 20 nm successfully synthesized. The obtained nanoparticles were characterized by X-ray diffraction (XRD) analysis, Field Emission Scanning Electron Microscope (FESEM), energy dispersive X-ray fluorescence (EDXF), high-resolution transmission electron microscopy (HR-TEM), Vibrating Sample Magnetometer (VSM), and Fourier transforms infrared spectroscopy (FT-IR). Moreover the effect of other parameters such as pH of the solution and different percent of the stabilizer on the Fe3O4 nanoparticles was studied.
