摘要：
This paper presents a method for the chemical synthesis and characterization of Fe3O4 magnetic nanoparticles (MNPs). In the work, MNPs were fabricated by chemical co-precipitation. The stoichiometric ratio of Fe2+/Fe3+ was 2:3, and polyethylene glycol 2000 (PEG-2000) was chosen as the dispersant. Isolated single MNPs were obtained from the diluted solution of MNPs dried on a clean silicon wafer surface. The Xray diffractometer (XRD), scanning electron microscope (SEM) and magnetic force microscope (MFM) were used to characterize the Fe3O4 MNPs. The fabricated Fe3O4 MNPs were paramagnetic and able to be separated from the solution by a magnet. The experiment results have shown that this method can obtain the decentralized MNPs with the average diameter of 99.6 nm for different potential applications.
