Abstract
Magnetic nanoparticles have been synthesized in a very simple and economical way by the co-precipitation method, where the effect of molar concentrations of ferric chloride anhydrous (FeCl3) and iron (II) sulphate heptahydrate (FeSO4.7 H20) on magnetite synthesis has been investigated. Also, a detailed study was conducted to study the effect of magnetite and hematite on both normal and cancerous cell lines. After this, the magnetic nanoparticles obtained were analyzed by x-ray Diffraction (XRD), scanning electron microscope (SEM) - energy dispersive x-ray (EDX), Fourier transform infrared spectroscopy (FTIR), zeta potential, vibrating sample magnetometer (VSM), atomic force microscopy (AFM), MTT test, and cell apoptotic assay. The XRD peaks for magnetite were easily discernible in the final formulation. SEM images showed round particles in nano ranges, and FTIR peaks showed the presence of magnetite. Zeta potential showed surface charges. VSM showed the magnetic property of magnetite, and AFM confirmed SEM images. It can be concluded that magnetic nanoparticles were synthesized by the co-precipitation method using an optimized molar concentration of reagents. Also, the necessity of coating uncoated magnetic nanoparticles can be seen from the MTT assay. Cell apoptotic assays have shown that synthesized magnetite nanoparticles have shown potential apoptotic activity on cancer cell lines.
