In the present study, we have achieved to provide an efficient method for production of iron oxide magnetic nanoparticles with arginine capping using in situ and one-pot co-precipitation method. As a novel drug delivery system, methotrexate (MTX) was conjugated to the obtained nanoparticles. These magnetic nanoparticles conjugate can potentially use in controlled drug delivery as carrier, and in magnetic resonance imaging as a contrast agent. Also, these nanoparticles can serve as a target in cancer therapy and diagnosis. These magnetic nanoparticles were covalently bound with MTX and can target the majority of cancer cells that their surfaces overexpressed by folate receptors. These conjugated nanoparticles were obtained through amide bond between the amine groups on their surface and the carboxylic acid end groups on MTX due to being functionalized with arginine. MTX was cleaved from nanoparticles according to drug release experiments in the presence of protease-like lysosomal conditions. Fe-Arg-MTX was characterized by transmission electron microscopes, dynamic light scattering, thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction and Fourier transform infrared spectroscopy. Furthermore, vibrating sample magnetometry analysis showed excellent magnetic properties of them. The average particle size of Fe-Arg-MTX was approximately 27 nm. The result revealed that the bare nanoparticles have no cytotoxicity against MCF-7, 4T1 and HFF-2 cell lines. Hemolysis assay showed that these nanoparticles are biocompatible. Regarding the research success, an efficient technique can be presented for drug delivery and controlled release and for studying cancer-fighting in alive creature's bodies.
