The contribution of magnetic nanoparticles to the field of cancer treatment has recently created an immense impact with various modalities. In the present work, we report the fabrication of magnetic iron oxide nanoparticles (IONPs) coated with biocompatible natural polymer gelatin, followed by cross-linking of the adsorbed model drug, doxorubicin (DOX) on the surface of the nanoparticles using a natural cross-linker genipin. The particles were characterized by evaluating the zeta potential, VSM, hyperthermia and X-ray diffraction. To investigate the morphology of the IONPs, field emission scanning electron microscopy (FE-SEM) was used. The functional and elemental group was evaluated by FTIR. The drug loading efficiency and drug release kinetics were studied, whereas the toxicity of gelatin-coated IONPs was evaluated by MTT assay using MG-63 osteosarcoma cells. The nanoparticles show good superparamagnetic properties exhibiting a potential hyperthermia effect with enhanced drug release on an increase in temperature. The cell viability assay displayed that gelatin-coated IONPs are non-toxic thus making it a potential candidate suitable for application in anti-cancer treatment.
