To date, high mortality in women due to malignancy breast cancer related to the metastasis to the bone is a significant challenge. As, magnetic nanoparticles (MNPs) conjugated with the biocompatible polymers was employed for the delivery of some hydrophobic anticancer agents, the main aim of the current research was to assess whether cisplatin‐loaded MNPs enhanced the anticancer effect of free cisplatin in breast cancer cells. MNPs decorated with PEG were synthesized by an improved coprecipitation technique, and then cisplatin was loaded onto the MNPs via a simple mixing method. Afterward, its morphology, size, chemical structure, magnetic property, hydrodynamic diameter, zeta potential, and crystal structure were characterized by scanning and transmittance electron microscopy, Fourier transforms infrared spectroscopy, vibrating sample magnetometer, dynamic light scattering, and X‐ray powder diffraction and flame atomic absorption spectroscopy respectively. Additionally, the effects of cisplatin and MNPs‐PEG‐cisplatin on viability, migration and adhesion capacity of T47D cells were investigated by evaluating α2‐integrin and β1‐integrin; mRNAs were assessed by real‐time RT‐PCR. Consequently, the in vitro assay results showed a considerable dose‐dependent inhibitory effect of cisplatin and MNPs‐PEG‐cisplatin on proliferation, migration, and adhesion of T47D cells. Finally, current research was shown that MNPs‐PEG‐cisplatin strongly increased anticancer effects compared with free cisplatin in the T47D cell line.
