| الوصف: | Understanding the biophysical and magnetic interactions of nanoparticles (NPs) with cell mem-branes is critical for developing effective nanocarrier systems for drug delivery applications and targeted nanophysics applications. Recent discoveries in nanomedicine can be used to test an in vitro system that reproduce a similar tumor model. Iron-oxide nanoparticles can be used for diagnosis, as well as a good carrier of drugs and induced therapeutic for magnetic hyperthermia. In the present study, we engineered polyethylenimine-conjugated superparamagnetic iron-oxide nanoparticles (SPIONs) for the targeted delivery of chemotherapeutics on in vitro silico model. Doxorubicin is used to treat numerous types of tumors including breast cancer. The drug-coated mul-ti-functionalized nanoparticles, were assembled stepwise, with doxorubicin adsorbed to polyeth-ylenimine-iron oxide nanoparticles first, by electrostatic reaction and allowed for the complexation of doxorubicin.. The drug-coated particles were able to inhibit growth and proliferation of resistant cancer cells in vitro, indicating that the system has potential to act as an antimetastatic chemo-thermotherapeutic agent. Here, we demonstrated a sophisticated strategy to kill in a precise way only cancer cells by conjugating a magnetic nanoparticle to chemotherapeutic.
