Resumen:
The hyperthermia technique consists in inducing cell death by generating an increase of the local temperature of a tumor. This heating is mediated by superparamagnetic iron oxide nanoparticles (SPIONs) that are absorbed by cancer cells and when they interact with an AC magnetic field, transform the energy received from the field in thermal energy.We have synthetized Fe3O4 SPIONs and obtained well-crystalline nanoparticles of different sizes. SPIONs exhibited high saturation magnetization and superparamagnetic behavior at room temperature. Once hydrophobic SPIONs were obtained, they were suspended in aqueous media by the method of ligand exchange. Specific absorption rate (SAR) measurements were performed on a commercial device.
