Magnetite Nanoparticles Encapsulated with PBS-PEG for AMF Hyperthermia

Novel studies on typical synthesized magnetite nanoparticles were encapsulated into a poly (butylene succinate)/poly (ethylene glycol) copolymer (PBS-PEG). PBS was chosen because of its biocompatibility characteristics necessary for biomedical applications. PEG, as part of the macromolecular structure, increases the hybrid system's solubility in an aqueous environment, increasing the circulation time of the material in the bloodstream. The immune system has difficulty recognizing particles with good solubility in an aqueous medium and with a diameter until 200 nm, preventing the body from eliminating the nanoparticles before the magnetic hyperthermia is performed. All the prepared materials were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic light scattering (DLS), and zeta potential. The detailed investigated result executes the formulation developed in this work, showing it has potential and that further studies and analyses can be carried out so that the formulation can be improved, thus obtaining even better results.
