Magnetic Nanoparticles for Hyperthermia Applications

Co-authors STIBOR Ivan

Magnetite and magnetic allyl acetic acid nanoparticles were prepared by using co-precipitation process of Fe2+ and Fe3+ in the presence of ammonium hydroxide solution. The prepared magnetic nanoparticles were characterized by fourier transform infrared (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM) and heating properties. When an alternating magnetic field is applied, magnetic materials are observed to heat as a result of losses and relaxation. The heat generated from samples was evaluated by exposing 20% and 30% magnetic particle suspension dispersed in distilled water an alternating current (AC) magnetic field for certain time. The comparative temperature rise of the magnetic nanoparticles against the exposure time (1-5 minute) in an AC field. Specific absorption rate (SAR) of the prepared magnetic nanoparticles finds out there promising in hyperthermia applications and to future work for binding drug on the surface of magnetic carrier.
