iron oxide nanoparticles were synthesized by coprecipitation method using ammonia as precipitation agent. most researchers usually add ammonia into the iron salt solution but in this work the salt solution drop wise has been added to the ammonia and the new obtained results were compared with those of other researches. magnetic properties of nanoparticles were measured by vsm. the effect of rea...

Magnetic nanoparticles offer some attractive possibilities in biomedicine because it has the special physical properties. Magnetic hyperthermia using magnetic nanoparticles requires that the magnetic particles have not only high heating ability in low magnetic field but also to be non-toxic for biomedical use. Although the reports of bulk magnetic materials or Fe3O4 nanoparticles have known for...

Magnetite (Fe3O4) nanoparticles were synthesized by coprecipitation route. Coprecipitation is a simple, reproducible and accessible technique relying on the coprecipitation of Fe2+ and Fe3+ cations by NaOH as base at low temperature (~80 °C). In this work, the role of different solvents (H2O, ethylene glycol, diethylene glycol, triethylene glycol) on phase, structure, microstructure and magneti...

   In recent years, Hyperthermia has been used as an emerging technique for cancer treatment, especially for localized tumors. One of the promising cancer treatment approaches is magnetic nanoparticle (MNPs) Hyperthermia. In this theoretical work, the temperature distribution of a common tumor over the different sizes of Fe3O4 magnetic nanoparticles, namely 25, 50, 100, and 200 nm, was stud...

superparamagnetic single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 20 °c without any subsequent calcination. the composition, crystallite size, microstructure and magnetic properties of the prepared nanoparticles were investigated using x-ray diffraction (xrd), field emission scanning electron microscope (fesem), transmission electron microscope (tem), fou...

Nickel ferrite nanoparticles with superparamagnetic behavior at room temperature were synthesized using a coprecipitation method. These magnetic nanoparticles were either covered with a lipid bilayer, forming dry magnetic liposomes (DMLs), or entrapped in liposomes, originating aqueous magnetoliposomes (AMLs). A new and promising method for the synthesis of DMLs is described. The presence of th...
