In this study, magnetic iron oxide nanoparticles (Fe3O4) with the size range of 20-30 nm were prepared by the modified controlled chemical co-precipitation method from the solution of ferrous/ferric mixed salt-solution in alkaline medium. In this process polyethylene glycol was used as a surfactant to prevent the solution from agglomeration. The prepared magnetic nanoparticles were characterize...

In this study, copper manganese oxide (CuMn2O4) nanoparticles were successfully synthesized by a simple sol-gel technique in the presence of lactose as the green capping agent. The lactose concentration effect on the crystalline size and magnetic properties of final products were systematically investigated. The structural, morphological, magnetic, and optical properties o...

In this work, we investigated synthesis, magnetic properties of silica coated metal ferrite, (CoFe2O4)/SiO2 and Manganese doped cobalt ferrite nanoparticles (MnxCo1-xFe2O4 with x= 0.02, 0.04 and 0.06)/SiO2 for possible biomedical application. All the ferrites nanoparticles were prepared by co-precipitation method using FeCl3.6H2O, CoCl2.6H2O and MnCl2.2H2O as precursors, and were silica coated ...

This paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. Among common magnetic nanoparticles, magnetite (Fe3O4) and maghemite (g-Fe203) are popular candidates because of their biocompatibility. Natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...

magnetic cofe2o4 nanoparticles were synthesized via a simple chemical reaction using precipitation method. the obtained materials consist of ferrite particles with average diameter of 25 nm. the effect of different surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. scanning electron microscopy was used to study the structure and particle size o...
