One-pot synthesis of stable colloidal solutions of MFe2O4 nanoparticles using oleylamine as solvent and stabilizer

Perspective of Fe3O4Nanoparticles Role in Biomedical Applications

“…Typically, the thermal decomposition method occurs from two approaches including the addition of hot solvents to reaction medium that can lead to fast nucleation process and the heating up of the reaction mixture up to decomposition temperatures. In the last approach, due to the relatively slow nucleation, the homogeneity of particles size and morphology is less than the first one [183]. The main disadvantages of this method include high required temperature (up to 300°C) for reflux process, complexity of long time consuming reaction, and depending on nonpolar organic solvents [184].…”

“…Pérez-Mirabet and colleagues performed pot synthetic methods by use of oleylamine as a multipurposes agent, for the sake of stabilization of particles in solution (stabilization agent) and control of particles size (capping agent). By this method, they could achieve monodisperse particles with average size of 12 nm that showed appropriate amount of M s equal to 76 emu/g [183]. Moreover, some researchers work on the solvent-free or/and biosolvents thermal decomposition methods that have more biocompatibility and less toxicity of precursors [185, 186].…”

New approach towards the polyol route to fabricate MFe2O4 magnetic nanoparticles: The use of MCl2 and Fe(acac)3 as chemical precursors

“…), the interest to tune their properties as wanted has been increasing in the last years. One developed route to modify the final physicochemical properties is the selection of the proper divalent cation, resulting in the correspondent mixed ferrite with their exclusive properties [8][9][10][11], methodology in which this work was focused to study the nanoparticle composition, growth and dispersion.…”

Synthesis and magneto-electrical properties of MFe2O4 (Co, Zn) nanoparticles by oleylamine route

“…The second weight loss of 42% the between 240 and 480°C is associated with the decoordination of the oleylamine from the NPs surface. As a third step, 13% mass loss can be observed between 480 and 750°C indicating a phase change and formation of more oxidative particles[23]. TG of CoFe 2 O 4 @OAm and ZnFe 2 O 4 @OAm NPs.…”
