Use of water-dispersible Fe2O3 nanoparticles with narrow size distributions in isolating avidin

Perspective of Fe3O4Nanoparticles Role in Biomedical Applications

“…Commonly, water soluble surfactants are utilized to transformation of hydrophobic nanoparticles to hydrophilic mode in aqueous solutions. The mechanism of this method is based on stabilization of particles by adding bipolar surfactants, that is, amino acid, citric acid, vitamin, and polyethylene glycol [207–211]. The functionalization by water soluble surfactants can be performed on the basis of two approaches.…”

“…This one-pot method is most appropriate for creation of matrix structures. In fact, by adding excess amounts of surfactants, the coating aggregate particles are formed as matrix structures [207–211]. Second approach is the usage of ligand exchange mechanism by adding oil soluble ligand to synthesized particles mixture.…”

Effect of sodium oleate as a buffer on the synthesis of superparamagnetic magnetite colloids

“…Because of their unique properties in the magnetic field, extensive applications have been developed for more than three decades, such as magnetic sealing [1,2], heat transfer [3], damping [4], optics [5,6], as well as biomedical engineering [7,8]. Most applications require that MNPs are monodisperse and nonagglomerated in solvents for homogeneous physical and chemical properties, which has motivated much research in the preparation and processing of stable ferrofluids.…”

Advances in magnetic nanoparticles for biotechnology applications

“…It is also worth mentioning the work of Gao's group on the use of hydrophobic monodisperse g-Fe 2 O 3 for biomedical applications [23]. These authors use 13 nm monodisperse g-Fe 2 O 3 nanomagnets prepared by the Hyeon method (thermal decomposition of Fe(CO) 5 in the presence of surfactants and a mild oxidant) [24].…”
