Size-Controlled Synthesis of Magnetite Nanoparticles
Journal of the American Chemical Society, 2002Monodisperse magnetite nanoparticles have been synthesized by high-temperature solution-phase reaction of Fe(acac)3 in phenyl ether with alcohol, oleic acid, and oleylamine. Seed-mediated growth is used to control Fe3O4 nanoparticle size, and variously sized nanoparticles from 3 to 20 nm have been produced.

Lanthanide(III)-Doped Magnetite Nanoparticles
Journal of the American Chemical Society, 2009Nearly monodisperse lanthanide-doped magnetite nanoparticles were obtained by thermally decomposing a mixture of Fe(acac)(3) and Ln(acac)(3) (acac = acetylacetonate; Ln = Sm, Eu, Gd) in the presence of passivating surfactants. Magnetic studies revealed room-temperature ferromagnetic behaviors of these doped nanoparticles, distinctly different from ...

Characterization of magnetite nanoparticles
2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2014This paper deals with the chemical preparation and magnetic characterization of nanoparticles of magnetite. A new hydrothermal synthesis of magnetite is adopted to prepare samples with different particle sizes and magnetic measurements are performed in two different laboratories adopting two different measurement methods.

Interaction of fibrinogen with magnetite nanoparticles
Biophysics, 2010The interaction between fibrinogen and magnetite nanoparticles in solution has been studied by the methods of spin labeling, ferromagnetic resonance, dynamic and Rayleigh light scattering. It was shown that protein molecules adsorb on the surface of nanoparticles to form multilayer protein covers.

Fortification of water kefir with magnetite nanoparticles
Food Research International, 2021The aim of this work was to evaluate the suitability of incorporating Fe3O4 (magnetite, M) NPs into water kefir (wKef) beverages. Magnetite NPs were synthesized and coated with pectins (cM), and incorporated into wKef beverages obtained by fermentation of a muscovado sugar solution with wKef grains.

Organophosphorous functionalization of magnetite nanoparticles
Colloids and Surfaces B: Biointerfaces, 2013In this work magnetite nanoparticles covered by gold and silver shell were obtained. Analyzed particles were modified by two kinds of organophosphorous compounds: 3-phosphonopropionic acid and 16-phosphonohexadecanoic acid. Enzyme immobilization on particles modified in such a way was tested.

Extracellular Synthesis of Magnetite and Metal-Substituted Magnetite Nanoparticles
Journal of Nanoscience and Nanotechnology, 2006We have developed a novel microbial process that exploits the ability of Fe(III)-reducing microorganisms to produce copious amounts of extracellular magentites and metal-substituted magnetite nanoparticles. The Fe(III)-reducing bacteria (Theroanaerobacter ethanolicus and Shewanella sp.) have the ability to reduce Fe(III) and various metals in aqueous ...

This study is focused on a simple and fast synthesis of nonstoichiometric magnetite nanoparticles with the chemical formula Fe3−XO4 and magnesium ferrite nanoparticles (Mg1−XFe2+XO4). The nanoparticles were prepared with Fe2+ ions (FeSO4 · H2O) alkalised by KOH under oxidative conditions and in a microwave field.
