“…[ 33 ] Thermal decomposition of Fe(acac) 3 in a mixture of oleic acid and oleylamine led to the formation of wüstite (FeO) NPs. [ 34 ] The size of the FeO NPs was controlled in the range 14-100 nm and the shapes were either polyhedra or truncated octahedra, depending on the molar ratio of oleic acid to oleylamine. The FeO NPs can be converted to magnetite, maghemite (γ-Fe 2 O 3 ), hematite (α-Fe 2 O 3 ) NPs and Fe/Fe 3 O 4 , offering a general approach to the synthesis of NPs of various iron oxides.…”

Synthesis of multifunctional magnetic nanoparticles (MFMNPs) is one of the most active research areas in advanced materials. MFMNPs that have magnetic properties and other functionalities have been demonstrated to show great promise as multimodality imaging probes. Their multifunctional surfaces also allow rational conjugations of biological and drug molecules,making it possible to achieve target-specific diagnostics and therapeutics.This review fi rst outlines the synthesis of MNPs of metal oxides and alloy sand then focuses on recent developments in the fabrication of MFMNPs of core/shell, dumbbell, and composite hybrid type. It also summarizes the general strategies applied for NP surface functionalization. The review further highlights some exciting examples of these MFMNPs for multimodality imaging and for target-specific drug/gene delivery applications.

“…Indeed, only a few papers report on the preparation of Fe 1Ày O nanoparticles. [5][6][7] Iron monoxide nanoparticles are usually prepared by decomposition of precursors at high temperatures, in organic solvents, and in the presence of capping agents. The high temperature synthesis allows the thermolysis of the precursors and yields nanoparticles with a variety of sizes and shapes.…”

Fe_1−yO Nanoparticles: Organometallic Synthesis and Magnetic Properties

Non-stoichiometric wüstite particles (Fe(1-y)O) are synthesized using the controlled room-temperature hydrolysis of the organometallic precursor {Fe[N(SiMe3)2]2}. Particles stabilized by hexadecylamine with a diameter of approximately 5 nm are obtained. For such small nanoparticles, a distorted crystallographic structure is evidenced by wide-angle X-ray scattering at room temperature and reported for the first time. The study of the magnetic properties indicates that these particles are composed of an antiferromagnetic core surrounded by a ferromagnetic shell. According to the Néel theory, we demonstrate that this shell consists of 1.5 % of Fe3+ ions ferromagnetically coupled with Fe2+ ions.
