Blocking Properties of Superparamagnetic Magnetite Nanoparticles and Gold/Superparamagnetic Magnetite Composite Nanoparticles

Advanced Materials Research, 2015
The UV and IR block properties of superparamagnetic magnetite nanoparticles (SPMN) and SPMN/gold composite nanoparticles are investigated. The composite nanoparticles were prepared via sonochemical assisted reduction of gold precursor and deposition of gold nanoparticles (GNP) on amine functionalized SPMN.

Tissue Engineering Using Magnetite Nanoparticles

2011
The major advantage of magnetic manipulation is "remote control." Magnetic labeling of cells with magnetic nanoparticles enables the manipulation of cells and also the control of cell functions by applying an external magnetic field. "Functional" magnetite nanoparticles were developed for cell manipulation using magnetic force, and the magnetite ...

Stability of core–shell magnetite nanoparticles

Colloids and Surfaces B: Biointerfaces, 2014
In the paper, we present three different types of magnetite nanoparticles which were prepared from co-percipitation of iron (II) and (III) chlorides in aqueous solution with and without SiO2 and from thermal decomposition of iron (III) acetylacetonate in nonaqeous solutions.

Synthesis and characterization of magnetite nanoparticles from mineral magnetite

Journal of Magnetism and Magnetic Materials, 2013
Abstract We have synthesized magnetite nanoparticles with sizes that range from 20 to 30 nm from mineral magnetite roughly 45 μm in size. The procedure consists in the dissolution of the mineral in an acidic medium and subsequent precipitation in a basic medium in the presence of oleic acid.

On the adsorption of magnetite nanoparticles on lysozyme amyloid fibrils

Colloids and Surfaces B: Biointerfaces, 2016
An adsorption of magnetic nanoparticles (MNP) from electrostatically stabilized aqueous ferrofluids on amyloid fibrils of hen egg white lysozyme (HEWL) in 2mg/mL acidic dispersions have been detected for the MNP concentration range of 0.01-0.1vol.%.

Mössbauer studies of magnetite nanoparticles

Journal of Surface Investigation. X-ray, Synchrotron and Neutron Techniques, 2014
Magnetite Fe3O4 samples with different levels of dispersion (“bulk” and nanoscale particles with an average diameter of 24, 14 and 7 nm) are studied using Mossbauer spectroscopy. It is shown that this method of analysis makes it possible to obtain important information about the features of magnetic states of iron-containing nanoparticles and, more ...

Sorption of uranium on magnetite nanoparticles

Journal of Radioanalytical and Nuclear Chemistry, 2010
Magnetite (Fe3O4) nanoparticle was synthesized using a solid state mechanochemical method and used for studying the sorption of uranium(VI) from aqueous solution onto the nanomaterial. The synthesized product is characterized using SEM, XRD and XPS. The particles were found to be largely agglomerated.

The synthesis of octahedral nanoparticles of magnetite

Materials Letters, 2006
Abstract This work presents an efficient method of largely synthesizing octahedral magnetite nanoparticles. Without any surfactant, octahedral magnetite nanoparticles were successfully achieved by means of an oxidation–precipitation method with ferrous sulfate as starting material, which was pro rata oxidized to ferric salts by NaNO 3 after ...

 Magnetotransport of magnetite nanoparticle arrays

Physical Review B, 2006
We combine a material self-assembly with conventional lithographic processes in order to fabricate magnetoelectronic devices composed of ordered three-dimensional arrays of magnetite $({\mathrm{Fe}}_{3}{\mathrm{O}}_{4})$ nanoparticles. The device magnetoresistance reaches 35% at 60 K, corresponding to an electron spin polarization of 73 ...
