The synthesis of highly crystalline and monodisperse gamma-Fe(2)O(3) nanocrystallites is reported. High-temperature (300 degrees C) aging of iron-oleic acid metal complex, which was prepared by the thermal decomposition of iron pentacarbonyl in the presence of oleic acid at 100 degrees C, was found to generate monodisperse iron nanoparticles. The resulting iron nanoparticles were transformed to...

Fe-doped La0.77Sr0.23Mn1 - y Fe y O3 nanoparticles have been synthesized by sol-gel method, and ceramic samples based on them were sintered at 1613 K. Crystallographic and magnetic properties of obtained nanoparticles and ceramic samples have been studied. It has been established that cell volume for nanoparticles increases with growing of iron content, while this dependence displays an opposit...

UNLABELLED In this work, the magnetic properties of silicon nanotubes (SiNTs) filled with Fe3O4 nanoparticles (NPs) are investigated. SiNTs with different wall thicknesses of 10 and 70 nm and an inner diameter of approximately 50 nm are prepared and filled with superparamagnetic iron oxide nanoparticles of 4 and 10 nm in diameter. The infiltration process of the NPs into the tubes and dependenc...

The methods of the published manuscript [1] state that an incorrect concentration of Feridex was used (25 ug/ml). Instead, the methods should state that a concentration of 50 ug/ml Feridex was used. Optimized labeling of bone marrow mesenchymal cells with superparamagnetic iron oxide nanoparticles and in vivo visualization by magnetic resonance imaging.

Introduction MRI is a high spatial resolution non-invasive technique but it has low specificity for targeting explicit pathologies. In an effort to improve specificity, MRI contrast agents with strong paramagnetic properties such as Gadolinium have been developed. However recent reports of suspected deaths associated with gadolinium administration have severely limited their use [1-2]. Iron oxi...

Background and Aims: Iron oxide nanoparticles are among the most effective tools which can replace current medical techniques for diagnosis and treatment of various diseases. Hepatitis C infection is one of the main health problems in the world, affecting around 3% of the world's population. This infection can develop into liver cirrhosis and liver cancer over the time in 80% of patients. In t...

Background: Despite the wide range of applications, there is a serious lack of information on the impact of the nanoparticles on human health and the environment. The present study was done to determine the range of dangerous concentrations of iron oxide nanoparticle and their effects on mouse embryonic stem cells. Methods: Iron oxide nanoparticles with less than 20 nanometers diameter were en...

Various types, shapes and sizes of iron oxide nanoparticles were obtained depending on the nature of the precursor, preparation method and reaction conditions. The mixed valence trinuclear iron acetate, [Fe2IIIFeIIO(CH3COO)6(H2O)3]·2H2O (FeAc1), μ3-oxo trinuclear iron(III) acetate, [Fe3O(CH3COO)6(H2O)3]NO3∙4H2O (FeAc2), iron furoate, [Fe3O(C4H3OCOO)6(CH3OH)3]NO3∙2CH3OH (FeF), iron chromium furo...

BACKGROUND Accumulating evidence indicates that iron oxide nanoparticles modulate immune responses, and induce oxidative stress in macrophages. It was recently reported that iron oxide nanoparticles attenuated antigen-specific immunity in vivo, though the underlying mechanism remains elusive. The present study investigates the direct effect of iron oxide nanoparticles on antigen-specific cytoki...

The production and use of iron oxide nanoparticles are growing exponentially due to its wide applications in different fields of science and technology. The objective of this study is to synthesize iron oxide nanoparticles, and modification of its surface to make it less toxic. The iron oxide nanoparticles were synthesized by chemical co-precipitation method, and surface modification was done u...
