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 enc...

Polycrystalline iron phosphide coated iron oxide and hollow iron phosphide nanoparticles were synthesized by sonichemistry. Structure analysis indicated that the diameters of these nanoparticles were less than 14 nm, and the core–shell and hollow nanoparticles are Fe3O4–FeP and FeP, respectively. Magnetic measurement demonstrated that both the core–shell Fe3O4–FeP and hollow FeP nanoparticles e...

BACKGROUND Different superparamagnetic iron oxide nanoparticles have been tested for their potential use in cancer treatment, as they enter into cells with high effectiveness, do not induce cytotoxicity, and are retained for relatively long periods of time inside the cells. We have analyzed the interaction, internalization and biocompatibility of dimercaptosuccinic acid-coated superparamagnetic...

PURPOSE Cell-surface receptor-targeted magnetic iron oxide nanoparticles provide molecular magnetic resonance imaging contrast agents for improving specificity of the detection of human cancer. EXPERIMENTAL DESIGN The present study reports the development of a novel targeted iron oxide nanoparticle using a recombinant peptide containing the amino-terminal fragment of urokinase-type plasminoge...

The impacts of nanoparticles-zerovalent iron (NP-ZVI) on anaerobic co-digestion (AcoD) were assessed. production biogas and methane (CH4), as well the removal efficiency volatile solids (VS) contaminants investigated in AcoD chicken manure (CM) olive mill wastewater (OMWW) with addition NP-ZVI at different concentrations (10–50 mg/g VS) sizes resulting from various mixing volume ratios (MVR) Na...

Effects of heavy metals on the dechlorination of carbon tetrachloride by iron nanoparticles were investigated in terms of reaction kinetics and product distribution using batch systems. Removal of heavy metals and the interaction between heavy metals and iron nanoparticles at the iron surface were also examined. It was found that Cu(II) enhanced the carbon tetrachloride dechlorination by iron n...

Nanostructures loaded on halloysite nanotubes (HNTs) have attracted global interest, because the nanotubular HNTs could extend the range of their potential applications. In this study, we fabricated a novel nanocomposite with hollow iron nanoparticles loaded on the surface of HNTs. The structure of the iron nanoparticles can be adjusted by ageing time. Owing to the increased remnant magnetizati...

A composite of nano-zerovalent iron (nZVI) supported on granular activated carbon (GAC) was synthesizedthrough adsorption-reduction method, and its performances used as catalyst of Fenton-like were investigated to degrade methylene blue (MB) in model wastewater.Theresults show thathomogeneous dispersion of nZVI was greatly improved after supported on GAC. In comparison, the composite (nZVI/GAC)...

The purpose of this study was to synthesize biocompatible poly(2-hydroxyethyl aspartamide)-C16-iron oxide (PHEA-C16-iron oxide) nanoparticles and to evaluate their efficacy as a contrast agent for magnetic resonance imaging of lymph nodes. The PHEA-C16-iron oxide nanoparticles were synthesized by coprecipitation method. The core size of the PHEA-C16-iron oxide nanoparticles was about 5 to 7 nm,...
