Background: Ultrasmallsuperparamagnetic iron oxide (USPIO) nanoparticles are used as blood pool contrast agent for magnetic resonance angiography and perfusion imaging. Our aim in this study was to investigate the effect of the two coating types of iron oxide nanoparticles on the relationship between nanoparticles concentration and signal intensity (SI) in T1-weighted MR images.   Methods : D...

Present review article describes main causes of chronic kidney disease a major health problem public health problem round the globe. Disease has multiple etiologies related to sequential pathophysiological stages. It has major concern with chronic changes in renal structure and that severely alter glomerular filtration rate in patients. This article explains CKD biomarkers in brief i.e., serum ...

The impact of emerging contaminants in the presence of active pharmaceutical pollutants plays an important role in the persistence and activity of environmental bacteria. This manuscript focuses on the impact of amoxicillin functionalized iron oxide nanoparticles on bacterial growth, in the presence of dissolved organic carbon (humic acid). The impact of these emerging contaminants individually...

BACKGROUND In this work the chemical structure of dextran-iron oxide thin films was reported. The films were obtained by MAPLE technique from composite targets containing 10 wt. % dextran with 1 and 5 wt.% iron oxide nanoparticles (IONPs). The IONPs were synthesized by co-precipitation method. A KrF* excimer laser source (λ = 248 nm, τFWHM≅25 ns, ν = 10 Hz) was used for the growth of the hybrid...

Pilot experiments were performed. Microwave induced plasma decomposition of iron pentacarbonyl has been used to prepare iron nanosized particles. Vapours of iron pantacarbonyl have been introduced into argon surfaguide discharge, optical emission spectra have been taken and rotational temperatures obtained. The rotational temperatures remain practically constant during the increasing of the Fe(...

The special application of iron-manganese oxide nanocatalysts has been investigated in decomposition of hydrogen peroxide. In this research, iron-manganese oxide nanocomposites were synthesized by co-precipitation, sol-gel and mechanochemical methods using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared on the variou...

Magnetism has wide applications in various fields, such as diagnostics, drug targeting, molecular biology, cell isolation, cell purification, hyperthermia, and radioimmunoassay. In this study, we synthesized niosomes doped with iron oxide nanoparticles and a fluorophore for potential applications in magnetically targeted drug delivery. Release kinetics of the fluorophore and cytotoxicity were a...

We present a simple method for the co-encapsulation of gold nanostars and iron-oxide nanoparticles into hybrid colloidal composites that are highly responsive to both light and external magnetic fields. Self-assembly was driven by hydrophobic interactions between polystyrene capped gold nanostars and iron oxide nanocrystals stabilized with oleic acid, upon addition of water. A block copolymer w...

BACKGROUND Intrinsic iron in biological tissues frequently precludes unambiguous the identification of iron oxide nanoparticles when iron-based detection methods are used. Here we report the full methodology for synthesizing very small iron oxide nanoparticles (VSOP) doped with europium (Eu) in their iron oxide core (Eu-VSOP) and their unambiguous qualitative and quantitative detection by fluor...
