due to its ability in chemical oxidation of contaminants, iron nanoparticle is a material of choice to remove lead ions from aquatic solutions. in this study a reduction method in solution phase was applied to synthesize thenanoparticles. afterwards, the size of the synthesized particles were confirmed by scanning electron microscopy. it is worth noting that the nanoparticle dose-variations wer...
in this study, we synthesized herceptin conjugated magnetic nanoparticles (hmns) as an alternative probe to discover the levels of her2 (human epidermal growth factor receptor-2) in the surface of cells. these nanoparticles can be used by magnetic resonance imaging (mri) (non-invasive methods) for screening the patients with her2 positive or negative tumors. dextran coated iron oxide nanopartic...
Introduction: Depression is a mood disorder in which feelings of sadness, loss, anger, or frustration interfere with everyday life for one to several weeks. Several studies have shown that iron nanoparticles have neuroprotective and anti-inflammatory effects. This study aimed to evaluate anti-depressive effect of iron nanoparticles in male rats. Methods: Depression was induced by Lipopol...
Given the increased use of iron-containing nanoparticles in a number of applications, it is important to understand any effects that iron-containing nanoparticles can have on the environment and human health. Since iron concentrations are extremely low in body fluids, there is potential that iron-containing nanoparticles may influence the ability of bacteria to scavenge iron for growth, affect ...
Purpose: The presence of tumor-associatedmacrophages (TAM) in breast cancer correlates strongly with poor outcome. The purpose of this study was to develop a clinically applicable, noninvasive diagnostic assay for selective targeting and visualization of TAMs in breast cancer, based on magnetic resonanceI and clinically applicable iron oxide nanoparticles. Experimental Design: F4/80-negativemam...
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...
Folic acid (FA) was conjugated to superparamagnetic iron oxide nanoparticles to develop a tumor specific contrast agent for magnetic resonance imaging (MRI). In this scheme a bifunctional poly(ethylene glycol) (PEG) linker was utilized to both increase biocompatibility and reduce nanoparticle agglomeration. The uptake of nanoparticle-PEG-FA conjugates by folate-receptor (FR) positive MCF-7 cell...
Iron oxide nanoparticles with engineered physical and biochemical properties are finding a rapidly increasing number of biomedical applications. However, a wide variety of safety concerns, especially those related to oral exposure, still need to be addressed for iron oxide nanoparticles in order to reach clinical practice. Here, we report on the effects of chronic oral exposure to low doses of ...
Iron oxide nanoparticle formation in DES was studied in situ across multiple length scales. Initial chloride-containing iron complexes react to form oxygen-rich species which precipitate. Morphology and growth time are defined by solvent composition.
