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...
background: the most common metal used in the body is iron and since it may produce ros, it could potentially be a dangerous substance. objectives: regarding the side effects of nanomaterials such as nano iron particles and possibility of environmental contamination including air pollution with nanoscale iron particle, this study was designed to compare the effects of conventional iron oxide wi...
Innate immune cells play a key role in the pathogenesis of multiple sclerosis and experimental autoimmune encephalomyelitis (EAE). Current clinical imaging is restricted to visualizing secondary effects of inflammation, such as gliosis and blood-brain barrier disruption. Advanced molecular imaging, such as iron oxide nanoparticle imaging, can allow direct imaging of cellular and molecular activ...
conclusions ti is an important parameter to consider in the relationship between si and nanoparticle concentrations. an increase in ti leads to a decrease in the range of linearity. results the results indicate that si depended on the concentration of nanoparticles and ti. in addition, si increased by increasing the tis ranging from 200 to 400 ms for all studied concentrations. the linear relat...
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...
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...
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...
O G Inorganic Nanoparticles for MRI Contrast Agents R E S By Hyon Bin Na, In Chan Song, and Taeghwan Hyeon* S R E P O R T Various inorganic nanoparticles have been used as magnetic resonance imaging (MRI) contrast agents due to their unique properties, such as large surface area and efficient contrasting effect. Since the first use of superparamagnetic iron oxide (SPIO) as a liver contrast agen...
In this Letter, we report, for the first time, using polymer single crystal as magnetically recoverable support for nanoparticle catalysts. This catalyst system is composed of polymer single crystal, platinum nanoparticles, and iron oxide nanoparticles, which act as support, catalysts, and magnetic responsive materials, respectively. Platinum nanoparticles and iron oxide nanoparticles were bond...
