In order to understand the role of plasma proteins in the rapid liver clearance of dextran-coated superparamagnetic iron oxide (SPIO) in vivo, we analyzed the full repertoire of SPIO-binding blood proteins using novel two-dimensional differential mass spectrometry approach. The identified proteins showed specificity for surface domains of the nanoparticles: mannan-binding lectins bound to the d...

A highly active heterogeneous Fenton catalyst was fabricated by impregnating iron oxide nanoparticles in alumina coated mesoporous SBA-15 silica.

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...

The performance of polymer exchange membrane fuel cells is known to be strongly influenced by the electrochemical reactions occurring in the cathode catalyst layer. The dynamics of the elementary reaction steps in the oxygen reduction reaction on platinum based catalysts are investigated to provide a better understanding of the cathode overpotential. We present a new approach using Dynamic Mont...

Using iron oxide as catalyst, glycerol can be converted to allyl alcohol through a dehydration and consecutive hydrogen transfer.

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...

The performance of silicon for water oxidation and hydrogen production can be improved by exploiting the antireflective properties of nanostructured silicon substrates. In this work, silicon nanowires were fabricated by metal-assisted electroless etching of silicon. An enhanced photocurrent density of -17 mA/cm² was observed for the silicon nanowires coated with an iron sulphur carbonyl catalys...

A novel magnetite nanoparticle-based heterogeneous acidic catalyst [Fe3O4@SiO2@Am-PPC-SO3H] [HSO4] was successfully prepared and characterized by SEM, EDX, TGA, VSM and FT-IR techniques. The magnetically retrievable and sustainable catalyst was investigated in the reaction of aldehyde and o-aminophenol for the synthesis of benzoxazoles. The...
