Magnetic particle imaging has emerged as a new technique for the visualization and quantification of superparamagnetic iron oxide nanoparticles. It seems to be a very promising application for cardiovascular interventional radiology. A prerequisite for interventions is the artifact-free visualization of the required instruments and implants. Various commercially available catheters, guide wires...

Background & Aims: In spite of frequent produce and use of magnetic nanoparticles in biological fields, there are few studies on their side effects, especially under in-vivo conditions. Method: In this research, the effect of the single-dose intraperitoneal injection of DMSA (dimercaptosuccinic acid) coated magnetic iron oxide nanoparticles (Fe3O4) in different doses (50, 100, 200 and 300 mg/kg...

one-pot reaction of aldehydes or ketons with aniline derivatives was performed using nabh4 and fe3o4 magnetic nanoparticles (mnps). the optimum amount of fe3o4 mnps was 5 mol% under solvent free condition. the corresponding products were obtained in good to excellent yields. the magnetically recoverable iron oxide nanoparticles are found to be efficient for synthesis of amine derivatives. these...

Superparamagnetic iron oxide nanoparticles (SPION), as magnetic resonance (MR) imaging contrast agents or magnetic targeting carriers, have potential applications in diagnostics, imaging, cell and drug/ gene delivery for cardiovascular diseases. SPION are highly magnetic particles that cause magnetic field perturbations, which can be identified on T2* weighted images [1]. Clinically, SPION allo...

Novel tissue-engineered magnetic fibrin hydrogel scaffolds were prepared by the interaction of thrombin-conjugated iron oxide magnetic nanoparticles with fibrinogen. In addition, stabilization of basal fibroblast growth factor (bFGF) was achieved by the covalent and physical conjugation of the growth factor to the magnetic nanoparticles. Adult nasal olfactory mucosa (NOM) cells were seeded in t...

in this report, magnetic iron oxide nanoparticles were synthesized via coprecipitation of fe2+ and fe3+ with ammonium hydroxide, and the surface of synthesized nanoparticles was organically functionalized by commercially available amine coupling agent namely, 3-aminopropyl trimethoxysilane (apts) by using well-known sol–gel method. further reaction of the synthesized fe3o4@apts core-shell magne...

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...

Due to their high integrity, facile surface chemistry, excellent stability, and dual properties from the core and shell materials, magnetic-plasmonic core-shell nanoparticles are of great interest across a number of science, engineering and biomedical disciplines. They are promising for applications in a broad range of areas including catalysis, energy conversion, biological separation, medical...

Iron oxide nanoparticles were synthesized by coprecipitation method using ammonia as precipitation agent. Most researchers usually add ammonia into the iron salt solution but in this work the salt solution drop wise has been added to the ammonia and the new obtained results were compared with those of other researches. Magnetic properties of nanoparticles were measured by VSM. The effect of rea...

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(...
