Introduction: With the increasing development of nanotechnology, nanomaterials are used instead of conventional compounds. One of these nanomaterials that have many applications in the biomedical field, is iron oxide (Fe2O3) nanoparticles and there is not much research on its effects on the physiological features. So in this research, effect of iron oxide nanoparticles on short and long-term...

the use of an inorganic phase in water-in-oil (w/o) microemulsion   has   received considerable attention recently for preparing metal oxide   nanoparticles. this is a technique, which allows preparation of ultrafine   metal oxide nanoparticles within the size range 40 to 80 nm. preparation of   nano zno and cr 2 o 3 studied, investigated in the inverse   microemulsion system. therefore the nuc...

OBJECTIVE The objective of this study was to evaluate the effect of the labeling of umbilical cord vein derived mesenchymal stem cells with superparamagnetic iron oxide nanoparticles coated with dextran and complexed to a non-viral transfector agent transfector poly-L-lysine. METHODS The labeling of mesenchymal stem cells was performed using the superparamagnetic iron oxide nanoparticles/dext...

objective(s):iron oxide nanoparticles have found prevalent applications in various fields including drug delivery, cell separation and as contrast agents. super paramagnetic iron oxide (spio) nanoparticles allow researchers and clinicians to enhance the tissue contrast of an area of interest by increasing the relaxation rate of water. in this study, we evaluate the dependency of hydrodynamic si...

Nanosized iron oxide particles exhibit osteogenic and radiopaque properties. Thus, iron oxide (Fe3O4) nanoparticles were incorporated into a biodegradable polymer (poly-L-lactic acid, PLLA) to fabricate a composite bone screw. This multifunctional, 3D printable bone screw was detectable on X-ray examination. In this study, mechanical tests including three-point bending and ultimate tensile stre...

Background: Despite the wide range of applications, there is a serious lack of information on the impact of the nanoparticles on human health and the environment. The present study was done to determine the range of dangerous concentrations of iron oxide nanoparticle and their effects on mouse embryonic stem cells. Methods: Iron oxide nanoparticles with less than 20 nanometers diameter were en...
