In situ external magnetic field was applied during the synthesis of FePt nanoparticles via a chemical solution method. FePt nanoparticle films were prepared on Si by a drop-coating method with and without a magnetic field. Annealing at 700 °C in reductive atmosphere was explored to obtain ferromagnetic FePt L10 phase. The effect of in situ-applied magnetic field on the structure, morphology, an...

background: removing heavy metals from industrial wastewaters by iron nanoparticles has been much noticed in the recent years. chromium is considered as one of the emphasis environmental pollutants. there are high concentrations of chromium in the wastewater of electroplating industries. magnetic iron nanoparticles are used to control and eliminate the heavy metals from industrial effluents thr...

Rapid and accurate measurements of protein biomarkers, pathogens and cells in biological samples could provide useful information for early disease diagnosis, treatment monitoring, and design of personalized medicine. In general, biological samples have only negligible magnetic susceptibility. Thus, using magnetic nanoparticles for biosensing not only enhances sensitivity but also effectively r...

fe3o4 nanoparticles were synthesizedviaa simple chemical reaction between fecl2.4h2o and fe(no3)3.9h2o under nitrogen atmosphere at room temperature, and then nanoparticles were added to cellulose acetate (ca) polymer. the influence of nanoparticles on the thermal properties of ca polymeric matrix was studied using thermogravimetric analysis (tga). nanostructures were characterized by x-ray dif...

Nanocomposite microcapsules with both gold and magnetite nanoparticles in the shell were prepared in a layer-by-layer procedure using biocompatible polyelectrolytes and nanoparticles. The process of a nanocomposite multilayer formation was investigated using a quartz crystal microbalance (QCM). In addition, nanocomposite microcapsules were characterized by atomic force microscopy (AFM), transmi...

a new method for the separation and preconcentration of trace amounts of cadmium in food and water samples by magnetic solid phase extraction (mspe) with fe3o4 magnetic nanoparticles (fe3o4-mnps) and its determination by flame atomic absorption spectrometry has been developed. for this purpose, fe3o4-mnps were synthesized via chemical precipitation method. the extraction of cadmium ions from th...

Controlling the morphology of magnetic nanoparticles and their spatial arrangement is crucial for manipulating their functional properties. The commonly available inorganic processes for the synthesis of uniform magnetic nanoparticles typically require extreme reaction conditions such as high temperatures or harsh reagents, rendering them unsuitable for making functionalized magnetic nanopartic...

We present a systematic study on the preparation, characteration and potential application of Fe3O4 and Fe3O4@SiO2 nanoparticles. Fe3O4 nanoparticles of controllable diameters were successfully synthesized by solvothermal system with tuning pH. The magnetic properties of nanoparticles were measured by vibration sample magnetometer. Fe3O4@ SiO2 nanoparticles were obtained via classic Stöber proc...

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...

In this paper, we have proposed a simple method to covalently conjugate biotin to magnetic nanoparticles, which can be targeted to the tumour sites by using pretargeting approach with avidin or streptavidin. Magnetic nanoparticles of manganese ferrite were synthesized by alkaline coprecipitation of ferric chloride hexahydrate, ferrous sulphate heptahydrate and manganese sulphate monohydrate usi...
