BACKGROUND AND METHODS Magnetic iron oxide nanoparticles were prepared using a sonochemical method under atmospheric conditions at a Fe²⁺ to Fe³⁺ molar ratio of 1:2. The iron oxide nanoparticles were subsequently coated with chitosan and gallic acid to produce a core-shell structure. RESULTS X-ray diffraction demonstrated that the magnetic nanoparticles were pure Fe₃O₄ with a cubic inverse sp...

Polycrystalline iron phosphide coated iron oxide and hollow iron phosphide nanoparticles were synthesized by sonichemistry. Structure analysis indicated that the diameters of these nanoparticles were less than 14 nm, and the core–shell and hollow nanoparticles are Fe3O4–FeP and FeP, respectively. Magnetic measurement demonstrated that both the core–shell Fe3O4–FeP and hollow FeP nanoparticles e...

Monodisperse small iron oxide nanoparticles functionalized with dendritic polyglycerol (dPG) or dendritic polyglycerol sulfate (dPGS) are prepared. They are highly stable in aqueous solutions as well as physiological media. In particular, oleic acid capped iron oxide particles (core diameter = 11 ± 1 nm) were modified by a ligand exchange process in a one pot synthesis with dPG and dPGS bearing...

Enshrined in this review are the biogenic fabrication and applications of coated and uncoated iron and iron oxide nanoparticles. Depending on their magnetic properties, they have been used in the treatment of cancer, drug delivery system, MRI, and catalysis and removal of pesticides from potable water. The polymer-coated iron and iron oxide nanoparticles are made biocompatible, and their slow r...

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...

A new kind of magnetic induction heating materials-carbon coated iron nanoparticles(CCINS) was prepared by arc method and they were used for cancer therapy. The measurement of nanomaterials revealed that they are super-paramagnetic and exhibit a very strong induction heating ability.The magnetic induction heating property was measured by the conduction by Bio-heat method. Heating effect of pig ...

Although iron oxide magnetic nanoparticles (MNP) have been proposed for numerous biomedical applications, little is known about their biotransformation and long-term toxicity in the body. Dimercaptosuccinic acid (DMSA)-coated magnetic nanoparticles have been proven efficient for in vivo drug delivery, but these results must nonetheless be sustained by comprehensive studies of long-term distribu...

Iron oxide impregnated casein nanoparticles (IOICNPs) were prepared by in-situ precipitation of iron oxide within the casein matrix. The resulting iron oxide impregnated casein nanoparticles (IOICNPs) were characterized by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), Vibrating sample magnet...
