Engineering and functionalizing magnetic nanoparticles have been an area of the extensive research and development in the biomedical and nanomedicine fields. Because their biocompatibility and toxicity are well investigated and better understood, magnetic nanoparticles, especially iron oxide nanoparticles, are better suited materials as contrast agents for magnetic resonance imaging (MRI) and f...

A facile method for synthesis of amino functionalized silica coated Fe3O4 magnetic nanoparticles is introduced. For this purpose, the surface of magnetic nanoparticles (MNPs) was modified with two precursors of silica which produced amine and vinyl functional groups on the surface of magnetic nanoparticles. The modified magnetic nanoparticles were characterized by transmission electron micr...

In this paper, we simulate magnetic hyperthermia process on a mathematical phantom model representing cancer tumor and its surrounding healthy tissues. The temperature distribution throughout the phantom model is obtained by solving the bio-heat equations and the consequent cell death amount is calculated using correlations between the tissue local temperature and the cell death rate. To have a...

Background: Chitosan nanoparticles have become of great interest for nanomedicine, biomedical engineering and development of new therapeutic drug release systems with improved bioavailability, increased specificity and sensitivity, and reduced pharmacological toxicity. The aim of the present study is to synthesis and optimization of chitosan nanoparticles for industrial and biomedical applicati...

the discharge of lead containing effluents into the environment and water bodies is harmful for the human, animals, aquatic flora and fauna. herein, a novel surface engineered magnetic nanoparticle for removing pb2+ ions was studied. after surface modification of the magnetite by 3-amino-propyltriethoxysilane (aptes) magnetic nanoparticles with covalently linked porphyrins were synthesized. two...

a simple and rapid microextraction procedure based on the application of magnetic nanoparticles and hydrophobic 1-hexylpyridinium hexafluorophosphate [hpy][pf6] ionic liquid (il) was applied to trace determination of gatifloxacin. a mixture of [hpy][pf6] and magnetic nanoparticles was injected into the sample solution containing the analyse of interest and a cloudy solution was formed. after ce...

Magnetic nanoparticles offer some attractive possibilities in biomedicine because it has the special physical properties. Magnetic hyperthermia using magnetic nanoparticles requires that the magnetic particles have not only high heating ability in low magnetic field but also to be non-toxic for biomedical use. Although the reports of bulk magnetic materials or Fe3O4 nanoparticles have known for...

the adsorption characteristics of riboflavin onto silver-deposited iron oxide magnetic nanoparticles (ag/fe3o4) have been described. characterization of the synthesized ag/fe3o4 nanoparticles was achieved by ftir spectra, tem image and xrd pattern. the influence of several experimental parameters such as nanoparticles dosage, ph of the sample solution, different orientations of the riboflavin m...

objective(s): over the past two decades, considerable interest has been focused on utilizing biocompatible magnetic nanoparticles (mnps) for biomedical applications. in this study, production of human serum albumin (hsa) nanoparticles using desolvation technique that were simultaneous loaded with high amounts of superparamagnetic iron oxide nanoparticles (spions) and 5-flourouracil (5-fu) was i...
