Synthesis and Characterization of Hybrid Core-Shell Fe3O4/SiO2 Nanoparticles for Biomedical Applications
The creation of markers that provide both visual and quantitative information is of considerable importance for the mapping of tissue macrophages and other cells. We synthesized magnetic and magneto-fluorescent nanomarkers for the labeling of cells which can be detected with high sensitivity by the magnetic particle quantification (MPQ) technique. For stabilization under physiological condition...
متن کاملSynthesis and Characterization of a Novel Fe3O4-SiO2@Gold Core-Shell Biocompatible Magnetic Nanoparticles for Biological and Medical Applications
Objectives: The study of core-shell magnetic nanoparticles has a wide range of applications because of the unique combination of the nanoscale magnetic core and the functional shell. Characterization and application of one important class of core-shell magnetic nanoparticles (MNPs), i.e., iron oxide core (Fe3O4/γ-Fe2O3) with a silica shell and outer of gold (Fe3O4-SiO2@Gold (FSG)) in Boron Neut...
متن کاملSynthesis and study of structural and magnetic properties of superparamagnetic Fe3O4@SiO2 core/shell nanocomposite for biomedical applications
Objective(s): This paper describes coating of magnetite nanoparticles (MNPs) with amorphous silica shells. Materials and Methods: First, magnetite (Fe3O4) NPs were synthesized by co-precipitation method and then treated with stabilizer molecule of trisodium citrate to enhance their dispersibility. Afterwards, coating with silica was carried out via a sol-gel approach in which the electrostati...
متن کاملSuperparamagnetic Iron oxide-Gold Core-Shell Nanoparticles for Biomedical Applications
Iron oxide nanoparticles are used for contrast enhancement in magnetic resonance imaging (MRI). We have prepared gold-coated iron oxide nanoparticles that show no change in their superparamagnetic behavior as a consequence of coating. Their potential use as MRI contrast agents was investigated by monitoring their T2 relaxation time with concentration. Cytotoxicity of these nanoparticles was als...
