Synthesis of Silica Coated Magnetic Nanoparticles
In this research controlled coating of magnetite (Fe3O4) nanoparticles with SiO2 was investigated. The Fe3O4 nanoparticles were synthesized via chemical co-precipitation and then coated by silica according to Stober method. Effects of tetra ethyl ortho silicate (TEOS) concentration and ethanol to TEOS on the coating thickness were inves...

متن کاملMagnetic hyperthermia and MRI relaxometry with dendrimer coated iron oxide nanoparticles
Introduction: Recently, some studies have focused on dendrimer nanopolymers as an MRI contrast agent or a vehicle for gene and drug delivery. Considering the suitable properties of these materials, they are appropriate candidates for coating iron oxide nanoparticles which are applied to magnetic hyperthermia. To the best of our knowledge, the novelty of this study is the inves...
متن کاملMagnetic Nanoparticles Coated with a Thermosensitive Polymer with Hyperthermia Properties
Magnetic nanoparticles (MNPs) have been widely used to increase the efficacy of chemotherapeutics, largely through passive accumulation provided by the enhanced permeability and retention effect. Their incorporation into biopolymer coatings enables the preparation of magnetic field-responsive, biocompatible nanoparticles that are well dispersed in aqueous media. Here we describe a synthetic rou...
متن کاملMagnetic properties of polypyrrole - coated iron oxide nanoparticles
Iron oxide nanoparticles were prepared by sol gel process. In-situ polymerization of pyrrole monomer in the presence of oxygen in iron oxide ethanol suspension resulted in a iron-oxide polypyrrole nanocomposite. The structure and magnetic properties of the nanocomposites with varying pyrrole concentrations are investigated. The X-Ray diffraction studies indicate the presence of γ − Fe2O3 phase ...
