Synthesis and characterization of PVP-functionalized superparamagnetic Fe3O4 nanoparticles as an MRI contrast agent
The magnetite (Fe3O4) nanoparticles (MNPs) coated with poly(N-vinyl pyrrolidone) (PVP) via covalent bonds were prepared as T2 contrast agent for magnetic resonance imaging (MRI). The surface of MNPs was first coated with 3(trimethoxysilyl) propyl methacrylate (silan A) by a silanization reaction to introduce reactive vinyl groups onto the surface, then poly(N-vinyl pyrrolidone) was grafted onto...
متن کاملSynthesis of PVP-coated ultra-small Fe3O4 nanoparticles as a MRI contrast agent.
Ultra-small Fe(3)O(4) nanoparticles were prepared by using the coprecipitation method, in which the polyvinylpyrrolidone (PVP) serves as a stabilizer. The nanoparticles were characterized by means of X-ray diffraction (XRD), transmission electron microscopy (TEM), infra spectrum (IR), X-ray photoelectron spectroscopy (XPS) and in vivo magnetic resonance imaging (MRI) test. The results showed th...
متن کاملSynthesis and evaluation of chitosan manganese-ferrite nanoparticles as MRI contrast agent
Magnetic nanoparticles are the good choice for using in MRI as the contrast agent. Iron oxide particles such as magnetite (Fe3O4) or its oxidized form maghemite (γ-Fe2O3) are the most commonly employed in biomedical applications. In this study, we synthesized and optimized the preparation of chitosan manganese-ferrite nanoparticles (CMn-Fe nps) and evaluated its ability for the mice macrophage ...

متن کاملPotential positive MRI contrast agent based on PVP-grafted superparamagnetic iron oxide nanoparticles with various repetition times
Objective(s): The present study aimed to evaluate the capability of synthesized and modified superparamagnetic iron oxide nanoparticles (SPIONs) as the positive contrast agent in magnetic resonance imaging (MRI) by investigating the effect of repetition time (TR) on the MRI signal intensity. Materials and Methods: SPIONs were synthesized using the co-precipitation method, and their surfac...
