We present the synthesis of nonspherical magnetic microparticles with multiple functionalities, shapes, and chemistries. Particle synthesis was performed in two steps: polymeric microparticles functionalized homogenously with carboxyl groups were generated using stop-flow lithography, and then in situ coprecipitation was used to grow magnetic nanoparticles at these carboxyl sites. With successi...

objective(s): the aim of this work was to prepare and characterize magnetic nanoparticles (mnps) as theranostic system to act simultaneously as drug carrier and mri contrast agent. chitosan-coated mnps (cmnps) were prepared and loaded with silymarin. silymarin-loaded cmnps were characterized with various techniques and their potential as mri contrast agent was also evaluated. materials and meth...

This study investigated the applicability of polyethylene glycol (PEG-4000) coated Fe3O4 magnetic nanoparticles for the selective removal of toxic pb (II) ion from wastewater. The Fe3O4 magnetic nanoparticles of 24 nm were synthesized using a coprecipitation method and characterized by Scanning electron microscopy (SEM), vibratingsample magnetometer (VSM), and X-ray diffraction (XRD). SEM image...

Abstract Superparamagnetic iron oxide nanoparticles (SPIONs) have attracted the particular interest of scientists from various disciplines since their obtaining to present day. The physicochemical and pharmacokinetic properties SPIONs-containing magnetic nanofluids, applicability in biomedicine, largely depend on stability colloidal system, particle size, size distribution, net moment, phase co...

Abstract A wise selection of tracers is critical for magnetic particle imaging (MPI). Most the current are based on superparamagnetic iron oxide nanoparticles (SPIONs) with a suitable coating. We prepared maghemite cores (γ-Fe 2 O 3 ) by coprecipitation Fe(II) and Fe(III) salts ammonium hydroxide followed oxidation hydrogen peroxide stabilization as an anionic ⊖ or cationic colloid ⨁ ). The wer...

Superparamagnetic Iron Oxide Nanoparticles (SPIONs) prepared by simplified coprecipitation were attractive as MRI contrast agents and drug carriers which could internally be manipulated under the influence of an external magnetic field and also cancer treatment due to additional hyperthermia effects. Problem statement: Macrophage and liver cells are potentially exposed to internal SPIONs, thus ...

In situ cell separation and immobilization of bacterial cells for biodesulfurization were developed by using superparamagnetic Fe(3)O(4) nanoparticles (NPs). The Fe(3)O(4) NPs were synthesized by coprecipitation followed by modification with ammonium oleate. The surface-modified NPs were monodispersed and the particle size was about 13 nm with 50.8 emu/g saturation magnetization. After adding t...

The coating of an active drug, 6-mercaptopurine, into the iron oxide nanoparticles-polyethylene glycol (FNPs-PEG) in order to form a new nanocomposite, FPEGMP-2, was accomplished using coprecipitation technique. The resulting nanosized with a narrow size distribution magnetic polymeric particles show the superparamagnetic properties with 38.6 emu/g saturation magnetization at room temperature. ...
