In this research, the Magnetite nanoparticles (Fe304) were prepared by coprecipitation of Fe3+ andFE solution in alkaline medium. Two kinds of surfactants, cetyl tri methyl ammonium bromide(CTAB) and cetyl pyridinum chloride (CPC) were used in the synthesis. Fe304 Nanoparticles werecoated with human serum albumin (HSA) and bovine serum albumin (BSA). Characteristics ofcoated magnetic nanopartic...

BACKGROUND We have developed magnetic cationic liposomes (MCLs) that contained magnetic nanoparticles as heating mediator for applying them to local hyperthermia. The heating performance of the MCLs is significantly affected by the property of the incorporated magnetite nanoparticles. We estimated heating capacity of magnetite nanoparticles by measuring its specific absorption rate (SAR) agains...

Magnetite nanoparticles combined with polymers produce white-light emission under multiphoton laser irradiation. Understanding the photonic reaction in magnetite-polymer composites is critical for application of magnetite NPs as photothermal agents. Laser irradiated magnetite nanoparticle-poly(methyl methacrylate) (PMMA) composites exhibit fluorescence due to the carbon double-bond formation re...

This thesis deals with the synthesis, characterisation, and some applications of ferrimagnetic iron oxide nanoparticles. The iron oxide systems presented in this work are Fe3O4, γ-Fe2O3, NixFe3−xO4, CoxFe3−xO4. Iron oxide nanoparticles were prepared using chemical synthesis methods. Nanoparticles with a narrow size distribution were synthesised using zone confinement methods such as nanoemulsio...

The present study reports the fabrication and characterization of a novel nanostructured phyto-bioactive coated rayon/polyester wound dressing (WD) surface refractory to Candida albicans adhesion, colonization and biofilm formation, based on functionalized magnetite nanoparticles and Anethum graveolens (AG) and Salvia officinalis (SO) essential oils (EOs). TEM, XRD, TGA, FT-IR were used for the...

The suitability of magnetic nanoparticles (MNPs) to act as heat nano-sources by application of an alternating magnetic field has recently been studied due to their promising applications in biomedicine. The understanding of the magnetic relaxation mechanism in biocompatible nanoparticle systems is crucial in order to optimize the magnetic properties and maximize the specific absorption rate (SA...

In this study we report the first generation of force by long-term intracellular magnetic nanoparticles (MNP) using a guinea pig middle ear model. Synthesis of magnetite nanoparticles was done using a modified precipitation technique. We used different methods to characterize MNP. The mechanism for internalizing 16 ± 2.3 nm diameter, silica coated, superparamagnetic, MNP was likely magnetically...
