background nowadays, removal of heavy metals from the environment is an important problem due to their toxicity. objectives in this study, a modified method was used to synthesize chitosan-coated magnetite nanoparticles (ccmn) to be used as a low cost and nontoxic adsorbent. ccmn was then employed to remove hg2+ from water solutions. materials and methods to remove the highest percentage of mer...

In the present study, the application for the removal of phenylalanine by using two nano sorbents, namely, cetyltrimethylammonium bromide –Coated and BKC (benzal-conium chloride)-Coated Fe3O4 nanoparticles was investigated. Solid-phase extraction (SPE) and ultra violet–visible spectroscopy were used for studying the removal ability of each nano-sorbent in this study. Scanning Electron Microscop...

Core-shell magnetic nanoparticles have received significant attention recently and are actively investigated owing to their large potential for a variety of applications. Here, the synthesis and characterization of bimetallic nanoparticles containing a magnetic core and a gold shell are discussed. The gold shell facilitates, for example, the conjugation of thiolated biological molecules to the ...

Magnetic nanoparticle-mediated intracellular hyperthermia has been a largely experimental modality of hyperthermia, but this treatment modality has the potential to achieve tumor targeted heating without any side effects. The technique consists of targeting magnetic nanoparticles to tumor tissue and then applying an external alternating magnetic field to induce heat generation by the magnetic n...

Biofilms formed by fungal organisms are associated with drastically enhanced resistance against most antimicrobial agents, contributing to the persistence of the fungi despite antifungal therapy. The purpose of this study is to combine the unique properties of nanoparticles with the antimicrobial activity of the Rosmarinus officinalis essential oil in order to obtain a nanobiosystem that could ...

The present study synthesizes a novel adsorbent by coating Fe3O4 magnetic nanoparticles with amino functionalized mesoporous silica. The FTIR spectrums indicate that silica has been successfully coated on the surface of Fe3O4 and 3-aminopropyl tri methoxysilane compound have been grafted to the surface of silica-coated Fe3O4. The XRD analysis shows the presence of magnetite phase with cubic spi...

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...

biomedical applications of superparamagnetic iron oxide nanoparticles (spions) requiring precise control over their physical and magnetic properties, and proper surface treatment. here we report a practical and effective electrochemical strategy for preparation of the polymer coated spions. in this strategy, in situ polymer coating on the surface of spions was achieved through electrodeposition...
