Synthesis and cytotoxic evaluation of poly(ethylene glycol)-coated superparamagnetic nanoparticles
The aim of this study was to synthesize superparamagnetic nanoparticles and to
investigate their cytotoxic effects on osteosarcoma cells. Fe3O4 nanoparticles were
synthesized by the hydrothermal method and ...

Immobilization of urease on Fe3O4 magnetic nanoparticles
such as nanoparticles. One of this nanoparticles is Fe3O4 magnetic nanoparticles which are cheap, non-toxic, biocompatible, easy to prepare, fast separated by external magnetic field, nanosize and having high surface area. So, they have found wide applications...
Effect of cation trapping on thermal stability of magnetite nanoparticles
Carbon nanofibers decorated with magnetic nanoparticles as a new sorbent for the magnetic solid phase extraction of selected polycyclic aromatic hydrocarbons from water samples
A novel nano-adsorbent, magnetic carbon nanofibers (CNFs–Fe3O4), was prepared by impregnating magnetic Fe3O4 nanoparticles onto the surfaces of carbon nanofibers based on electrostatic interactions. The resulting nanoparticles ...
oncentration of reactive dyes in water using MnFe2O4 magnetic nanoparticles and their simultaneous spectrophotometric determination by multivariate chemometrics methods
Adsorption techniques are widely used to remove certain classes of pollutants from
waters, especially those that are not easily biodegradable. Dyes represent one of the
problematic ...
Immobilization of α-amylase onto magnetic nanoparticles by shaking method
α-amylase was immobilized covalently on Fe3O4 magnetic nanoparticles via carbodiimide activation. The efficiency of immobilization and residual activity of the immobilized α-amylase was dependent upon the immobilization temperature and mass ratio...
