Synthesis, characterization and bio-functionalization of magnetic nanoparticles to improve the diagnosis of tuberculosis
(IOP Publishing, 2020)
Mycobacterium tuberculosis is the cause of one of the diseases with the highest mortality and morbidity rate in the Americas and in the world. In developing countries, the diagnosis of tuberculosis (TB) is based on baciloscopy ...
Magnetic Ionic Liquids Produced by the Dispersion of Magnetic Nanoparticles in 1-n-Butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (BMI.NTf2)
(AMER CHEMICAL SOCWASHINGTON, 2012)
This paper reports on the advancement of magnetic ionic liquids (MILs) as stable dispersions of surface-modified gamma-Fe2O3, Fe3O4, and CoFe2O4 magnetic nanoparticles (MNPs) in a hydrophobic ionic liquid, 1-n-butyl ...
Exchange-coupling in thermal annealed bimagnetic core/shell nanoparticles
(Elsevier Science Sa, 2015-06)
In this study we demonstrate that the effective coupling of the magnetic phases in core/shell nanoparticles can be promoted by an appropriate thermal annealing. In this way, the magnetization thermal stability of the hard ...
Assembly of magnetic nanoparticles at a liquid/liquid interface: Catalytic effect on ion transfer process
(Elsevier Science Sa, 2015-11-01)
The adsorption of cobalt (Co) and cobalt–boron (CoxB) magnetic nanoparticles (NPs) at a liquid/liquid interface is examined. The Co NPs have a remanent magnetization while the CoxB is completely demagnetized in the absence ...
