Biocompatible and long-circulating (maghemite/poly(d,l-lactide-co-glycolide))/chitosan (core/shell)/shell nanoparticles with promising theranostic applications (biomedical imaging hyperthermia) against cancer.
Rapid microtiter assays that utilize the time-resolved fluorescence resonance energy transfer or quenching of dye-labeled proteins adsorbed onto the surfaces of polystyrene or maghemite nanoparticles have been developed for the detection and quantification of trace amounts of surfactants at concentrations down to 10 nM.
Neocuproine has been covalently bound to silica-coated maghemite (γ-Fe2O3) magnetic nanoparticles (MNPs) by a phenyl ether linkage. The resulting MNPs are able to remove Cu(II) from 12 ppm aqueous solution with an extraction efficiency of up to 99% at pH 2.
To shed light on the origin of colloidal stability in ionic liquids,we focus on a model colloidal system (maghemite nanoparticles) in which surface charge and counterion nature can be controlled at will. We thus evidence the crucial role of interfacial features on dispersion quality in a standard ionic liquid, ethylammonium nitrate.
Reasoning of particular mechanism anomalous thermal transport behaviors is not identified yet for the nanofluids. In this research, conductivity maghemite (MH) nanoparticles dispe...
Ferrofluids based on maghemite nanoparticles (NPs), typically 10 nm in diameter, are dispersed an ionic liquid (1-ethyl 3-methylimidazolium bistriflimide – EMIM-TFSI).
OBJECTIVE Cell therapies have emerged as a promising approach in medicine. The basis of each therapy is the injection of 1-100×10(6) cells with regenerative potential into some part of the body. Mesenchymal stromal cells (MSCs) are the most used cell type in the cell therapy nowadays, but no gold standard for the labeling of the MSCs for magnetic resonance imaging (MRI) is available yet. This w...
