Abstract The development of polymeric nanomaterials, combining properties of polymers and superparamagnetic nanoparticles, has potential for biomedical applications, such as treatment of tumors through intravascular embolization and hyperthermia. Therefore, this work aims at development of a new magnetopolymeric fluid formed by magnetic nanoparticles of iron oxide (Fe3O4) coated with chemically modified oleic acid and which were uniformly dispersed in spherical nanoparticles of poly(vinyl pivala...

The objective of this work is to develop and characterize polymeric nanoparticles with core–shell morphology through miniemulsion polymerization combined with seeded emulsion polymerization, aiming at the application in the treatment of vascular tumors via intravascular embolization. The synthesis of the core–shell nanocomposites was divided into two main steps: (i) Formation of the core structure, consisting of poly(methyl methacrylate)/magnetic oxide coated with oleic acid (OM-OA) via miniemul...

Abstract Nanoparticles of iron oxide play an important role on the field of nanotechnology and nanoscience presenting tremendous potential for various applications. Oleic acid has been shown to be a promising coating material, allowing to obtain monodisperse, uniform and stable nanoparticles. However, for certain applications which utilize the encapsulation of magnetic nanoparticles into polymer matrices it becomes necessary to use coating materials which exhibit functional groups in their struc...

Abstract Iron oxide nanoparticles have high saturation magnetization values and their surfaces are easily modified by the insertion of functional groups such as carboxylic acids, surfactants, and polymers. In this work, iron oxide nanoparticles were functionalized with glycerol molecules modified by an esterification reaction with monocarboxylic acid, for their application in the removal of oils in aqueous surface. The nanoparticles were prepared by the coprecipitation method by alkaline hydroly...
