Surfactant free superparamagnetic iron oxide nanoparticles for stable ferrofluids in physiological solutions.
A process is reported to obtain a nanoparticle sol from co-precipitated iron oxide particles without using any surfactant. The sol - a true ferrofluid - is not only stable over a wide range of pH but also in physiological solutions. This is a decisive step towards biomedical applications where nanoparticle agglomeration could so far only be prevented by using unwanted surfactants.

In this study, magnetic iron oxide nanoparticles (Fe3O4) with the size range of 20-30 nm were prepared by the modified controlled chemical co-precipitation method from the solution of ferrous/ferric mixed salt-solution in alkaline medium. In this process polyethylene glycol was used as a surfactant to prevent the solution from agglomeration. The prepared magnetic nanoparticles were characterize...
متن کاملWashing effect on superparamagnetic iron oxide nanoparticles.
Much recent research on nanoparticles has occurred in the biomedical area, particularly in the area of superparamagnetic iron oxide nanoparticles (SPIONs); one such area of research is in their use as magnetically directed prodrugs. It has been reported that nanoscale materials exhibit properties different from those of materials in bulk or on a macro scale [1]. Further, an understanding of the...
متن کاملSize-tunable synthesis of stable superparamagnetic iron oxide nanoparticles for potential biomedical applications.
Dextran-coated superparamagnetic nanoparticles (MNPs) have widespread biomedical applications. The superparamagnetic behavior, specifically regulated size, and smooth morphology are crucial requirements for essentially all of these applications. Presented herein is an innovative double-coating strategy that would allow for a size-controlled synthesis of MNPs. Small monocrystalline iron oxide na...
متن کاملCitrate capped superparamagnetic iron oxide nanoparticles used for hyperthermia therapy
Superparamagnetic magnetite nanoparticles (MNP) of about 10 nm were designed with proper physicochemical characteristics by an economic, biocompatible chemical co-precipitation of Fe and Fe in an ammonia solution, for hyperthermia applications. Synthetic methodology has been developed to get a well dispersed and homogeneous aqueous suspension of MNPs. Citric acid was used to stabilize the magne...
