Seed-Mediated Synthesis of Iron Oxide and Gold/Iron Oxide Nanoparticles

Journal of Nanoscience and Nanotechnology, 2011
In this study, we prepared magnetic iron oxide and gold/iron oxide nanoparticles (NPs) and characterized their morphologies and properties by XRD, TEM, EDX, VSM and UV-vis measurements. The magnetite iron oxide NPs of 10 nm were synthesized by coprecipitation of Fe2+ and Fe+3 in the solution of NH4OH and then they were used as seed particles for the ...

Matrix-Iron Interactions in Carbon-Embedded Iron Oxide Nanoparticles

Journal of Nanoscience and Nanotechnology, 2009
This study deals with the interaction between iron oxide nanoparticles and a carbon-rich source (pitch) during the carbonization process, resulting in a carbon material of high added value. The iron oxide nanoparticles were prepared by different procedures in order to obtain Fe2O3 and Fe3O4 with different particle sizes.

Surface oxidation of iron nanoparticles

Applied Surface Science, 2001
Abstract The electrochemical reaction between aqueous ferric chloride solution and Mg powder has been carried out in open atmosphere to prepare iron nanoparticles. Since iron particles get easily oxidised to α-Fe 2 O 3 , γ-Fe 2 O 3 and Fe 3 O 4 , the final product contains the oxides in different proportions with different dimensions depending on ...

Nanoparticle iron–titanium oxide aerogels

Materials Chemistry and Physics, 2007
Abstract Nanostructured iron oxide–titania aerogel materials have been prepared by sol–gel polymerization of iron acetylacetonate with titanium butoxide and supercritical drying. Their structural properties, including particle morphology, crystalline phase, bond linkage and surface area, were varied by addition of ferric oxide into the titania matrix,

Dextran-modified iron oxide nanoparticles

China Particuology, 2007
Abstract Dextran-modified iron oxide nanoparticles were prepared by precipitation of Fe(II) and Fe(III) salts with ammonium hydroxide by two methods. Iron oxide was precipitated either in the presence of dextran solution, or the dextran solution was added after precipitation.

Dendronized iron oxide nanoparticles for multimodal imaging

Biomaterials, 2011
The synthesis of small-size dendrons and their grafting at the surface of iron oxide nanoparticles were achieved with the double objective to obtain a good colloidal stability with a mean hydrodynamic diameter smaller than 100 nm and to ensure the possibility of tuning the organic coating characteristics including morphology, functionalities, physico ...

Superparamagnetic iron oxide nanoparticles with photoswitchable fluorescence

Chemical Communications, 2008
The incorporation of superparamagnetic iron oxide nanoparticles with sulfur-oxidized diarylethene molecules resulted in a novel multifunctional nanosystem, in which the fluorescent performance and flocculation and dispersion are reversibly switched by light irradiation and external magnetic field, respectively.

Iron Oxide Nanoparticles for Breast Cancer Theranostics

Current Drug Metabolism, 2019
Background: Breast cancer is the second leading cause of death in women worldwide. The extremely fast rate of metastasis and ability to develop resistance mechanism to all the conventional drugs make them very difficult to treat which are the causes of high morbidity and mortality of breast cancer patients.
