Characterization of interaction of magnetic nanoparticles with breast cancer cells [PDF]

, 2015
Background: Different superparamagnetic iron oxide nanoparticles have been tested for their potential use in cancer treatment, as they enter into cells with high effectiveness, do not induce cytotoxicity, and are retained for relatively long periods of ...

Vacancy Coalescence during Oxidation of Iron Nanoparticles [PDF]

Journal of the American Chemical Society, 2007
In the present work, we analyze the geometry and composition of the nanostructures obtained from the oxidation of iron nanoparticles. The initial oxidation of iron takes place by outward diffusion of cations through the growing oxide shell. This net material flow is balanced by an opposite flow of vacancies, which coalesce at the metal/oxide interface.

Synthesis and heating effect of iron/iron oxide composite and iron oxide nanoparticles [PDF]

SPIE Proceedings, 2007
Fe/Fe oxide nanoparticles, in which the core consists of metallic Fe and the shell is composed of Fe oxides, were obtained by reduction of an aqueous solution of FeCl3 within a NaBH4 solution, or, using a water-in-oil micro-emulsion with CTAB as the surfactant.

Rheological Properties of Superparamagnetic Iron Oxide Nanoparticles [PDF]

Journal of Engineering Sciences, 2021
The present study focuses on the rheological properties of polyethylene glycol (PEG) modified, positively charged, and negatively charged superparamagnetic iron oxide nanoparticles (SPIONs) at different temperatures. We hypothesized that the surface properties of these nanoparticles in the water did not affect their rheological properties.
