Colloidal Preparation of γ-Fe2O3@Au [core@shell] Nanoparticles
Published online by Cambridge University Press: 15 February 2011
Abstract
γ-Fe2O3@Au core-shell nanoparticles were prepared through a combined route, in which high temperature organic solution synthesis and colloidal microemulsion techniques were successively applied. High magnification of TEM reveals the core-shell structure. The presence of Au on the surface of as-prepared particles is also confirmed by UV-Vis absorption. The magnetic core-shell nanoparticles offer a promising application in bio- and medical systems.
