Abstract
Core/shell structured iron(Fe)/gold(Au) nanoparticles have been prepared by a reverse micelle method, and their potential application as magnetic resonance (MR) contrast agent investigated. The average nanoparticle size is 19 nm, as determined by x-ray powder diffraction (XRD) and transmission electron microscopy (TEM). Magnetic properties and relaxivities of nanoparticles are presented and compared. The saturation magnetization is 81 emu g-1 Fe for freshly prepared nanoparticles and the particles have high r 1(6.87 mM-1 s-1) when the Fe core is kept from oxidation. These nanoparticles may be used as T1 agents in the unoxidized form.
