Abstract

We present a seeded-growth method for the encapsulation of star-like FePt nanoparticles with gold shells in aqueous solution, which allows not only further functionalization (such as silica coating) but also the organization of the synthesized core-shell nanoparticles into mesoscopic one-dimensional nanostructures under the influence of an externally applied magnetic field.
