Abstract

Au Co-ntraire: The growth of gold nanoparticles on magnetic cobalt nanorods could be initiated either selectively on the tips of the nanorods (see picture, left) or nonselectively over the whole nanorod surface (right) by the proper choice of ligand concentration and temperature. Heterogeneous nucleation was selected over galvanic displacement by the choice of the gold(I) precursor.
