(Figure Presented) Giving cobalt some stick: A general strategy for the synthesis of 1D assemblies of hollow nanocrystals is presented. Cobalt nanostructures assembled through magnetic dipolar interactions (see scheme) are used as templates for the formation of wires of hollow nanocrystals of CoSe 2 (and Co3S4, CoTe). The wires of hollow CoSe2 nanocrystals are ferromagnetic, with a Curie temperature of 570 K.
