Facile Synthesis of Branched Au Nanostructures by Templating Against a Self‐Destructive Lattice of Magnetic Fe Nanoparticles

Self-destruct mechanism: Gold multipods are formed by a galvanic replacement reaction of AuCl with a self-destructive template consisting of a three-dimensional aggregate of magnetic iron nanoparticles. As a unique feature of this system, the template spontaneously falls apart during the reaction to automatically release the resultant gold multipods.
