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.
