Schematic depiction of the synthetic pathway to Au@Ag cuboids: CTAB-stabilized spherical single-crystalline seed nanoparticles are grown into rods using CTAB and AgNO3 as directing agents and HQ as reducing agent. In a second, step the as-prepared gold nanorods are transferred to desired surfactants (BDAC, CTAC) and subsequently overgrown with silver into Au@Ag cuboids.22,48,49,75
