Abstract We present a topical review of research in the field of metal-coated gold
nanorods. By combining synthetic design strategies with state-of-the art character-
isation techniques (particularly aberration-corrected scanning transmission electron
microscopy) and molecular dynamic simulations, we demonstrate the potential to
gain a fundamental understanding of, and control over, the atomic detail of metal-
metal bonding at the interfaces of core-shell nanorods and nanoparticles. This
analysis is facilitated by making comparisons between the related bimetallic sys-
tems: AuRh, AuPd and AuPt.
