One intrinsic feature of bimetallic Janus nanocrystals is the surface covered by two spatially separated metals with distinct properties. On account of this feature, bimetallic Janus nanocrystals can serve as a template for the synthesis of other asymmetric nanoparticles via a site-selected chemical reaction.
