By maneuvering of the amount of Au precursors in the galvanic replacement of Ag nanoprisms, colloidal clusters of plasmonic Au nanoparticles with well‐controlled topological parameters were successfully prepared. The link between the particle‐size dependence of the surface‐enhanced Raman scattering activity of the Au nanoparticle clusters and the relative contributions of the areal density and magnitude of field enhancement of hot spots in the Au nanoparticle clusters was also explored. More information can be found in the Full Paper by S. W. Han et al. on page 772 in Issue 10, 2017 (DOI: 10.1002/cnma.201700152).
