The central dilemma in label-free situ surface-enhanced Raman scattering (SERS) for monitoring of heterogeneously catalyzed reactions is the need plasmonically active nanostructures signal enhancement. Here, we show that assembly catalytically transition-metal nanoparticles into dimers boosts their intrinsically insufficient plasmonic activity at monomer level by several orders magnitude, thereby enabling SERS various important single-dimer level.
