Gold nanostars display strong electromagnetic field enhancement at their tips, and tip plasmon resonances can be tuned within the visible and near-infrared, which has been applied toward plasmonic molecular sensing. However, the sensitivity can be further increased by linking gold nanostars to other plasmonic nanoparticles and thereby inducing the creation of hot spots. We report the controlled formation of core satellite assemblies comprising a central gold nanostar with gold spheres adsorbed to the tips via Raman active molecular linkers. Surface-enhanced Raman scattering (SERS) was recorded at the level of single gold nanostar-satellite clusters, and the experimental results were compared with detailed electromagnetic simulations.
