We investigated the near- and far-field response of one-dimensional chains of Au nanoparticles (NPs) fabricated with high structural control through template guided self-assembly. We demonstrate that the density of polyethylene glycol (PEG) ligands grafted onto the NP surface, in combination with the buffer conditions, facilitate a systematic variation of the average gap width (<i>g</i>) at short separations of <i>g</i><1.1nm. The overall size (<i>n</i>) of the cluster was controlled through the ...[more]
