The electromagnetic behavior of plasmonic nanoparticles is highly dependent on their specific particle size and shape. There are different methods which allow us to fine tune the control over the particle shape and size thus, the materials properties. However, the lack of capability to form reproducible organized structures is still a very important challenge to solve in order to control the plasmonic intercoupling between particles.In this work we report a novel method to produce organized structures of plasmonic nanoparticles in a macroscale range, forming linear parallel arrays1. The plasmonic behavior of these organizations was theoretically and experimentally investigated. Moreover, these structures, were effectively use for sensing using Surface-enhanced Raman scattering (SERS) spectroscopy as highly uniform substrates. Figure 1.
