Extinction spectra of nanocubes supported by a symmetry breaking dielectric substrate are very different from those in solution.  In this work we varied the refractive index of the substrate in order to optimize the refractive index sensitivity (RIS) of supported silver nanocube monolayers. We found that on thin (5-7 nm) silicon films the RIS is characterized by the figure of merit (FOM) for the quadrupolar plasmonic mode as high as 5.0, making silicon supported silver nanocube monolayers a promising sensing platform.
