We report on an experimental characterization of the sensitivity of localized surface plasmons (LSP) to local changes in the refractive index at a nanometer scale. The method is based on forming a polymer mask covering different well defined areas of metallic nanoparticles and measuring the extinction peak shifts associated with the local refractive index changes. The experimental results are shown to correspond well with theoretical simulations. The results indicate that the sensitivity is strongly correlated with the profile of the LSP electric field.
