Show more >The present study compares the near-field and far-field sensitivities of localized surface plasmon resonance (LSPR) sensors. To put into evidence the difference between far-field and near-field sensors, optical extinction measurements have been performed on gold nanoparticle gratings coated with dielectric superstrates of varying thicknesses. The potential of LSPR sensors is usually considered to lie in the near-field regime. Therefore, a comparison of the near-field sensitivities for gold nanoparticle gratings and continuous gold films of 50 nm in thickness is provided. The difference in refractive index sensitivities of both sensors is discussed in relation with the decay length of the evanescent near-field. SPRs sensors are usually considered more sensitive than LSPRs in terms of the m factor, refractive index sensitivity. We argue that the m factor sensitivity can only be defined for thick (15--100 nm) superstrates; for thin superstrates (d < 15 nm), the decay length of the evanescent field must be taken into account to properly compare both sensors.Show less >
