The nanoscale confinement of plasmonic fields, coupled with their high susceptibility to refractive index changes, makes localized surface plasmons (LSPs) an excellent platform for rapid and label-free sensing. However, the small spatial overlap of the LSP fields with the adsorbed analyte dictates t...
