We investigated the correlation between the localized surface plasmons (LSPs) and the sensitivity in surface plasmon resonance (SPR) biosensors with periodic metallic nanostructures. The SPR signal can be significantly amplified by the localized adsorption of target analytes that overlap with the local enhanced fields. The goal of this paper is to numerically explore the sensitivity characteristics as a result of the interactions between the LSPs and the target localization.
