The characteristics of localized surface plasmons （LSPs） are introduced in this paper. The major progress in LSPs in the past few years is briefly surveyed, and some advances of the latest applications in theoretical and experimental aspects are summarized. These advances include surface plasmonic resonance amplification, influences of the shape and size of metallic nanoparticles on the plasmonic resonant spectrum, surface enhanced Raman scattering, plasmon lasers, plasmonic nonlinear effects, localized metallic photothermal effects and corresponding biological applications. The physical mechanism in the light effect and manipulation in nanoscale based on metallic nanostructures are also discussed.
