摘要：Plasmonic nanostructures hold great promise in the areas of materials science, chemical and biological sensing. They have been intensively investigated owing to their desirable structure-defined electronic and optical properties and considerable catalytic capacities. Localized surface plasmon resonance is associated with the collective oscillation of dielectrically confined conduction electrons in plasmonic nanostructures and is often excited by coupling with electromagnetic radiation, resulting in spatial confinement and localized field enhancement, which have been widely studied for use in plasmon-enhanced spectroscopy, even to a single-nanoparticle level. Notably, plasmonic nanoparticles can serve as nanoelectrodes with great potential in ultra-sensitive electrochemical detection. Thus, in this chapter, we discuss recent advances in the field of single-nanoparticle plasmonic spectroelectrochemistry. We focus on the fundamental theory as well as applications. Finally, the challenges that must be overcome in emerging key areas such as single-nanoparticle sensing and catalysis are highlighted.
