Synthesis, Assembly, Optical Properties, and Sensing Applications of Plasmonic Gap Nanostructures (Adv. Mater. 46/2021)

Abstract

Plasmonic Gap Nanostructures In article number 2006966, Jwa-Min Nam and co-workers review key concepts and advances in synthesis, assembly, optical properties, and sensing applications of plasmonic gap nanostructures. Plasmonic nanogaps produce largely enhanced optical signals from highly localized electromagnetic fields. Control and exploration in the structures and characteristics of the nanogap structures open new possibilities for various applications including surface-enhanced Raman scattering, biosensing, and bioimaging.
