Plasmonically active tip can probe surface-sensitive chemical reactions with nanoscale resolution under in situ conditions. We combine AFM or STM with Raman spectroscopy to achieve simultaneous topological and spectroscopic imaging.

Plasmonic nanostructures are developed to enhance Raman scattering at the confined nanogaps. We achieve single-molecule senstivity with well-defined hot spot engineering.
