Abstract

Tip-enhanced Raman scattering (TERS) microscopy has been regarded as a promising application of plasmonics for nano-imaging and nano-analysis with a nanoscale spatial resolution far beyond the diffraction limit of light. However, TERS microscopy has been still limited to passive measurement of intrinsic molecular properties and functions. Here, we demonstrate active TERS microscopy in association with the local external stimuli, enabling to reversibly control chemical reactions in the vicinity of a plasmonic tip. The active function in TERS microscopy opens up a new approach to actively control molecular properties and functions at nanoscale.
