摘　　要：Visualizing individual molecules with chemical recognition is a longstanding target in catalysis,bio-science,and molecular nanotechnology.Molecular vibrations provide a valuable'fingerprint'for this identification.The spectroscopy based on tip-enhanced Raman scattering(TERS)has opened a path to obtain enhanced spectral signals thanks to the strong localized plasmonic field originated at the tip apex.The development of TERS has been driven to push down the spatial resolution to the single-molecule level.However,the best spatial resolution of the TERS imaging reportedVisualizing individual with chemical recognition molecules is a long- standing target in catalysis, bio-sci- ence, and molecular nanotechnology. Molecular vibrations provide a valuable fingerprint ＇ for this identification.
