Abstract

Tip-enhanced spectroscopies have attracted considerable attention due to the capability of nanoscale optical characterization. Here, we demonstrated multimodal tip-enhanced vibrational spectroscopy for nanoscale analysis and imaging. A metallic probe tip was utilized to locally enhance not only Raman scattering but also IR absorption of sample molecules. Simultaneous detection of nano-Raman and nano-IR signal enabled us to elucidate nanoscale physicochemical properties of a variety of nanomaterials such as polymer thin films, self-assembled monolayers and biomaterials.
