Atomic Force Microscopy (AFM) associated to Raman spectroscopy has proven to be a powerful technique for probing chemical properties at the nanoscale. TERS in liquids will bring promising results in in-situ investigation of biological samples, catalysis and electrochemical reactions.
This application note reveals the key instrumental details to succeed in TERS measurements in liquids using side illumination/collection geometry. Such capability aims at bringing breakthroughs in many applications such as heterogeneous catalysis, electrochemistry, cellular biology and biomaterials. In this note, nanoscale chemical imaging of graphene oxide flakes and carbon nanotubes immersed in water is demonstrated with a TERS resolution down to 20 nm along with true non-contact AFM images.
