This talk will highlight underrated phenomena broadcasted through ultrasensitive surface-enhanced Raman scattering (SERS) and high resolution tip-enhanced Raman scattering (TERS). The ultimate goal of this presentation is to establish that these powerful techniques may be used for much more than mere ultrasensitive chemical detection and nanoscale chemical imaging. Achieving this goal nonetheless necessitates tackling fundamental challenges associated with SERS and TERS, particularly in scenarios where ensemble averaging is no longer appropriate. We identify some of these challenges and describe on-going works aimed at exploring and exploiting the full information content in SERS and TERS.
