Site-specific spectroscopy is critical for a molecular-level understanding of the mechanisms and dynamics of the inhomogeneous chemical processes crucial for catalysis, surface and interfacial chemistry, and membrane protein dynamics in living cells. Surface enhanced Raman scattering (SERS) spectroscopy and microscopy combined with atomic force microscopy (AFM) using metal-coated AFM tips have proven to be powerful in spectroscopic analysis of inhomogeneous processes, providing correlated topographic and spectroscopic information from nanoscale-specific sites under highly heterogeneous environments. It has been recently observed that SERS spectral fluctuations are pertinent to the site-specific spectroscopy and microscopy.
