The combination of Tip-Enhanced Raman Spectroscopy with real-time surface characterization in one experimental setup shows great promise as a method for precise local measurement of spatially confined systems. After employing an AFM with an etched [1] nano-apex scanning tip made of Ag or Au[2] to gain structural information one can immediately use the same tip to substantially increase Raman activity at a particular point of interest. Single molecules trapped near the surface of nano-porous oxidized silicon and alumina can be investigated using this finely tunable, highly directed approach.
