Plasmonics is the branch of optics devoted to analyse optical configurations where the passage of light to, from through or near metal objects with subwavelength spatial features and the coupling of that light to a second object located a subwavelength distance from the first object. In the recent years, plasmonics has found application in photopolymerization, in the creation of hybrid (metal-polymer) nanostructures and nanophotochemistry. Analogously, the need to characterize spatially resolved chemical components on nanoscale stimulated the possible combination of Scanning Probe Microscopy with Raman spectroscopy. This led to the invention of Tip-Enhanced Raman Spectroscopy, whose use on polymers permits rigorous chemical analysis with nanometer spatial resolution.
