Tip-enhanced Raman spectroscopy (TERS) is a powerful technique that integrates the
vibrational fingerprinting of Raman spectroscopy and the sub-nanometer resolution of
scanning probe microscopy (SPM). As a result, TERS is capable of obtaining chemical maps
of analyzed specimens with exceptional lateral resolution. This is extremely valuable for the
study of interactions between molecules and substrates, in addition to structural
characterization of biological objects, such as viruses and amyloid fibrils, 2D polymeric …
