Surface-Enhanced Infrared Absorption Substrates

nfrared spectroscopy is an important analytical tool for chemistry, biology, pharmacy, and medicine. Dipole- and Raman-active modes provide key informa-tion about structural and conformational properties of smallmolecular species aswell as larger units, such as proteins or peptides. Unfortunately, the absorption and scatter-ing cross-sections of molecules in the infra-red are relatively low, which requires large quantities for analysis. One way to over-come this problem is the use of surface enhanced methods, such as surface-enhanced Raman spectroscopy (SERS) and surface enhanced infrared absorptio
