A related effect has been described for IR spectroscopy - Surface Enhanced Infrared Absorption spectroscopy (SEIRA). However, as the enhancement factors are significantly lower than for SERS and both the required metal particle size and the activation distance between the target molecule and the particle are more than one order of magnitude smaller, no practically applicable SEIRA sensors have been demonstrated up to now. 

The mechanism of dissolution of the Cu UPD layer on Au(lll) has been studied by Ataka etal. [409]. The monolayer comprised Cu in 2/3 and sulfate in 1/3 proportions. It has been found by applying time-resolved surface-enhanced infrared absorption spectroscopy and chronoam-perometry that dissolution proceeds in two steps. In the first step, 1/3 Cu monolayer and all sulfate anions are removed via the Langmuir-type kinetics. In the second step, the rest of Cu is desorbed via nucleation and growth kinetics.

Surface Enhanced Infrared Absorption Spectroscopy (SEIRAS)... 

Instrumentation. In order to employ local enhancement of infrared absorption by surface plasmon polaritons that cause locally enhanced surface electromagnetic fields, a suitable optical arrangement is needed [295]. Surface enhanced infrared absorption spectroscopy can also be observed in the transmission mode [285, 296]. However, since no application of this approach in spectroelectrochemistry has been reported so far, it is not discussed further.

These ions undergo only weak perturbations upon adsorption. Thus, it can be difficult to discriminate species in solution, or in the diffuse doublelayer, from ions at the electrode surface [54]. Better selectivity for adsorbed electrolyte anions has been achieved through use of the surface-enhanced infrared absorption spectroscopy (SEIRAS) technique [22, 54, 89, 90]. Methods for the preparation of quasi-single crystalline thin films are enabling the study of electrolyte adsorption on structurally well-defined surface sites by SEIRAS [22, 89,... 

Over recent years, internal reflectance infrared studies have tended to concentrate on the study of relatively thick films of conducting polymers or layers, (see, for example, the work of Pham and coworkers [49, 50], or Kvarn-strom, Nauer, Neugebauer and coworkers [51-54]) in which sensitivity was not a particular problem, or on the semiconductor-electrolyte interface, (see the work of Chazalviel and coworkers [35, 40, 41]), in which the SPP excitation approach is not appropriate. However, interest has focused again on this phenomenon with the surface-enhanced infrared absorption spectroscopy (SEIRAS) studies of Osawa and coworkers [19, 26, 27, 46, 55, 56], who have combined the application of the Kretschmann configuration with step-scan FTIR spectroscopy to study fast, reversible electrochemical processes on timescales down to microseconds [26, 46, 57-60].

Purely electrochemical or microscopic techniques (see below) only allow a limited insight into the microbial electron transfer processes. Consequently, the use of spectroelectrochemical techniques, i.e., the direct coupling electrochemical and spectroscopic analysis, has been demonstrated. These techniques, including for instance the combination of voltammetry and UV/vis spectroscopy [19], attenuated total reflectance surface-enhanced infrared absorption spectroscopy... 

SERS (Surface Enhanced Raman Scattering) and, more recently, SEIRA (Surface Enhanced Infrared Absorption) spectroscopies have rapidly expanded their field of applications. These techniques are based on the use of noble metal nanoparticles (NPs) supporting Localized Surface Plasmons (LSP). They are extremely attractive due to unique high sensitivity and their potential for molecule-specific sensing technologies utilizing vibrational signatures 1,2).
