The main problem of protein SERS study is that the protein native structure can be disturbed by its interaction with a metal surface. SERS spectra of oxy- and deoxy- haemoglobin indicated a partial denaturation of haemoglobin when adsorbed on Ag colloidal NPs (Smulevich and Spiro 1985). Biocompatible coating of the metal surface by SAMs of alkanethiols terminated with NH2- or COOH- groups mediating protein immobilization was used to preserve its native structure (Murgida and Hildebrandt 2006). Another way to keep the natural protein structure is the preparation of a specific SERS-active substrate where the protein molecule is more... [Pg.106]

SERS. A phenomenon that certainly involves the adsorbent-adsorbate interaction is that of surface-enhanced resonance Raman spectroscopy, or SERS. The basic observation is that for pyridine adsorbed on surface-roughened silver, there is an amazing enhancement of the resonance Raman intensity (see Refs. 124—128). More recent work has involved other adsorbates and colloidal... [Pg.591]

The substrate is, of course, a necessary component of any SERS experiment. A wide variety of substrate surfaces have been prepared for SERS studies by an equally wide range of teclmiques [ ]. Two important substrates are electrocheniically prepared electrodes and colloidal surfaces (either deposited or in solution). [Pg.1206]

In addition to the many applications of SERS, Raman spectroscopy is, in general, a usefiil analytical tool having many applications in surface science. One interesting example is that of carbon surfaces which do not support SERS. Raman spectroscopy of carbon surfaces provides insight into two important aspects. First, Raman spectral features correlate with the electrochemical reactivity of carbon surfaces this allows one to study surface oxidation [155]. Second, Raman spectroscopy can probe species at carbon surfaces which may account for the highly variable behaviour of carbon materials [155]. Another application to surfaces is the use... [Pg.1214]
