... frequencies and bandintensities of vibrational transitions represent a uniquefingerprint of the specific conformation of a molecule[10]. Both techniques, however, are associated with lowsensitivity and ... selectivity and sensitivity for thecofactor of the immobilized proteins is only possible with nanostructured Ag for direct excitation of surfaceplasmons down to 400 nm. With the recent discovery of ... also reflect alterations in thecoordination sphere, such that these marker bandsallow monitoring equilibria and dynamics of the spin,coordination and ligation configuration of cyto-chrome c [10,27].Third,...
