Abstract

Recently the attention of specialists in surface-enhanced Raman spectroscopy (SERS) has been concentrated on solid structures with regular roughness. There are some advantages of these surfaces in comparison with the electrochemical cells and colloids. In an electrochemical cell the metal heterogeneities are created by the oxidation-reduction cycle (ORC). The shortcoming of this technique is in the large difference in heterogeneities of size and shape and often in the presence of impurities in the cell, that change the adsorption properties of metal. The main disadvantage of the colloids is in their instability which requires the periodic refreshment of suspensions.1 New stable SERS active surfaces with regular heterogeneities have been developed. Surfaces of desirable shape, size and bamps orientation have been obtained using polynuclear membranes.2 These SERS active stuctures provide higher coefficients of Raman enhancement than the silver-coated polystyrene microspheres on filter paper, described earlier .
