Abstract
The roughness of a silver electrode was changed by varying the parameters employed in the oxidation–reduction procedure. Investigations of the surface-enhanced Raman scattering (SERS) intensity as a function of parameters of the oxidation–reduction cycle (ORC) procedure and the extent of roughness have been performed. On the basis of these investigations, it is possible to conclude that deep pores on the surface have a greater influence on the SERS signal than the grain size.
