Abstract
The different spectral behaviour of silver surface-enhanced Raman spec troscopy (SERS) substrates roughened electrochemically in and without the presence of an analyte has been shown clearly. These differences a re associated with anomalous local pH conditions within the cavities i n surfaces of high microporosity in the in-situ roughened silver subst rates. In-situ roughened silver electrodes appeared to have a much hig her porosity compared with ex-situ roughened surfaces.
