These techniques have provided in situ information related to the synthesis of AgNPs by cyclic voltammetry. With a marker, such as cyanide anion (CN–), Raman spectroscopy has allowed us to study all changes that take place on a platinum electrode surface during the AgNP electrodeposition process. Raman spectra show different SERS behavior depending on the NPs generated. UV–vis absorption spectroelectrochemistry yields information on the changes in AgNP plasmon band during their electrodeposition while Raman signal is highly correlated with the kind of NPs generated. The methodology used in this work demonstrates that SERS effect depends strongly on nanoparticle size and shape Junta de Castilla y Leon (GR71, BU349-U13) and Ministerio de Economia y Competitividad (CTQ2010-17127) is gratefully acknowledged.
