Abstract

Redox reactions on gold- and silver screen-printed electrodes (SPE) can be monitored electrochemically using cyclic voltammetry (CV) and spectroscopically by electrochemical chemiluminescence (ECL). Alongside conventional anionic ECL, cathionic ECL with in-situ generated, finely-dispersed Au as a co-reagent is also presented. Raman spectroscopy is a powerful technique that can be employed for the detection of ultralow concentrations when promoted by an enhancement of the scattering process. Simple in-situ electrochemical modification of the electrode leads to surface-enhanced Raman intensities.
