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. http://pubs.sciepub.com/wjce/10/1/4/wjce-10-1-4.pdf graduate education / research electrochemistry Raman spectroscopy
