Analysis of electrochemical processes using surface plasmon resonance

We simultaneously employed voltammetry and surface plasmon resonance (SPR) measurements and monitored electrochemical processes on gold electrode. SPR is sensitive not only to the adsorbed layer on the gold electrode, but also to the dielectric properties of the solution phase. Therefore, an electro...

Description
Summary:We simultaneously employed voltammetry and surface plasmon resonance (SPR) measurements and monitored electrochemical processes on gold electrode. SPR is sensitive not only to the adsorbed layer on the gold electrode, but also to the dielectric properties of the solution phase. Therefore, an electrochemically modulated diffusion layer can be detected by SPR. We tested the relationship between the time differential SPR data and the electrode current for two electrochemical processes and confirmed the possibility of using electrochemical SPR measurement.
