Improving the rate of silver nanoparticle adhesion to 'sticky electrodes': Stick and strip experiments at a DMSA-modified gold electrode

Abstract

The immobilisation of nanoparticles from solution at a solid surface followed by anodic stripping voltammetry is a simple technique allowing the analysis of nanoparticle concentrations and identity. We report that the modification of gold electrodes with meso-2,3-dimercaptosuccinic acid (DMSA) shows a useful increase in the adsorption rate of silver nanoparticles on a gold substrate showing that the chemical modification of the electrode is analytically advantageous. © 2014 WILEY-VCH Verlag GmbH & Co.
