In this paper a new electrochemical approach for covalent immobilisation of nanoparticles on a solid surface is described. Terminal alkyne modified gold nanoparticles have been deposited on an azide-functionalised glassy carbon surface by electrochemical generation of the Cu(I) catalyst for the Huisgen “click” reaction. The electrochemical catalyst generation offers good control over the process time and the influence of the process time on the surface coverage and the aggregation factor have been investigated. The efficiency of the electroassisted click-chemistry deposition was compared to standard chemical clicking.
