The electrochemical detection of tagged nanoparticlesvia particle-electrode collisions: nanoelectroanalysis beyond immobilisation

Abstract

The use of particle-impact coulometry in identifying and quantifying nanoparticles tagged (or labelled) with electroactive molecules is demonstrated via the detection of 1,4-nitrothiophenol-tagged silver nanoparticles in aqueous dispersion at potentials more negative than −0.17 V (vs.Ag/AgCl, the reduction potential of nitrothiophenol) via monitoring of particle-electrode collisions.
