Abstract

Boron doped diamond (BDD) disk ultramicroelectrodes have been used to sense single nanoparticle (NP) electrocatalytic collision events. BDD serves as an excellent support electrode due to its electrocatalytic inactivity and low background currents and thus can be used to detect the electroactivity of a wide range of colliding NPs, with high sensitivity. In particular, single NP collisions for hydrazine oxidation at Au and Pt NPs were shown to be markedly different.
