Contrasts between Single nanoparticle and Ensemble Electron Transfer: Oxidation and Reduction of DPPH Nanoparticles in Aqueous Media

Abstract:
The oxidative and reductive electrochemistry of DPPH nanoparticles is studied via the nanoimpacts method and with drop-casted layers used to modify an electrode surface. In the former case the currents associated with single NP impacts are used to measure the electron transfer kinetics, whereas in contrast it is shown that the reduced diffusion caused by the overlap of adjacent diffusion layers in the latter case leads to more electrochemically reversible behaviour.
