Single Entity Electrochemistry: Faraday Discussion

Themes

• Nanoparticles (NPs), nanotubes (NTs) and nanowires (NWs)
• This session will cover recent advances in electrochemistry (especially electrocatalysis) at the single entity level. Attention will focus on: (i) nanoparticle impact studies, which are of growing interest; and (ii) high resolution electrochemical imaging and spectroscopic visualisation of reactions in ensembles of single entities (NPs, NTs, NWs) on surfaces.
• Nanopores and Nanofluidics
• This session will include DNA analysis and sequencing, particle trapping and counting, and fundamental studies of ion current flow (e.g. ion current rectification and electro-osmosis) in nanopores. The scope extends to the use and characterisation of nanopipettes, e.g. in scanning ion conductance microscopy.
• Complex surfaces and reactions at the nanoscale
• This session will cover probing the behaviour of complex processes such as NP nucleation and electrodeposition/dissolution; to understand the behaviour of complex electrodes at the level of single characteristic features such as grains/facets, grain boundaries, step sites, NPs in fuel cell catalyst layers, particulates in battery electrodes etc.
• Molecular electroanalysis: From single molecules to single cells
• The goal of this session is to highlight progress in the transient detection and measurement of small numbers of molecules, either through the use of nanoscale electrochemical cells to trap a few (or one) molecule or the use of microelectrodes and nanoelectrodes to detect (with selectivity) the release of molecules from living cells (e.g. neurotransmitter release from neurons). Work in this area pushes electrochemistry to the limit in terms of low current measurements.
