‘Listening to the electrical noise for nanofluidic sensing’
by Adelchi Jacques Asta, Laboratoire PHENIX, Department of Chemistry, Sorbonne University, Paris, France.
Abstract:
Moving from microfluidics, which is now a well-established field, to nanofluidics requires the development of computational tools. Using the Lattice Boltzmann Electrokinetics (LBE) method, we can couple the Navier-Stokes equation with the Poisson-Nernst Planck theory and thus study charged confined fluids at the nanoscale. Electrochemists have begun to use the electrical fluctuations arising from them to extract information on the interfacial phenomena and thus the underlying microscopic processes (e.g. single molecule detection, adsorption/desorption). This requires to be able to model nanocapacitors with a constant potential difference between the two electrodes.
We present here a way to achieve constant potential simulations in the context of LBE. We then couple this method with the moment propagation method…
