Microfluidic Pumping by Micromolar Salt Concentrations
Ran Niu, Patrick Kreissl, Aidan T. Brown +5
An ion-exchange-resin-based microfluidic pump is introduced that utilizes trace amounts of ions to generate fluid flows. We show experimentally that our pump operates in almost dei…
Moving Charged Particles in Lattice Boltzmann-Based Electrokinetics
Michael Kuron, Georg Rempfer, Florian Schornbaum +4
The motion of ionic solutes and charged particles under the influence of an electric field and the ensuing hydrodynamic flow of the underlying solvent is ubiquitous in aqueous coll…
Nanoparticle Translocation through Conical Nanopores: A Finite Element Study of Electrokinetic Transport
Georg Rempfer, Sascha Ehrhardt, Christian Holm +1
Recent years have seen a surge of interest in nanopores because such structures show a strong potential for characterizing nanoparticles, proteins, DNA, and even single molecules.…
Selective Trapping of DNA using Glass Microcapillaries
Georg Rempfer, Sascha Ehrhardt, Nadanai Laohakunakorn +4
We show experimentally that a cheap glass microcapillary can accumulate λ-phage DNA at its tip and deliver the DNA into the capillary using a combination of electro-osmotic flow, p…
Limiting Spurious Flow in Simulations of Electrokinetic Phenomena
Georg Rempfer, Gary B. Davies, Christian Holm +1
Electrokinetic transport phenomena can strongly influence the behaviour of macromolecules and colloidal particles in solution, with applications in, e.g., DNA translocation through…
Diffusiophoretic Self-Propulsion for Partially Catalytic Spherical Colloids
Joost de Graaf, Georg Rempfer, Christian Holm
Colloidal spheres with a partial platinum surface coating perform auto-phoretic motion when suspended in hydrogen peroxide solution. We present a theoretical analysis of the self-p…
