Kinetics of electrically and chemically induced swelling in polyelectrolyte gels
TL;DR: In this paper, a macroscopic continuum model is presented to predict the kinetics of swelling in polyelectrolyte gel membranes induced by augmentation of electrostatic swelling forces arising from membrane fixed charge groups.

TL;DR: In this article, a method of dynamically controlling the transport of a molecule across a polyelectrolyte membrane was proposed, whereby chemical modulation of the electrostatic swelling forces in the polyelectron membrane results in large changes in permeability and selectivity and a transmembrane electric field having electroosmotic, electrophoretic and electrostatic effects combine to allow the selective transport of the molecule across the membrane.

Contributions of Fluid Convection and Electrical Migration to Transport in Cartilage: Relevance to Loading
TL;DR: The electrophoretic contribution to solute flux, which is relevant to the presence of intratissue streaming potentials induced during loading in vivo, is studied, confirming that fluid convection is most important for large solutes.
Selective augmentation of macromolecular transport in gels by electrodiffusion and electrokinetics
TL;DR: Application of an electric field across polyelectrolyte hydrogel membranes can promote membrane charging and swelling, drive electro-osmotic convection, and produce electrophoresis of charged solutes within the membrane, suggesting a new separation technique based on the size and charge of the solutes.
Dynamic membranes for protein transport: chemical and electrical control
TL;DR: Trans-membrane electric fields and changes in the composition of the electrolyte bath enable selective control of the transport of fluorescently labelled proteins and neutral solutes across polymethacrylic acid and polyacrylamide membranes.
