Iontophoresis is based on the constant electric current to run charged drug molecules over the skin by means of electrophoresis as well as electroosmosis [7].
The process, says Athmer, was modeled off of a similar technique called electroosmosis, which has been used successfully in Kentucky, Ohio, and Wisconsin to clean soil of industrial solvents, such as trichloroethylene.
Among the requirements for the proton exchange membrane, that are used in water electrolysis, are high proton conductivity, low electron conductivity, low permeability of the gases (hydrogen and oxygen), high chemical stability in the acidic media, providing high speed electrode reactions, mechanical strength in the dry and humid condition, minor water transport across the membrane by diffusion and electroosmosis effects, as well as availability of materials and low production cost.
Electroosmosis is based on the electrokinetic effects of an electric field on porous systems as a result of the formation of a double electrical layer at a solid-fluid interface.
EMDA/iontophoresis, with the topical application of verapamil or verapamil plus dexamethasone, is thought to enhance transcutaneous absorption of the drugs via electrophoresis, electroosmosis, or enhanced diffusion using surface-delivered heat or current (Greenfield, Shah, & Levine, 2007).
Por otro lado, la limitada solubilidad de los metales en los suelos es otro inconveniente que esta siendo resuelto con el uso de quelantes u otros surfactantes en el suelo o en el agua, o con la combinacion de la fitoremediacion con tecnicas in situ como la electroosmosis para estimular la movilidad de los metales hacia la planta.
He provided a theoretical and experimental framework, drawing from electrohydrodynamics, electroosmosis, and normal-mode stability analysis, to explain the physics behind commonly seen electrokinetic flow instabilities.
The emphasis is on simulating direct-current electrokinetic phenomena such as electroosmosis, electrophoresis, dielectrophoresis, and induced-charge electrokinetics; these phenomena have been widely used to manipulate fluids and particles in microfluidic and nanofluidic devices for various applications.
Irrespective of the type of microelectrodes used, the AC electrokinetic effects involved in the transport and trapping of particles are DEP, electrothermal flow (ETF), and electroosmosis.
