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.
Seventeen chapters cover basic concepts, governing equations, basic flow solutions, hydraulic resistance and compliance, diffusion, time-dependent flow, capillary effects, electrohydrodynamics, electroosmosis, dielectrophoresis, magnetophoresis, thermal transfer, two-phase flow, complex flow patterns, acoustofluidics, optofluidics, and nanofluidics.
Design-modeling tools are needed that rapidly simulate the complex underlying phenomena such as electroosmosis, electrophoresis, sample dispersion, mixing, and biochemical reactions without significantly compromising accuracy (1-5).
High-resolution separations based on electrophoresis and electroosmosis.
In situ experiments on low permeability soils provide evidence that pump-and-treat flow rates can be increased using electroosmosis in conjunction with emplacement of granular graphite within hydraulic fractures (Murdoch and Chen 1997).
Worn like a wrist watch, the GlucoWatch uses electroosmosis (a low level of electric current) to extract glucose into the GlucoPad(TM), a disposable pad worn beneath the device.
Navy during the war, later met a number of German engineers who told him that this use of electroosmosis was fairly common.
A significant limitation of electrophoretic mobility and streaming potential measurements, both classified under electroosmosis techniques, is that only an average value of the zeta potential/streaming potential is detected--regardless of whether the surface charge distribution is homogeneous or otherwise.
Furthermore, DNA hybridization buffers often contain high concentrations of salt that reduce the electroosmosis effect and make the EOP a less effective approach (16).
