CFDRC has developed sophisticated and advanced simulation tools for analyzing a various liquid-phase DC/AC electrokinetic phenomena including electroosmosis, electrophoresis, ionization, field amplified sample stacking, electrothermal flow, dielectrophoresis etc.. The models account for effects of complex multi-species electro-chemistry as well as associated fluid flow and particulate motion. This expertise can be readily applied to many conventional electrokinetic processes and more recent AC phenomena, particularly in the microfluidics/Lab-on-Chip realm

Physical Models and Capabilities

Both steady and transient electrokinetics are simulated in 3-D domain by solving coupled electrokinetic equations including multi species transport, fluid flow, electrostatics, ionic reaction and ion dynamics, in conjunction with associated particulate motion, bulk and surface electrochemical reaction as well as energy transfer. This comprehensive approach enables analysis of scenarios such as:

• Multi-species Electrokinetic transport including sample dispersion effects.
• Electrophoretic Separation including (capillary electrophoresis, iso-electric focusing and moving boundary electrophoresis)
  
• Sample pre-concentration/stacking
• AC electroosmotic and electrothermal phenomena.
• Dielectrophoretic motion/separation of small particles.
• Large particle/cell (including size/distortion effects) manipulaton using Dielectrophoretic forces
