Electrokinetic Behavior of Micro- and Nano-Particles: Directed Assembly Under Electric Fields


Description:
The directed assembly and control of micro- and nano-particles benefits a diverse set of engineering applications. An externally applied electric field is typically used to manipulate colloids, but a host of electrokinetic phenomena may be at play during these processes. Direct and indirect manipulation of particles is possible with electrophoresis, electroosmosis, dielectrophoresis, electrothermal flows, and induced charge electrokinetic phenomena. Papers both fundamental and applied in nature pertaining to the assembly of colloidal particles via these or closely related physical phenomena will be welcomed. Papers relating to the broad areas of microfluidics and colloidal crystallization are particularly desirable.
