Dielectrophoresis in microfluidics technology.
Dielectrophoresis (DEP) is the movement of a particle in a non-uniform electric field due to the interaction of the particle's dipole and spatial gradient of the electric field. DEP is a subtle solution to manipulate particles and cells at microscale due to its favorable scaling for the reduced size of the system. DEP has been utilized for many applications in microfluidic systems. In this revi...
متن کاملLiquid dielectrophoresis on the microscale
Polarizable liquids respond to a non-uniform electric "eld by collecting preferentially in regions of maximum "eld intensity. This manifestation of dielectrophoresis (DEP) is a wellknown example of the ponderomotive force, with the "eld acting on individual (molecular) dipoles in the liquid. When electrode dimensions are scaled down to &10 to 100 m, liquid DEP makes possible a new type of high-...
متن کاملMetabolic viability of Escherichia coli trapped by dielectrophoresis in microfluidics.
The spatial and temporal control of biological species is essential in complex microfluidic biosystems. In addition, if the biological species is a cell, microfluidic handling must ensure that the cell's metabolic viability is maintained. The use of DEP for cell manipulation in microfluidics has many advantages because it is remote and fast, and the voltages required for cell trapping scale wel...
متن کاملCapillarity and dielectrophoresis of liquid deuterium
The ponderomotive force, exerted upon all dielectric liquids by a non-uniform electric field, can be used for the remote, voltage-controlled manipulation of 10 to 100μL volumes of cryogenic liquids. This liquid dielectrophoretic (DEP) effect, imposed by specially designed electrodes, combines with capillarity to influence the hydrostatic equilibria of liquid deuterium. A simple, one-dimensional...
متن کاملLiquid-in-gas Droplet Microfluidics
Here we demonstrate a novel concept of liquid-in-gas droplet microfluidics by using gas flow as the continuous phase for the production of liquid droplets. Within a specially configured co-flow microfluidic tubing device, a flow of liquid phase has been continuously dispersed into another outer stream of gas phase, producing discrete and monodisperse microdroplets. This process is robust and we...
