Dielectrophoretic Microfluidic Devices
On the microscale, the dielectrophoretic (DEP) force may be used to control and manipulate sub-microliter volumes of liquid water using co-planar electrodes of very simple design. The basic phenomenology of liquid DEP on the microscale is familiar; water tends to collect in regions where the electric field is strongest. However, because capillarity and surface wetting become stronger as dimensi...
متن کاملA combined Microfluidic/Dielectrophoretic Microorganism concentrator
This project focuses on the development of a microorganism concentrator for pathogen detection applications. A common problem in microfluidic systems is the mismatch between the volume of a sample and the volume that a device, such as a detector, can process in a reasonable amount of time. Concentrators can, therefore, be used in pathogen detection and other microfluidics applications to reduce...
متن کاملMicrofluidic Device for Continuous Dielectrophoretic Separation of Cells in Division
This paper reports on a novel method for on-chip continuous separation of dividing and non-dividing cells based on differences in their dielectric properties. By means of two opposite dielectrophoretic force fields at multiple frequencies, the two populations of cells flowing through the microfluidic device are focused towards distinct equilibrium positions, which can be correlated to their cel...
متن کاملDielectrophoretic tweezers for examining particle-surface interactions within microfluidic devices
The authors present dielectrophoresis DEP -based tweezers that can be used to characterize the interactions between a particle and the surface it is attached to, within a microfluidic device. As a proof of concept, 5.4 m polystyrene beads functionalized by carboxyl group were attached on a bare and poly-L-lysine functionalized oxide surface. Negative dielectrophoresis force was generated using ...
متن کاملAutomated Dielectrophoretic Characterization for Microfluidic Cell Separation Devices
We present a novel analysis technique for automated characterization of particles and cells using dielectrophoresis (DEP). We combine an automated experimental system to measure DEP particle trapping via fluorescence intensity with physically informed computational methods and sophisticated particle models to make robust measurements of DEP force magnitude. The system uses a LabVIEW-controlled ...
