Dielectrophoretic registration of living cells to a microelectrode array.
We present a novel microfabricated device to simultaneously and actively trap thousands of single mammalian cells in alignment with a planar microelectrode array. Thousands of 3 micromdiameter trapping electrodes were fabricated within the bottom of a parallel-plate flow chamber. Cells were trapped on the electrodes and held against destabilizing fluid flows by dielectrophoretic forces generate...
متن کاملDielectrophoretic Characterization of Colloidal Particles Using Angled Microelectrode Arrays
This paper will present a characterization of a microfluidic device with embedded angled microelectrode arrays for the continuous flow-through dielectrophoretic separation of particles. The operation of the device is demonstrated using samples of colloidal latex spheres, achieving 100% particle deflection with low operating voltage of 10V. This characterization is essential for dielectrophoreti...
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 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 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 ...
