Separation of micro particle in microfluidic devices using insulator-based Dielectrophoresis mechanism

چکیده
Separation of micro particle is an important issue in microfluidic devices. In this paper we present separation of 10 (um) and 15 (um) micro particles on one-step and multi-step insulator-Dielctrophorsis (iDEP) as numerically. For this purpose, Laplace and Navier-Stokes equations are solved with stationary-state. In following, particle trajectory was obtained with regarding dielectrophoresis and electrokinetice forces in time-dependent manner. Both of designed devices have similar results in particle tracing under electric potential 150 and 170 (v) at inlets, but maximum electric field in multi-step insulator is less than one-step and therefore produces less Joule heating that is important in separation of bio particles.

Dielectrophoresis is a non-destructive, label-free method to manipulate and separate (bio-) particles and macromolecules. The mechanism is based on the movement of polarizable objects in an inhomogeneous electric field. Here, microfluidic devices are reviewed that generate those inhomogeneous electric fields with insulating posts or constrictions, an approach called electrodeless or insulator-b...

ABSTRACT We present an experimental and numerical study of Joule heating in a polymeric insulator-based dielectrophoresis (iDEP) device. In this study, we used a microscale thermometry technique based upon the temperature-sensitive fluorescence of Rhodamine B dye to monitor the fluid temperature within our iDEP microfluidic devices. We then complemented our experiments with 3D finite element si...

Insulator-based dielectrophoresis (iDEP) is a powerful tool for separating and characterizing particles, yet it is limited by a lack of quantitative characterizations. Here, this limitation is addressed by employing a method capable of quantifying the DEP mobility of particles. Using streak-based velocimetry the particle properties are deduced from their motion in a microfluidic channel with a ...
