Joule Heating Effects on Insulator-based Dielectrophoresis
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...
متن کاملDevelopment of the resolution theory for gradient insulator-based dielectrophoresis.
New and important separations capabilities are being enabled by utilizing other electric field-induced forces besides electrophoresis, among these is dielectrophoresis. Recent works have used experimentally simple insulator-based systems that induce field gradients creating dielectrophoretic force in useful formats. Among these, juxtaposing forces can generate gradient-based steady-state separa...
متن کاملConcentration of Sindbis virus with optimized gradient insulator-based dielectrophoresis.
Biotechnology, separation science, and clinical research are impacted by microfluidic devices. Separation and manipulation of bioparticles such as DNA, protein and viruses are performed on these platforms. Microfluidic systems provide many attractive features, including small sample size, rapid detection, high sensitivity and short processing time. Dielectrophoresis (DEP) and electrophoresis ar...
متن کاملDielectrophoretic mobility determination in DC insulator-based dielectrophoresis.
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 ...
متن کاملOff-chip passivated-electrode, insulator-based dielectrophoresis (OπDEP)
In this study, we report the first off-chip passivated-electrode, insulator-based dielectrophoresis microchip (OπDEP). This technique combines the sensitivity of electrode-based dielectrophoresis (eDEP) with the high-throughput and inexpensive device characteristics of insulator-based dielectrophoresis (iDEP). The device is composed of a permanent, reusable set of electrodes and a disposable, p...
