Insulator-based dielectrophoresis for the selective concentration and separation of live bacteria in water.
Insulator-based dielectrophoresis (iDEP) was utilized to separate and concentrate selectively mixtures of two species of live bacteria simultaneously. Four species of bacteria were studied: the Gram-negative Escherichia coli and the Gram-positive Bacillus subtilis, B. cereus, and B. megaterium. Under an applied direct current (DC) electric field all the bacterial species exhibited negative diel...
متن کاملJoule 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 کاملSeparation of mixtures of particles in a multipart microdevice employing insulator-based dielectrophoresis.
Dielectrophoresis is the electrokinetic movement of particles due to polarization effects in the presence of non-uniform electric fields. In insulator-based dielectrophoresis (iDEP) regions of low and high electric field intensity, i.e. non-uniformity of electric field, are produced when the cross-sectional area of a microchannel is decreased by the presence of electrical insulating structures ...
متن کاملEffects of electrothermal vortices on insulator-based dielectrophoresis for circulating tumor cell separation.
Insulator-based dielectrophoresis (iDEP) is a powerful technique for separation and manipulation of bioparticles. In recent years, iDEP designs using arrays of insulating posts have shown promising results toward reaching high-efficiency bioparticle manipulation. Joule heating (JH) and electrothermal (ET) flows have been observed in iDEP microdevices and significantly affecting their performanc...
متن کاملSeparation of micro particle in microfluidic devices using insulator-based Dielectrophoresis mechanism
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 an...
