Dielectrophoresis-based discrimination of bacteria at the strain level based on their surface properties.

PLoS ONE, 2013
Insulator-based dielectrophoresis can be used to manipulate biological particles, but has thus far found limited practical applications due to low sensitivity.

Dipolophoresis and Travelling-Wave Dipolophoresis of Metal Microparticles

Micromachines, 2020
We study theoretically and numerically the electrokinetic behavior of metal microparticles immersed in aqueous electrolytes. We consider small particles subjected to non-homogeneous ac electric fields and we describe their motion as arising from the ...

Counterflow dielectrophoresis for trypanosome enrichment and detection in blood [PDF]

, 2012
Human African trypanosomiasis or sleeping sickness is a deadly disease endemic in sub-Saharan Africa, caused by single-celled protozoan parasites. Although it has been targeted for elimination by 2020, this will only be realized if diagnosis can be ...

Continuous Particle Separation Driven by 3D Ag-PDMS Electrodes with Dielectric Electrophoretic Force Coupled with Inertia Force

Micromachines, 2022
Cell separation has become @important in biological and medical applications. Dielectrophoresis (DEP) is widely used due to the advantages it offers, such as the lack of a requirement for biological markers and the fact that it involves no damage to ...

Dielectrophoresis model for the colossal electroresistance of phase-separated manganites [PDF]

, 2007
We propose a dielectrophoresis model for phase-separated manganites. Without increase of the fraction of metallic phase, an insulator-metal transition occurs when a uniform electric field applied across the system exceeds a threshold value. Driven by the

Dielectrophoresis-Based SERS Sensors for the Detection of Cancer Cells in Microfluidic Chips

Biosensors, 2022
The detection of freely circulating cancer cells (CTCs) is one of the greatest challenges of modern medical diagnostics. For several years, there has been increased attention on the use of surface-enhanced Raman spectroscopy (SERS) for the detection of ...

Dielectrowetting Driven Spreading of Droplets [PDF]

, 2011
The wetting of solid surfaces can be modified by altering the surface free energy balance between the solid, liquid, and vapor phases. Here we show that liquid dielectrophoresis induced by nonuniform electric fields can be used to enhance and control the
