High-density impedance-sensing array on complementary metal-oxide-semiconductor circuitry assisted by negative dielectrophoresis for single-cell-resolution measurement

Gradient in the electric field for particle position detection in microfluidic channels

“…This impedance-based technique provides high throughput which is necessary when dealing with samples of thousands of cells. [16][17][18][19][20][21][22][23][24][25][26][27][28][29] In cell impedance flow cytometry, the position of the cell between the electrodes is very important due to inhomogeneities in the electric field. 30 This could be avoided by flow-focusing the particles in the centre of the electrodes, however, this requires the use of more equipment and larger electrolyte volumes.…”

Recent advances in dielectrophoresis‐based cell viability assessment

“…Cancer cells are a complex group of abnormal cells developed by uncontrolled growing and spreading, resulting in the decreased membrane potential and membrane capacitance. Trapping and sorting of living cancer cells from the dead ones are critical in the field of medical diagnose at an early stage, where leukemia, Hela cells, and other cancer cells are widely employed as the sample cells.…”

An Improved Escherichia Coli Bacterium Detection in Microchannel Based on Dielectrophoresis Impedance Measurements

“…One of the common DEP methods is dielectrophoretic impedance measurement (DEPIM) that can measure impedance changes of the particle in microchannel in the presence of non-uniform applied electric fields. Thus, it is possible to predict and control the movements of particles in microchannel [40][41][42][43].…”
