An Automated Platform for Cell Dielectric Spectroscopy
Résumé
This paper focuses on the development of a new automated platform dedicated to cell manipulation and characterization by dielectrophoretic methods. Microelectrode structures powered with computercontrolled AC generators are used to impose several forms of electric field to cells such as non-uniform, rotating or travelling wave, over a wide frequency range. The resulting induced motion is analysed to deduce cell electric parameters. As an illustration of the system capabilities, several electrorotation spectra of single viable and non-viable yeast cells have been measured at a medium conductivity of 1.1 mS.m-1.
