TFT display panel technology as a base for biological cells electrical manipulation - application to dielectrophoresis

This paper reports for the first time the use of TFT (Thin Film Transistor) technology of display panels for biological cells electrical manipulation. This technology allows to have high density distributed transparent micro-electrodes, independently controllable, covering centimeter-size glass substrates. This technology is much superior to usual micro-technology used for Multielectrode Arrays (MEAs), which allows only millimeter size surface with micro-electrodes, and with a limited number of 64 micro-electrodes maximum. The chosen application, to demonstrate the capability of such technology, is dielectrophoresis on micro-beads and yeast cells.
