DNA repair enzyme analysis on EWOD fluidic microprocessor

Jary D., Chollat-Namy A., Fouillet Y., Boutet J., Chabrol C., Castellan G., Gasparutto D., Peponnet C., CEA, FR

DNA repair enzyme analysis on EWOD fluidic microprocessor An original analytical assay, aimed at monitoring DNA lesions repair activities has been combined to a dedicated microfluidic EWOD (electrowetting on dielectric) microprocessor.The quantification of enzymatic repair activities [...]

Modeling microdrop motion between covered and open regions of EWOD microsystems

Berthier J., Clementz Ph., Roux J-M, Fouillet Y., Peponnet C., CEA-LETI, FR

Digital microfluidics is a promising way to manipulate biological targets like DNA, proteins or cells in very small liquid volumes. The advantages of such devices are the use of lesser quantities of costly reagents, better [...]

Mechanical Behavior of Micro-Drops in EWOD Systems: drop extraction, division, motion and constraining

Berthier J., Clementz Ph., Jary D., Raccurt O., Claustre P., Peponnet C., Fouillet Y., CEA-LETI, FR

We present a novel contribution to the design of electrowetting microdevices (EWOD) by using an energy minimization approach. Altough the dynamics of motion of microdrops by electrowetting may be rapid, it is shown that, due [...]

An Analytical Model for the Prediction of Microdrop Extraction and Splitting in Digital Microfluidics Systems

Berthier J., Raccurt O., Clementz Ph., Jary D., Claustre P., Peponnet C., Fouillet Y., CEA-LETI, FR

In the preceding text submitted to Nanotech 2005, we have demonstrated that surface tension is the dominant force on liquid microdrops in EWOD microsystems and that the problem is mostly topological. Minimization of the surface [...]
