An analytical model for the prediction of microdrop extraction and splitting in digital microfluidics systems

摘要

Digital microfluidics, especially electrowetting on dielectric (EWOD) has gained momentum in the recent years and it is now foreseen to be a promising way to perform many biological processes like DNA or protein manipulation and detection, and cell analysis. It has been shown that surface energy minimization is an adequate approach to predict the behavior of drops on the electrodes. In the light of the minimization theory, we propose a model to determine the conditions under which drop extraction is possible.
