AC electroosmosis micromixing on a lab-on-a-foil electric microfluidic device

Efficient mixing of fluids in lab-on-a-chip devices is very important for many biomedical and biochemical applications. Lab-on-a-foil as a novel concept provides method fast prototyping or mass production microfluidic based on thin flexible films materials. In this article, electroosmosis micromixing conducted lab-on-a-foil device. With the electroosmotic flow (EOF), an efficient realized inside microchannel by tooth-shaped planar electrodes. The performance evaluated intensity measurement, frequency sweeping used to identify optimal performance. Furthermore, according local profiles, EOF pattern analyzed provide deep understanding influence rate. amplitude voltage number pairs electrode tooth are also investigated find conditions To best our knowledge, first demonstration AC electric device exploration vertically horizontally microchannels. This study optimize EOF-based micromixer. fabrication cast potential low-cost devices. • Flexible fabricated using plastic films. Local was quantitively studied chip. relative index (RMI) achieves higher than 0.9. RBCs aggregation successfully with continuous flow.
