Electrowetting-on-dielectrics (EWOD) devices actuate droplets of volumes up to several microliters using the principle of modulating the intersurfacial tension between an electrode coated with a dielectric layer and a liquid droplet. In this study, we have sought to perform sample preparation for MALDI-TOF detection of chemical and biological warfares using EWOD technology. In this study, electrodes were patterned on the paper with a conducting material and then its surface was coated with a dielectric layer of parylene-C and covered with a Teflon AF thin film to increase hydrophobicity on the surface of the chip. Application of voltage potential to the electrodes reduces the solid-liquid interfacial tension, so resulting in movement of a droplet through a series of electrodes. This result is expected to help one achieve the automation of the detection of chemical warfares. In the poster-session, the detailed experimental setup and the results will be presented.
