摘要: Electrowetting-on-dielectric (EWOD) is a new method for moving liquids in biofluidic chips through electrical modification of the surface hydrophobicity. EWOD-based devices are reconfigurable, have low power requirements, and can handle neutral charged analytes, as well particulates. We show that biomolecular adsorption EWOD minimized by limiting time during which no potential applied choice solution pH electrode polarity. The same approach may be useful controlling other applications hydrophobic dielectric materials. These results demonstrate feasibility implementing fluid actuation chips.
