UCLA researchers have developed a novel method termed electrode dewetting on dielectric (EDOD) that has the opposite effect of EWOD. It can be used to move or modify a fluid droplet much like EWOD but does not require a hydrophobic surface as EWOD does. The result is also opposite as it reduces the contact area (dewetting) between a liquid droplet and surface while EWOD increases the contact area (wetting) between liquid droplet and surface.
Background Electrode wetting on dielectric (EWOD) is a well-known effect that involves application of electric field to move or modify a fluid droplet. It is most commonly utilized in biomedical devices that require manipulation of small liquid volumes (on the order of 400nL). However, its main limitation is that it requires a hydrophobic surface. Since most synthesized or natural surfaces are hydrophilic, the dielectrics are coated with a hydrophobic material that often reduces the shelf life of the dielectric, is prone to failure and is costly.
