Abstract
The present invention relates to filler fluids for droplet operations. According to one embodiment of this aspect, a droplet microactuator including an opaque filler fluid and a transparent droplet thereon is provided. The droplet microactuator may further include a first substrate comprising electrodes configured to effect electrowetting mediated droplet operations on a surface of the first substrate; a second substrate spaced apart from the surface of the first substrate by a distance sufficient to define an interior volume between the first substrate and second substrate; and wherein the droplet and the filler fluid are in the interior volume, and wherein the droplet is surrounded by the filler fluid and arranged with respect to the electrodes in a manner which permits electrowetting mediated droplet operations to be effected on the droplet using the electrodes.
