1. A droplet microactuator comprising:

  • (a) a first substrate comprising electrodes configured to effect electrowetting mediated droplet operations on a surface of the first substrate;

    (b) a second substrate spaced from the surface of the first substrate by a distance sufficient to define an interior volume between the first substrate and the second substrate; and

    (c) a droplet and a filler fluid in the interior volume, 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, wherein the filler fluid comprises an oil and a surfactant, and wherein the surfactant is provided in an amount which ranges from about 0.001 to about 10% w/w.
