1. A droplet actuator comprising:

  • (a) a substrate comprising electrodes arranged for conducting droplet operations on a droplet operations surface of the substrate;

    (b) a filler fluid phase in contact with the droplet operations surface at least partially surrounding a droplet phase comprising a droplet arranged on one or more of the electrodes, the droplet comprising;

    (i) a target substance susceptible to loss from the droplet phase into the filler fluid phase; and

    (ii) an additive which reduces loss of the target substance to the filler fluid phase relative to a corresponding droplet not comprising the additive.
