1. A method of conducting a droplet-based enzymatic assay, the method comprising:

  • (a) providing a droplet actuator;

    (b) providing on the droplet actuator;

    (i) a droplet comprising an enzyme of interest;

    (ii) a droplet comprising a substrate which is potentially modified in the presence of the enzyme;

    (c) executing droplet operations on the droplet actuator to combine the droplet of (b)(i) with the droplet of (b)(ii), thereby yielding an assay droplet;

    (d) detecting modification of the substrate by the enzyme in the assay droplet on the droplet actuator.
