1. A device for controlling an ionic environment in a droplet, comprising:
a dielectric substrate;
a biological sensor mounted to the substrate;
and at least a pair of electrodes mounted to the substrate and electrically isolated from each other and from the sensor, the electrodes having a dentritic surface morphology;
wherein the biological sensor is disposed between the pair of electrodes.
