1. A fluidic device comprising:
a plurality of reaction channels in the form of an array, each reaction channel comprising:
a working electrode;
a counter electrode disposed at a distance from the working electrode; and
a channel electrically connected to both the working electrode and the counter electrode, the channel comprising a first end and a second end;
wherein the counter electrodes of each reaction channel are a single structure comprising a plate covering one major surface of the array, and
wherein flow through the plurality of reaction channels is controllable by controlling a voltage applied to the working electrode relative to the counter electrode.
