1. An addressable chip comprising:
- a substrate;
a plurality of counter electrodes formed on said substrate;
a plurality of reference electrodes, each one substantially encircling a respective counter electrode one of said plurality of counter electrodes in the same plane as its respective counter electrodes;
a plurality of working electrodes, groups of said plurality of working electrodes encircling each of said plurality of reference electrodes and electrically isolated from said counter electrodes;
pairs of said counter/working electrodes for interconnection with a voltage source, to generate a potential for detection of chem/biological probe and target molecule interaction proximate a pair of counter/working electrodes.

Abstract
Addressable bio/chem chips include a plurality of isolated test cells, each addressable by at least two electrodes for measuring electrical characteristics of probe/test molecule interactions. In one embodiment, electrodes are located within a channel to allow for four terminal measurement. In another embodiment, electrodes are arranged in rows and columns and interconnected with electrolyte pads used as test sites. In yet another embodiment, electrodes are arranged in cells, with each cell including a counter electrode surrounded encircled by working electrodes.
