Clinical Micro Sensors Inc. is taking advantage of the electronic properties of DNA by using bioelectronic detection chips to analyze targets in fields ranging from HIV testing to food purity sampling. The company expects that the inexpensive production cost, portability and versatility of its microchip detection device will leverage the product over competing technologies.

The device, which is about one-sixth the size of a credit card, consists of a conventional circuit board upon which gold microelectrodes are placed. Attached to the microelectrodes are rods of six-carbon rings (phenylacetylene) which the company dubs "molecular wires." These molecular wires in turn are attached to DNA capture probes that are designed to bind a particular desired DNA sequence.
