The powerful technology of the CustomArray™ platform combined with CombiMatrix’s advances in electro-chemical detection is meeting a crucial national need. CombiMatrix is revolutionizing detection technologies for biological and chemical threat agents.

CustomArray™, as a CMOS chip, is a versatile transducer that can convert electrical signals into electrochemical reactions at each electrode. Conversely, circuitry on the microarray can convert an electrochemical reaction above an electrode into a signal.

CombiMatrix is now developing electro-chemical based instruments and assays for the genomic identification of biothreat agents (viruses and bacteria) and serological assays for toxins, viruses and bacteria.

Electro-chemical detection turns the microarray into the sensor. Complex, expensive, and less-than-robust optical readers are not needed. Microarray technologies can now be configured into a variety of instrument designs to support fixed and mobile laboratories and stand-alone detection systems.

With over 12,000 electrodes available for individual assay results, CustomArray™ readily supports multiplexed genomic and serological assays against all categories of biothreat agents. CombiMatrix scientists and engineers continue to investigate and develop new detection strategies to counter the known and unknown threats with a reliable, sensitive, and robust detection platform.
