CombiMatrix is developing a unique biochip biochip

Small-scale device, analogous to an integrated circuit, constructed of or used to analyze organic molecules associated with living organisms. One type of theoretical biochip is a small device constructed of large organic molecules, such as proteins, and capable of
 system to offer significant advantages over current products on the market. The rapid acceptance of these new products for genetic research has been evidenced by strong demand from the medical research industry for products from companies including Affymetrix (AFFX), Millennium (MLNM), and Incyte (INCY).

The explosion of genomic information in the past few years has spurred the development of new technologies for DNA analysis DNA analysis Any technique used to analyze genes and DNA. See Chromosome walking, DNA fingerprinting, Footprinting, In situ hybridization, Jeffries' probe, Jumping libraries, PCR, RFLP analysis, Southern blot hybridization. . Biochips have emerged as the fastest and most efficient DNA analysis technique, giving researchers the ability to perform hundreds of DNA tests on a sample of genetic material at one time. These genomic tests are being used to discover new disease targets and treatments in the medical industry.

CombiMatrix's biochips are inexpensively produced on existing semiconductor fabrication lines, eliminating the need for expensive photomasks and robots as well as reducing the investment in capital equipment and clean rooms at the company.
