Adnavance is a molecular diagnostic company focused on development of DNA-based tests using the Company's patented metalized DNA (M-DNA) platform. The Company is headquartered in Vancouver, British Columbia and also maintains a DNA development laboratory in San Diego, CA. M-DNA is based on the conducting properties of hybridized DNA. Under strict reaction conditions, certain metal ions can enter the central core of hybridized DNA and displace the hydrogen bonds forming the equivalent of a metal wire in the center of the DNA and making the DNA highly conductive. The Company uses a microarray of 10-micron electrodes to detect the M-DNA and the inherent ultra-sensitivity arises from the differential change in conductivity between hybridized DNA and metalized DNA. This change in conductivity is so large that it obviates the need for target amplification used in current molecular-based tests. Adnavance scientists were the first to discover the M-DNA phenomenon, and the Company believes its technology platform will open new molecular testing markets.
