Biosensor NASA’s biosensor works when a single strand of nucleic acid in a target solution comes into contact with a matching strand of nucleic acid attached to the end of an ultra-conductive nanowire or nanotube. The matching strands form a double helix that generates an electrical signal which is used to determine the presence of specific microorganisms in the sample. Because of their tiny size, millions of nanowires can fit on a single biosensor chip allowing identification of very low cell counts. Early Warning has also developed its own intellectual property pertaining to electrochemical biosensing devices, detecting multiple organisms at the same time, detecting molecules over a wide range of concentrations, and mass fabrication methods.

Concentrator Early Warning has developed its own intellectual property pertaining to automatically extracting 10 Liters or more of water and condensing target molecules into a few milliliters of highly concentrated analyte for use with molecular detection.
