The FREDsense system combines biology and engineering to detect chemicals in industrial water. Rather than using expensive machinery that requires technicians or highly trained personnel, FREDsense has developed a biosensor platform to detect water-borne chemicals and contaminants. This platform technology can be developed to detect virtually any chemical that interacts with a living organism. With the ability to test complex samples and not requiring lengthy preparation steps, the FREDsense system is the most flexible sensor suite developed to date. The next generation sensor will expand the FREDSense platform to include three additional high-priority contaminants: heavy metals lead and chromium, and the algal bloom toxin microcystin.
