Water is essential to our lives, our industry, and our environment. It is our most precious resource. Despite this, our ability to monitor the quality of our freshwater assets is lacking. The existing tools are expensive and complex, requiring on-site sample collection and processing. This costs time and money, meaning that in many industries sampling is often periodic, and contamination can be missed. FREDsense combines biology and engineering to detect chemicals in your water using a biosensor with an electrochemical output to create a system that is fast, sensitive, and unlike anything else on the market, allowing anyone to know exactly what is in their water.
