The Field Ready Electrochemical Detector (FRED) is a biosensor platform developed by FREDsense Technologies to detect waterborne contaminants. Modified microbes designed to sense arsenic, manganese, iron, acidity, or other inorganic and organic contaminants are electrochemically detected. Results are ready in about an hour and can be obtained through a 3G, Wi-Fi, or USB connection.

A water sample is added to the cartridge. When the genetically engineered sensor bacteria detects the chemical they cleave a substrate in proportion to the specific chemical to produce a redox active species. The sample then diffuses to a screen-printed carbon electrode surface to undergo a reversible oxidation detected either via cyclic or square wave voltammetry. This electrochemical signal, incubated in the detector, is reported as a chemical concentration either through 3G, Wi-Fi, or USB connection on a computer, mobile device, or server. Tests take about one hour and are available for arsenic, manganese, iron, acidity, or can be customized for other chemicals. No additional chemicals or training is required, and detection is 1 ug/L.
