The FRED System
The Field Ready Electrochemical Detector (FRED) is a biosensor platform to detect waterborne contaminants.
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.
The product is available from the manufacturer, FREDsense Technologies.
The detector and package is ~3000 USD, and each sensor can be ~10-20 USD per test.Interview with manufacturer
Goal 6: Clean water and sanitation
Targeted for utilities and industrial applications
The FRED system is manufactured in-house in Canada and has manufacturing partners for device components (assembly is in-house as well).Interview with manufacturer
This product is sold on the manufacturer’s website.
The product has been available for ~4 months, 12 kits have been deployed thus far.Interview with manufacturer
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.
Sensor usage steps
Provided by the manufacturer
Cartridge for water samples
There is a warranty for two years, and the kit has a five-year estimated lifecycle due to needed upgrades to sensors.Interview with manufacturer
