MIT Develops Sensor to Detect 'Forever Chemicals' in Water
A breakthrough sensor offers a quick and cost-effective method for detecting harmful PFAS in drinking water, potentially transforming water safety monitoring.
- MIT chemists have developed a sensor capable of detecting low levels of PFAS, known as 'forever chemicals', in drinking water.
- The sensor uses lateral flow technology and a special polymer to measure PFAS concentrations as low as 200 parts per trillion.
- This innovation offers a faster, cheaper alternative to current PFAS detection methods, which require laboratory testing.
- The device could be beneficial for both consumers wanting to test their drinking water and industries that use PFAS chemicals.
- Researchers are working on a larger-scale device to increase sensitivity and meet EPA advisory levels for PFAS in drinking water.
