Scientists from the University of Strathclyde and the Indian Institute of Technology (IIT) Bombay have demonstrated a low-cost sensor that can detect fragments of the virus responsible for COVID-19 within wastewater.
The technique, published in the journal Sensors and Actuators B: Chemical, could be used to enable widespread monitoring of COVID-19 prevalence in low- and middle-income countries which struggle to conduct mass human testing.The sensor can be used with portable equipment that uses the standard Polymerase Chain Reaction test to detect the SARS-CoV-2 virus, without the need for the expensive chemicals and lab infrastructure needed for real-time quantitative PCR tests.The sensor was tested
