esearchers from MIT and Harvard have demonstrated a cutting-edge biosensor technology by developing a face mask that can detect SARS-CoV-2 in a wearer’s breath within just 90 minutes. The sensor technology can be programmed to detect any kind of virus or toxin and is small enough to be integrated into clothing fabrics.

The biosensor has been in development for several years and is based on a new technology dubbed wFDCF (wearable freeze-dried cell-free).Unlike previously developed biosensors that require the incorporation of living cells, this system extracts and freeze dries the cellular machinery needed to detect organic molecules.
