A ‘hi-tech’ mask with freeze-dried sensors to find Covid within 90 minutes. This is the result achieved by a study coordinated by the Wyss Institute for Biologically Inspired Engineering and the Harvard University School of Engineering and Applied Sciences, published in ‘Nature Biotechnology’. A ‘super mask’ that will require no user intervention other than the push of a button. The ‘super mask’, for now scientists have developed only one fabric, but the goal is clear, “is the result of the integration of synthetic biology in wearable devices and could expand the opportunities for monitoring pathogens – explains the study -. The operation of synthetic circuits generally requires the presence of live, engineered bacteria, which has limited their application in wearable devices. ” The technology developed by the scientists provides “substrates and light and flexible fabrics functionalized with freeze-dried, cell-free synthetic circuits, including tools based on Crispr technology (the ‘cut and sew’ system of DNA). It is capable of detecting metabolites , chemicals and pathogenic nucleic acids “. A big step towards a ‘smart’ mask.
