A new mask capable of detecting infection in the COVVI-19 virus

A team of researchers from the Wyss Institute for Biologalely Inspired Engineering from Harvard University and the Massachusetts Institute of Technology (MIT) has found a way to integrate synthetic biology reactions into textiles, creating portable bios that can be personalized fordetect pathogens and toxins and alert the carrier.The team has integrated this technology into standard facial masks to detect the presence of the Sars-Cov-2 virus in the breath of a patient.The realization is reported in Nature Biotechnology.

The Sars-Cov-2 biocaptive is the culmination of three years of work on portable technology without lyophilized cells (WFDCF).The sensors of the facial mask are designed so that they can be activated by the carrier when it is ready to perform the test, and the results are only displayed inside the mask, for the confidentiality of the user.

Biocapters are lyophilized and remain stable for several months, until they are rehydrated.When activated by water, they can interact with their target molecule, which can be any RNA or DNA sequence, as well as other types of molecules, and produce a signal.

Un nouveau masque capable de détecter une infection au virus Covid-19

To demonstrate technology, researchers have created an integrated jacket with around 30 of these sensors.They have shown that a small splash of liquid containing viral particles, imitating exposure to an infected patient, can hydrate lyophilized cellular components and activate the sensor.The sensors can be designed to produce different types of signals, including a visible color change with the naked eye or a fluorescent or luminescent signal that can be read with a portable spectrometer.To produce their facial diagnostic mask, researchers have integratedlyophilized sensors into a paper mask.

Researchers have made a patent on technology and they now hope to work with a company to further develop sensors.The team is actively looking for manufacturing partners who wish to help allow series production to use facial mask to be used for COVID-19, as well as to detect other biological and environmental risks.
