Harvard researchers create a device installed in the muzzle that tests your breath to detect corona

A team of researchers from the American Harvard University and the American Massachusetts Institute of Technology have come up with an invention that combines two strategies to stop the spread of respiratory diseases, as they created a wearable biosensor, to do the work of the entire laboratory - which is small enough to be installed on a face mask, according to what was published by the “Insider” website. "American.

The innovation works by having a person breathe inside a face mask for 15 to 30 minutes and press the sensor button, and within another 90 minutes, the results of the corona test appear on a reading strip similar to a pregnancy test, and the invention is described in more detail in the journal Nature Biotechnology.

"For everyone who has this diagnostic face mask, you not only prevent the virus from spreading, you actually determine whether they have it relatively quickly," said co-first author Peter Nguyen, a research scientist at Harvard University.

The team extracted and dried the molecular machinery that cells use to identify genetic material such as DNA and RNA.

 Co-first author Louis Swinksen, a postdoctoral fellow at the Wyss Institute, said this information is a "fingerprint" of the sensor to identify the virus, and the sensor is activated at the push of a button, releasing a small amount of water to rehydrate the freeze-dried ingredients.

The same technology can be used to identify other pathogens, such as influenza - down to the individual building blocks of DNA - and it can even differentiate coronavirus variants.

The researchers said the test's sensitivity is comparable to gold-standard RT-PCR tests, and results are showing up relatively quickly.
