Engineers at the Massachusetts Institute of Technology and Harvard University have designed an innovative face mask that can diagnose if the wearer is infected with the Covid-19 virus within 90 minutes.
Researchers have developed a wearable biosensor technology that allows the mask to detect the virus through the wearer’s breath. The masks are embedded with tiny, disposable sensors – known as Specific High-sensitivity Enzymatic Reporter unLOCKing, or SHERLOCK – that can also detect the presence of other viruses and infections, according to the research paper.
We have essentially shrunk an entire diagnostic laboratory down into a small, synthetic biology-based sensor that works with any face mask

“We have demonstrated that we can freeze-dry a broad range of synthetic biology sensors to detect viral or bacterial nucleic acids, as well as toxic chemicals, including nerve toxins,” James Collins, professor of medical engineering and science at MIT’s Institute for Medical Engineering and Science, said.
“We envision that this platform could enable next-generation wearable biosensors for first responders, health care personnel and military personnel,” he added.
Users can activate face mask sensors using a button when they are ready to perform the test, which releases water stockpiled around the sensors. Once hydrated, they examine the users’ breath droplets and check for the presence of Covid-19 and other viruses.
Results can be achieved within 90 minutes at the same accuracy levels as a polymerase chain reaction (PCR) test. To ensure the privacy of users’ data, results are only displayed on the rear of the mask.
“We have essentially shrunk an entire diagnostic laboratory down into a small, synthetic biology-based sensor that works with any face mask ... and combines the high accuracy of PCR tests with the speed and low cost of antigen tests,” said Peter Nguyen, a research scientist at Harvard University’s Wyss Institute.
The sensors could also be embedded into normal clothes such as laboratory coats, potentially offering a novel way to monitor health care workers’ exposure to various types of infections.
“In addition to face masks, our programmable biosensors can be integrated into other garments to provide on-the-go detection of dangerous substances including viruses, bacteria, toxins and chemical agents,” added Mr Nguyen.
The sensors work on a scientific mechanism that the research team had previously developed for use in paper diagnostics for viruses such as Ebola and Zika. The entire project was carried out under quarantine or strict social distancing, starting from May last year.
“It was definitely different from the usual lab infrastructure we are used to working under, but everything we did has helped us ensure that the sensors would work in real-world pandemic conditions,” said Luis Soenksen, a post-doctoral fellow at the Wyss Institute.

Subj: Accelerating in the Middle East
Five years ago, Uber launched in the Middle East. It was the start of an incredible journey, with millions of riders and drivers finding new ways to move and work in a dynamic region that’s become so important to Uber. Now Pakistan is one of our fastest-growing markets in the world, women are driving with Uber across Saudi Arabia, and we chose Cairo to launch our first Uber Bus product late last year.
Today we are taking the next step in this journey—well, it’s more like a leap, and a big one: in a few minutes, we’ll announce that we’ve agreed to acquire Careem. Importantly, we intend to operate Careem independently, under the leadership of co-founder and current CEO Mudassir Sheikha. I’ve gotten to know both co-founders, Mudassir and Magnus Olsson, and what they have built is truly extraordinary. They are first-class entrepreneurs who share our platform vision and, like us, have launched a wide range of products—from digital payments to food delivery—to serve consumers.
I expect many of you will ask how we arrived at this structure, meaning allowing Careem to maintain an independent brand and operate separately. After careful consideration, we decided that this framework has the advantage of letting us build new products and try new ideas across not one, but two, strong brands, with strong operators within each. Over time, by integrating parts of our networks, we can operate more efficiently, achieve even lower wait times, expand new products like high-capacity vehicles and payments, and quicken the already remarkable pace of innovation in the region.
This acquisition is subject to regulatory approval in various countries, which we don’t expect before Q1 2020. Until then, nothing changes. And since both companies will continue to largely operate separately after the acquisition, very little will change in either teams’ day-to-day operations post-close. Today’s news is a testament to the incredible business our team has worked so hard to build.
It’s a great day for the Middle East, for the region’s thriving tech sector, for Careem, and for Uber.
Uber on,
Dara
Who was Alfred Nobel?
The Nobel Prize was created by wealthy Swedish chemist and entrepreneur Alfred Nobel.
- In his will he dictated that the bulk of his estate should be used to fund "prizes to those who, during the preceding year, have conferred the greatest benefit to humankind".
- Nobel is best known as the inventor of dynamite, but also wrote poetry and drama and could speak Russian, French, English and German by the age of 17. The five original prize categories reflect the interests closest to his heart.
- Nobel died in 1896 but it took until 1901, following a legal battle over his will, before the first prizes were awarded.
