MIT, Harvard University Develop Face Masks With Biosensors Capable Of Covid-19 In Just 90 Minutes

Covid has forced people to wear masks and it has now become a very essential thing when it comes to staying safe from highly infectious diseases. But the way we have been using masks is set to change as researchers have developed a technique that helps it detect cases of Covid-19 in just 90 minutes. These masks are equipped with biosensors and can detect Covid in the breath of the wearer. The technology has been jointly developed by the Massachusetts Institute of Technology and Wyss Institute at Harvard University. The biosensors developed by researchers can be integrated into the fabric and is capable of detecting pathogens.

When integrated with standard KN95 face masks, these biosensors successfully detected the presence of coronavirus in a person’s breath. The study published in Nature Biotechnology this week states that the biosensors can be activated with the help of buttons attached to masks. Once activated, the sensors can give results in just 90 minutes. Researchers claimed that the level of accuracy of these biosensors is as good as the result of standard PCR tests. A PCR Covid test detects the presence of SARS-CoV-2 virus using the technique of polymerase chain reaction. The biosensors are capable of detecting other bacteria, toxins, and chemical agents.

Researchers have used the technique of freeze-drying the molecular machinery. When the wearer presses the button, a small amount of water is released into the sensor. This reactivates the freeze-dried components which can signal the presence of coronavirus. Once activated, the sensor sends a signal to mobile about exposure to the virus. Scientist Nina Donghia said that the technology can be inserted in the lab coats of frontline workers. This will help them detect whether they are exposed to the virus. As a result, the lives of several people who are often exposed to the virus can be saved. Researchers are now looking to partner with manufacturers so that these masks can be made easily accessible to the common man.
