Scientists developed face mask Which can detect viruses in the air, including coronavirus and flu. The mask is capable of detecting the virus even in very low concentrations in liquid or gas.
It has been promoted as a Early warning system that can help prevent outbreaks of various infectious diseases.
The mask is attached to electronic devices and their signals can be processed in real time, issuing a quick alert if a virus is detected.
“Previous research has shown that Wearing a face mask may reduce the risk of spreading and contracting diseasesaid Yin Feng, a materials scientist at Shanghai Tongji University and corresponding author of the study.
“So we wanted Make a mask that can detect the presence of virus in the air and alert the wearer,
Yin Feng says the mask will work especially well in spaces known to As closed environments of high risk for virus transmission.
How does the mask work?
It can detect common respiratory viruses in the air as droplets or aerosols, which cause widespread flu-like illnesses. COVID-19 or H1N1 (also known as swine flu), when infected people talk, cough or sneeze.
These viruses can remain suspended in the air for some time.
“Our mask will work great in places with poor ventilation, such as elevators or closed rooms, where the risk of infection is highFang said.
team of scientists developed A tiny sensor with aptamers, a type of synthetic molecule that can identify the unique proteins of pathogens as evolved ones do,
They used three types of aptamers, which can recognize surface proteins. SARS-CoV-2, H5N1 and H1N1.
Once the aptamers bind to the target protein, a transistor in the sensor of the mask is activated, Which sends an alert to the mask wearer’s phone within 10 minutes.
