Scientists have developed a mask that can detect the corona virus in minutes. By detecting the virus in the air, the mask notifies the wearer through an app on their phone. According to experts, this mask also has the ability to diagnose swine flu and bird flu. These diseases are spread in the air in the form of droplets released due to the speaking, coughing or sneezing of infected people. These fine and invisible molecules stay in the air for a long time and people get sick due to breathing in this air.
Researchers in China tested the mask in a closed chamber where a liquid containing virus proteins was sprayed onto the mask. The sensor alerted the wire when only 0.3 microliters of the liquid was sprayed. This amount is 70 to 560 times less than the droplets produced by sneezing and even fewer droplets produced by coughing or talking. The sensor in the mask contains aptamers. It is a type of synthetic molecule that can target proteins present in pathogens.
The aptamers in the masks scientists tested could diagnose Covid-19, swine flu and bird flu. One of the study’s authors, Dr. Yin Feng, from Shanghai Tongji University, says that previous studies have shown that face masks reduce the chance of spreading the disease. He said that we wanted to make a mask that warns of the presence of the virus in the air and warns the wearer of the mask.
