IT House News on February 10, according to the People's Daily, the nucleic acid detection of the new crown virus is mainly used in the "polymerase chain reaction" (PCR) technology, and the detection time often takes 2 to 24 hours. The research team of Fudan University has developed a new type of crown detection equipment and method, which can produce nucleic acid detection results within 5 minutes, which is better than the existing new crown nucleic acid PCR detection method.
IT House learned that the research team developed a super-sensitive biosensor based on a microelectromechanical system and integrated this sensor into a portable device. Analysis of genetic material in swabs by microelectronics can detect viral RNA in 0.1 to 4 minutes. This new method is fast, sensitive and simple to operate, not only has no false negative results, but also is much faster than the speed of traditional nucleic acid detection.
In addition, the researchers found that the current common "polymerase chain reaction" (PCR) detection method is not effective at extremely low virus concentrations, while the ultra-sensitive biosensors of this microelectromechanical system can still detect the virus.
The researchers say that in the future, the new device is easy to carry and can be adapted to a variety of occasions and situations, including airports, clinics, and even at home.
