Feb. 8, 2022 (EIRNS)—Scientists at Fudan University in Shanghai have come up with a new method for coronavirus testing, which they say is as sensitive but much quicker than PCR lab testing. The new method involves electromechanical sensors capable of detecting, with high precision, SARS-CoV-2 RNA in human genetic material, according to the study published Monday in Nature Biomedical Engineering science journal.
“We implemented an electromechanical biosensor for the detection of SARS-CoV-2 into an integrated and portable prototype device, and showed that it detected [the virus RNA] in less than four minutes,” the researchers said.
The study involved testing the new method on 33 samples taken from Covid-19-infected patients and 54 Covid-negative controls taken from people with influenza and fever, as well as from perfectly healthy subjects. PCR tests were also taken. The new electromechanical sensor showed results that matched excellently with the PCR tests, showing positive results for those infected with Covid-19 and negative for other samples. The results of the testing were received within four minutes.
