American biologists have learned to determine the strain of coronavirus by saliva

American biologists have developed a new diagnostic platform miSHERLOCK, which allows you to identify different strains of coronavirus from saliva. The results of the study are published in the journal Science Advances.

The new test is based on the CRISPR genetic editing technology. According to scientists, the system is now able to detect British, South African, and Brazilian strains of SARS-CoV-2. At the same time, the platform can be easily programmed to detect new variations of COVID-19. The accuracy of the results is 95 percent.

To use miSHERLOCK, the user needs a set of reagents, a smartphone with a camera and an application, as well as a battery and a plastic incubator. The test result can be obtained in one hour. According to the developers, this portable system is so simple that it can be used at home, and the cost of the platform is about $15.

Earlier, scientists from the University of Melbourne (Australia) found a way to stop the reproduction of the coronavirus. To successfully block SARS-CoV-2 in infected human cells, they used the CRISPR gene-editing technology.
