The tabletop diagnostic yields results in an hour and can be programmed to detect variants of the SARS-CoV-2 virus. Researchers report that the diagnostic is just as accurate as PCR tests.

Engineers at MIT and Harvard University showed that the device can also be used to detect specific viral mutations linked to some of the SARS-CoV-2 variants that are now circulating. This result can also be obtained within an hour, potentially making it much easier to track different variants of the virus, especially in regions that don’t have access to genetic sequencing facilities.

“We demonstrated that our platform can be ...
