Nanomechanical sensor for the accurate, rapid detection of COVID-19

Researchers at Johns Hopkins University (MD, USA) have reported on a nanomechanical sensor that combines the accuracy of the gold-standard PCR tests with the speed of rapid antigen tests for the detection of COVID-19. With the COVID-19 pandemic continuing to place strains on international economies and travel, especially with the emergence of novel variants, the need for rapid yet highly accurate viral detection is urgent. While the most popular method for highly accurate detection remains the standard qRT-PCR test, different techniques and technologies have been examined. These include a graphene-based field-effect transistor sensor, a saline gargle solution in conjunction with...
