New COVID-19 Sensor May Improve Mass Testing

June 6, 2022
Researchers at Johns Hopkins University develop fast and accurate COVID-19 technology.

A new COVID-19 sensor developed by researchers at Johns Hopkins University with support from the National Science Foundation (NSF) may make current limitations to the two most widely used types of testing a thing of the past, according to an article from the NSF. At present, PCR tests require sample preparation and wait times, while rapid antigen tests are less accurate.

Ishan Barman, one of the senior authors of the study, notes the new technique is as simple as putting a drop of saliva on the sensor device and quickly obtaining a positive or negative result. The simple-to-use sensor technology reportedly is almost as sensitive as PCR testing and as convenient as a rapid antigen test. According to the NSF, the device, which isn’t yet available, doesn’t require sample preparation and can be delivered as a disposable chip.
