IdentifySensors Biologics' electronic nanosensors instantly identify COVID in saliva
6 January 2022 -

Nanotechnology firm IdentifySensors Biologics revealed on Wednesday that electronic nanosensors, Check4 reader and COVID testing cartage, instantly identify COVID in saliva with greater than 95% accuracy based on its proof-of- concept testing at Purdue University.

The company has patented the electronic nanosensors and is moving into large-scale manufacturing in the Q2 2022. This paves the way for an all-new approach in high-quality rapid COVID testing without the error rates associated with at-home rapid antigen tests. The businesses, governments and organizations can remotely monitor individual test results in real time for employees, customers and visitors.

According to the company, the Check4 reader and COVID testing cartage can instantly detect pathogens electronically from saliva with the accuracy of a PCR test. The portable test can be used anywhere, anytime and connects wirelessly to a user's smartphone and the cloud.

To take the test, the users place a small saliva sample into a test cartridge about the size of a business card. The cartridge slides onto a reusable handheld reader device. Sensors inside the test cartridge fire electrical signals through the saliva and proprietary algorithms measure the current to determine the presence of the virus. The Check4 device requires no amplification or lab work, said the company.

Each single-use test cartridge is expected to cost less than USD60. The reusable reader is expected to cost about USD129. The reusable reader can be used for up to 20,000 tests. The company is seeking FDA approval and is also accepting purchase orders.
