COVID-19 Molecular Gene Test Uses Nanosensor Technology to Detect Early and Asymptomatic Infections

A molecular gene test based on innovative nanosensor technology could reshape the future of COVID-19 diagnostic testing.

IdentifySensors Biologics (Shaker Heights, OH, USA), along with researchers at Purdue University (West Lafayette, IN, USA), has developed the new digital technology that aims to replace 50-year PCR testing for multiple infections, including COVID variants. It has finalized proof-of-concept research for its all-new COVID-19 testing method. IdentifySensors is currently in the commercialization stage with Check4, its testing platform that comprises two parts - a re-useable reader and cartridges that intend to check for several infections and pathogens. The first cartridges are intended to test for COVID and the multiple variants, and then a multiplex cartridge which will test for COVID and influenza A and B.

Check4 intends to be a highly accurate, over-the-counter self-test that is fast, accurate, and affordable. It detects early and asymptomatic infections with the accuracy of a PCR test, but without all the necessary reagents, machines, people, and delays. It is intended to avoid the limitations of current molecular tests such as enzymatic reactions, amplification, sample preservation or sample transportation, which can introduce artifacts and raise the risk of false positives. It is not an inaccurate antigen test. This electronic-based disruptive technology intends to use newly-developed nanosensors, saliva, and a user’s smartphone to disrupt the way testing is done now, and into the future. Using saliva and the user’s smartphone, results will be delivered within minutes. Check4 is easy to use and fast, accurate, and affordable. Future intended tests include MRSA, Lyme, Hep C and B, foodborne pathogens, and more.

“With COVID still raging around the globe, our test is a game-changer,” said Dr. Gregory Hummer, founder of IdentifySensors Biologics. “It’s fast, affordable and intends to provide accurate results withing minutes on your smartphone. Check4 can help us get back to living a more normal life.”
