TestNPass to fight COVID-19


The COVID-19 pandemic revealed the urgent need for inexpensive, easy-to-use, and reliable diagnostic tools for rapid on-site screening.

TestNPAss diagnostic test requires a simple saliva sample to detect SARS-CoV-2 infection rapidly. It is a single-use test using a graphene biosensor sensitized by antibodies recognizing the virus's S protein. The test operates without a battery and uses contactless near-field communication via a smartphone application.


In 5 minutes, the digital test detects viruses' presence without the need for dedicated reading equipment other than a smartphone. The signal is captured electronically on the biosensor, which accelerates the diagnosis and allows a secure digital transfer of the result.

The test result is tamperproof and recorded in an RFID tag securing user confidentiality and constituting a standalone digital health pass that does not require data transfer over a network.
