TestNPass is Grapheal’s diagnostic test based on saliva sampling that can be used to rapidly screen for the COVID-19 infection. Within 5 minutes, the digital test detects the presence of the virus without the requirement of dedicated reading equipment other than a smartphone or a standard NFC-connected device. When the SARS-CoV-2 virus binds to antibodies contained in TestNPass, a specific electrical signal is detected. This signal can be captured electronically on the device, which speeds up the diagnosis and allows the result’s secure digital transfer.

WoundLAB is a flexible and transparent graphene-based biosensor patch that continuously records and stores wound biochemical parameters. A smartphone app is then used to communicate this data to a telemedicine cloud for data aggregation and further analysis. This allows caregivers to monitor wound healing in their patients remotely, with prompt alerts if any infections or medical complications arise.
