GRAPHENE BIOSENSORS FOR COVID-19 FIELD TESTS
In response to the current sanitary crisis, Grapheal is developing a diagnostic test based on saliva sampling for the rapid screening of Covid 19 infection This all-electronic test is an antigen immunoassay: it the presence of the virus itself and not the immune response commonly found in current generation rapid tests. It allows the result to be electronic captured at the heart of the device which speeds up the diagnosis and allows secure digital transfer of the result.
Principle of operation
When sensitized with appropriate anti bodies, which target the proteins at the surface of SARS-Cov-2 virus, graphene sees its electrical conductance affected by the presence of the virus : it can detect the virus in body fluids, thus providing highly efficient diagnostic tests.
