Scientists at Materials Research Department of GSI Helmholtzzentrum für Schwerionenforschung (Helmholtz Center for Heavy Ion Research), working together with colleagues from Argentina and the US, have come up with a sensor that can detect SARS-Cov-2 and other virus within two hours from saliva, serum and wastewater samples.
Not only is the test, co-developed Argentina’s National Scientific and Technical Research Council (CONICET) and the University of Illinois, fast and accurate. Unlike the PCR tests now in use, it’s also capable of distinguishing whether a sample is infectious or whether a person is contagious.
The key to the new test is nanopore technology, which involves thin polymer films being irradiated with high-energy heavy ion projectiles.
“Our vision is to integrate the functionalized nanopore membrane into a portable device for rapid and efficient virus detection and diagnosis,” said Christina Trautmann, head of the GSI Materials Research Department, in a statement.
