"To bring USP and Althash together will open lots of amazing doors of innovation."
Brazilians use fish to create quick test app for Covid-19. Still in the validation phase, the test works from diagnostic tapes produced with zebrafish antibodies. Researchers from the University of São Paulo (USP) created an application that generates tests for the new coronavirus up to five times cheaper than conventional ones, based on experiments with zebrafish (paulistinha fish). Led by the postdoctoral fellow at the Institute of Biomedical Sciences Ives Charlie da Silva, the project has the participation of a multidisciplinary team formed by scientists from several colleges at USP and other educational institutions.
Still in the validation phase, the proposal involves diagnostic tapes equipped with QR codes . The tapes carry antibodies against the coronavirus extracted from eggs of São Paulo fish. The idea is that the patient uses a swab, a kind of cotton swab, to collect their own saliva and, subsequently, apply the sample to the surface to react with the antibodies. "To obtain the result, she [the person] would open the application and read the QR code of the tape," said Ives Charles, in an interview with Jornal da USP.
