Researchers from the University of Texas at Austin have developed a new sensor that can detect COVID-19 and flu within 10 seconds.
The ultra-thin nanomaterial, made from graphene, can detect viruses at lower levels and more quickly than conventional options like lateral flow devices.
The sensor works by using antibodies linked to graphene, which bind to target proteins and change the electrical current, allowing it to distinguish between the viruses.
The sensor was able to detect viral proteins even at low quantities in samples that resembled saliva during testing. This new technology has the potential to revolutionize virus testing, allowing for faster and more accurate diagnoses of multiple infections.
