Carbon nanotube-based sensor can detect SARS-CoV-2 proteins: The technology could be developed as a rapid diagnostic for COVID-19 or other emerging pathogens

Using specialized carbon nanotubes, engineers designed a sensor that can detect SARS-CoV-2 without any antibody, giving a result within minutes. With further development, this kind of sensor could enable rapid and accurate screening for COVID-19 or pathogens that emerge in the future.
