A Carbon Nanotube Sensor for COVID
January 4, 2022 | Terry Sharrer
“Scientists at MIT announced the development of a rapid COVID-19 test that can detect the virus in a saliva sample in as little as five minutes. The technology does not require antibodies or other expensive reagents typically associated with protein detection, and is instead based on carbon nanotubes. The nano-structures are encased in a web of polymers, into which the target molecules stick, altering the fluorescent signal generated when the nanotubes are illuminated using a laser. The researchers were able to rapidly adapt the nanotube technology to detect SARS-CoV-2, suggesting that it could be useful in future pandemics involving yet unknown pathogens.” MORE
