What is CNTFET Biosensor for Salmonella Detection about?

This document discusses using a carbon nanotube field effect transistor (CNTFET) as a biosensor for detecting pathogenic bacteria like Salmonella. CNTs are effective transducer materials due to their high surface area and sensitivity to charge. The CNTFET can detect changes in electrical conductivity when bacteria bind to antibodies attached to the CNT surface. In experiments, the CNTFET biosensor was able to detect as few as 100 colony forming units of Salmonella per mL in 1 hour, providing faster results
