Nano sensor slashes pathogen detection time, inventors claim
Monday 11 December 2006A handheld sensor under development uses nanoparticles to detect foodborne bacteria in 15 minutes, its inventors claim.
Scientist Su Dwarkanath and her husband Sri Satyanarayana, and engineer, are targeting the new sensor at a tool for the quick dectection of e-coli and other pathogens in foods. It can normal testing can take up to 24 hours they claim.
The device offers a way to speed up detection, allowing processors to release products for distribution earlier and to spot contamination problems before goods leave the plant.
