Nanoparticles Aid E. Coli Detection
The particles each contain a few molecules of flourescent dye, which reacts with the bacteria to give off a glow. Using this technique, the presence of E. coli can be verified in approximately 20 minutes.
Detecting E. coli rapidly is a critical task, as it can spread quickly, contaminating food and causing illness. Researchers are optimistic that this approach may be used to detect other pathogens.
