New sensor can quickly and cost-effectively detect deadly E.coli bacteria
Scientists have built a new sensor that can detect the potentially deadly E.coli bacteria in 15-20 minutes, much faster than traditional lab tests.E.coli can be transmitted in contaminated food and water, posing particular risks to children and the elderly.In the late spring of 2011 a serious outbreak of E.coli bacteria sickened thousands of people in Germany and killed more than 50.

"Using currently available technologies, which are mostly based on amplification of the sample, it takes several hours to days to detect the presence of bacteria.A fast and accurate detection alternative is, therefore, preferable over the existing technology," said Saurabh Mani Tripathi, a physicist at the Indian Institute of Technology Kanpur.The Indian team worked with researchers from the University of Quebec in Outaouais to combine two techniques to make a practical sensor.

A new sensor has been developed that that detects E.coli bacteria in mere 15 to 20 minutes, much faster than traditional lab tests.A team of researchers from the Photonics Research Center at the University of Quebec in Outaouais, Canada along with the Indian Institute of Technology Kanpur have developed the new sensor that is not only more effective, but also cost-effective.E.coli can be transmitted in contaminated food and water, pose risks to children and elderly.
