In the News--Food Safety and a Smartphone App?

A new technology being developed at the University of Illinois, Urbana-Champaign, may help us identifyfood safety issues.  If I read this correctly, the researchers are building a smartphone cradle and app which would turn a smartphone into a biosensor.  If this technology works as planned, we can use our smartphone (with the cradle and app) to detect toxins, bacteria, identify allergens in foods, and check for water contamination.  This information can be found at http://www.foxnews.com/health/2013/08/01/smartphone-cradle-and-app-detect-toxins-bacteria-for-people-with-allergies/
