US: Scientists may be able to test food safety with a smartphone
Food and Wine: To test whether food contains the harmful bacteria E. coli, scientists place samples of the questionable sustenance in culture dishes to see if germ-filled colonies form. They wait for daysâ€”two or three, to be exactâ€”to know whether the food is safe to eat, or whether it should be pulled from shelves. But new technology could speed up the food-safety testing process to mere moments, according to research from MIT.
Researchers at the institute have developed a liquid droplet that when dispensed on food binds with any bacterial proteins that might be presentâ€”and that bond can be seen with a trained, naked eye or a smartphone app…
