When it comes to the “smell test,” the nose isn't always the best judge of food quality. Now in a study appearing in ACS’ journal Nano Letters, scientists report that they have developed a wireless tagging device that can send signals to smartphones warning consumers and food distributors when meat and other perishables have spoiled. They say this new sensor could improve the detection of rotten food, so it can be tossed before consumers eat it.
