Chao Zhang, Ph.D. and his team of researchers in Beijing have created a smart tag that will tell you whether or not the contents of your packaged food has spoiled. The tiny tag would be placed on the packaging and could also be used for medicine. The tags were presented at the National Meeting and Exposition of the American Chemical Society.
Chao Zhang, the lead researcher on the project, explained that the small, jelly-like tags change color based on freshness. Red is fresh, orange is half fresh, yellow is almost spoiled and green is spoiled. The tags are made out of silver and gold nanorods.
It’s never fun when you accidentally drink sour milk and now you’ll be able to avoid that thanks to these helpful smart tags.
