Edible sensors made of glowing droplets could improve food and drug monitoring



Summary

Researchers have developed edible sensors made from glowing, biocompatible liquid droplets. These sensors, which can be consumed and excreted, could revolutionize food and drug monitoring. They utilize bioluminescence, emitting light in response to specific stimuli like changes in pH, temperature, or the presence of certain compounds. This allows for real-time tracking of conditions within the digestive tract or food packaging. Potential applications include monitoring food freshness, detecting spoilage, and ensuring proper drug absorption. The sensors are designed to be safe for consumption and offer a non-invasive way to gather crucial data from within the body or the food supply chain.
