Researchers Abdur Rehman Anwar, Maruša Mur, Matjaž Humar from Condensed Physics Department of the Jožef Stefan Institute and coworkers from Aristotle University of Thessaloniki, Greece, have developed microlasers made entirely out of edible materials. The microlasers that can be embedded directly inside edible products, were designed as barcodes, or as sensors/indicators for various food-related parameters. Illuminating a food product, containing such microlaser(s), with a laser pulse, and measuring the emission spectrum enables remote measuring of pH, sugar concentration, etc. or reading encoded information e.g., on expiry dates and the food origin. The microlasers are entirely safe for consumption and do not alter the appearance or taste of food. The research on edible microlasers that could significantly enhance traceability, security and freshness monitoring of food, was published in Advanced Optical Materials, and had a significant media impact, with many media outlets publishing the story about edible lasers, including Science, Phys.org, Gizmodo and others.
