20.500.12556/RUL-176712 Microlasers made entirely from edible substances Biolasers composed of biological and biocompatible materials are increasingly used in biomedical applications, including cell barcoding and biosensing. However, no studies have focused on creating lasers from edible substances. Here, consumable substances for both the laser cavity and the gain material are systematically explored. Several fluorescent dyes are identified as effective gain materials for lasing. Two types of microcavities are demonstrated: whispering gallery mode and Fabry–Pérot. The edible microlasers are employed as sensors and barcodes. Due to their extremely narrow spectral lines, the microlasers provide exceptional sensitivity to various environmental factors. They are designed to sense sugar concentration, pH, the growth of bacteria, and exposure to too-high temperatures. Additionally, they encode multiple data bits, such as manufacturer information and expiration dates, while also functioning as physical unclonable functions for anti-counterfeiting. The microlasers developed in this study are entirely safe for consumption, do not alter the appearance or taste of food, and are environmentally friendly. Unlike traditional barcodes and sensors placed on the packaging, edible lasers can be embedded directly into edible products. They can significantly enhance traceability, security, and freshness monitoring of food and pharmaceuticals as well as non-edible products and can be employed for environmental monitoring and biomedical applications. anti-counterfeiting barcoding edible materials microlasers sensing biolaserji mikrolaserji biomedicina true false true Angleški jezik Slovenski jezik Članek v reviji 2025-12-09 16:39:42 2025-12-09 16:39:47 2025-12-23 04:17:16 0000-00-00 00:00:00 2025 0 0 11 str. iss. 22, art. 2500497 Vol. 13 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 60 2195-1071 10.1002/adom.202500497 240820739 Advanced_Optical_Materials_-_2025_-_Anwar_-_Microlasers_Made_Entirely_from_Edible_Substances.pdf Advanced_Optical_Materials_-_2025_-_Anwar_-_Microlasers_Made_Entirely_from_Edible_Substances.pdf 1 13723CB1FCF8D214D3CEA29B70E5C641 c95d7ef36231bb86fcde1848a5c4a0392a8916bcff1a7db534a2269db786a49d 2897e487-d515-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=223235 https://advanced.onlinelibrary.wiley.com/doi/10.1002/adom.202500497 0 110ef915-d515-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=223234 Fakulteta za matematiko in fiziko 0 0 0
