Safe, Ingestible Fluorescent Silk Tags Authenticate Medications
WEST LAFAYETTE, Ind., April 22, 2022 — To help block the flow of counterfeit medications, researchers at Purdue University and the National Institute of Agricultural Sciences in South Korea developed edible fluorescent tags that can be coded and added to pills or liquid medicine. Each tag is made from photoluminescent natural biopolymers and contains an imperceptible matrix code of information about the pharmaceutical. The code can be read with a smartphone app. The timeliness of the development stems from supply chain issues
