このQRコード付きの小さなシルクのタグは、あなたが買おうとしているウイスキーが偽物かどうかを明らかにするセキュリティ対策です。パデュー大学と韓国の国立農学研究所の生物医学エンジニアが開発したこのタグをスマートフォンで読み取るだけで、その飲み物が本物かどうか確認できるのです。
もちろん、現在、ウイスキーのボトルにタグは設置されていない。しかし、ACS Central Science誌に発表されたこの新しい偽造防止技術は、アルコール業界の解決策を見つけるだけでなく、偽薬への対処にもつながる一歩となるかもしれない。

Abstract
Counterfeit medicines are a healthcare security problem, posing not only a direct threat to patient safety and public health but also causing heavy economic losses. Current anticounterfeiting methods are limited due to the toxicity of the constituent materials and the focus of secondary packaging level protections. We introduce an edible, imperceptible, and scalable matrix code of information representation and data storage for pharmaceutical products. This matrix code is digestible as it is composed of silk fibroin genetically encoded with fluorescent proteins produced by ecofriendly, sustainable silkworm farming. Three distinct fluorescence emission colors are incorporated into a multidimensional parameter space with a variable encoding capacity in a format of matrix arrays. This code is smartphone-readable to extract a digitized security key augmented by a deep neural network for overcoming fabrication imperfections and a cryptographic hash function for enhanced security. The biocompatibility, photostability, thermal stability, long-term reliability, and low bit error ratio of the code support the immediate feasibility for dosage-level anticounterfeit measures and authentication features. The edible code affixed to each medicine can serve as serialization, track and trace, and authentication at the dosage level, empowering every patient to play a role in combating illicit pharmaceuticals.
