Abstract

original image

A lithographically encoded microtaggant for the anti-counterfeiting of drugs is presented by Wook Park, Sunghoon Kwon, and co-workers on page 5924. The microtaggant utilizes the high-capacity and error-correctable features of Quick Response (QR) code to store large amounts of drug information. The image illustrates the incorporation of QR-coded microtaggants in a capsule as a demonstration of on-dose authentication (ODA). Try reading the code with your smartphone!
