Engineering Gap‐Enhanced Raman Tags for High‐Performance Security Inks: A Focus on Raman Tag Density and Stability

open access: yesAdvanced Materials Interfaces, EarlyView.
Gap‐enhanced Raman tags (GERTs) with optimized tag density and stability are engineered for use in high‐performance security inks. The inks enable invisible molecular‐level encoding, long‐term signal retention, and high sensitivity. This work demonstrates a robust, scalable platform for anti‐counterfeiting and authentication with potential integration ...
