Unlike traditional extraordinary transmission (EOT) devices, a nano Lycurgus cup array (nanoLCA) contains a hybrid configuration of a periodic quasi‐3D nanostructure array and dense sidewall metal nanoparticles within each nanostructure, enabling visible colorimetric sensing and SERS chemical identification on the same device. On page 1397, M. R. Gartia, X. Liu, G. L. Liu, and co‐workers calculate the SERS enhancement of nanoLCA for a liquid sample as 2.8 × 10 7 , which is the highest among all reported EOT‐based SERS devices, with potential in point‐of‐care (POC) applications.
