Colorimetry: Bifunctional Nano Lycurgus Cup Array Plasmonic Sensor for Colorimetric Sensing and Surface‐Enhanced Raman Spectroscopy (Advanced Optical Materials 10/2015). Issue 10 (20th October 2015) - Chang, Te‐Wei
Abstract 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 × 107, which is the highest among all reported EOT‐based SERS devices, with potential in point‐of‐care (POC) applications.
