Abstract

Bifunctionality of nano Lycurgus cup array (nanoLCA) in colorimetric sensing and surface enhanced Raman spectroscopy (SERS) has been proposed and demonstrated. Plasmonic characteristic of nanoLCA has been investigated through 3D-FDTD simulation, which is consistent with the experimental results of transmission and Raman spectrum measurement. The sensitivity of resonance peak wavelength shift was calculated as 383.26 nm/RIU and Raman signal enhancement factor was estimated as 4.01×107 under wet-state detection condition.
