Bifunctional Nano Lycurgus Cup Array Plasmonic Sensor for Colorimetric Sensing a

A bifunctional ultrasensitive nanoplasmonic sensor is demonstrated with combined surface plasmon resonance (SPR) and surface-enhanced Raman spectroscopy (SERS) sensing capabilities. Unlike traditional extraordinary transmission (EOT) devices, nano Lycurgus cup array (nanoLCA) contains a hybrid confi
