Plasmonic metasurface-enhanced Raman spectroscopy for label-free discrimination of human and murine noroviruses

Noroviruses are a leading cause of acute gastroenteritis worldwide, and their rapid and reliable detection remains a significant challenge for current diagnostic technologies. In this work, we present a plasmonic metasurface platform based on Y-shaped nanocavity arrays designed for label-free viral...
