Blue-ray DVD as a low-cost substrate for the fast sensing of paracetamol in aqueous medium using surface-enhanced Raman spectroscopy (SERS)

Abstract

Surface-Enhanced Raman Scattering (SERS) is an analytical tool for rapid sensing of analytes. We here report the working of a highly sensitive and reproducible SERS substrate by effective guidance of localized plasmon resonance (LSPR) field of silver nanoparticles (AgNPs) trapped in the nano channels of Blue-ray DVD (BR-DVD). The trapped AgNPs in the channels of BR-DVD generate Guided mode resonance (GMR) field. The designed substrate is used for the trace sensing of paracetamol in aqueous medium. The minimum concentration detected is 0.1 mM.
