Ultrasensitive detection of amlodipine using plasmonic optical fiber sensors enhanced with graphene oxide and chitosan nanocomposite

Abstract In this study, we introduce an innovative reflective fiber optic sensor platform for detecting amlodipine (AML) concentrations based on surface plasmon resonance (SPR). The sensor architecture features a reflective fiber coated with a thin layer of gold to induce SPR, while a graphene oxide...
