Paper Abstract

A novel gold nanorods (GNRs) modified optical fiber localized surface plasmon resonance (LSPR) sensor for biochemical detection is demonstrated. The gold nanorods (GNRs) assembled film as the sensing layer was built on the polyelectrolyte (PE) multilayer modified sidewall of an unclad optical fiber. Poly (allylamine hydrochloride) (PAH)/poly (sodium 4-styrenesulfonate) (PSS) films were formed through layer-by-layer (LbL) assembly. The influence of the thickness of polyelectrolyte films was investigated. Simultaneously, the feasibility of the proposed film coupled nanorods optical fiber LSPR sensor in monitoring a series of concentration sucrose solutions with different refractive index is examined. Results suggest that the compact sensor can perform qualitative and quantitative detection in real-time biomolecular sensing.
