Bimetallic nanowire based multianalyte SPR biosensor with Photonic Crystal Fiber

The technique of Surface plasmon resonance (SPR) is used to measure the bimolecular interaction. Due to advantages over prism and optical fiber, Photonic crystal fiber (PCF) based SPR sensing have lot of research interest. In this study, a PCF based SPR sensor having bimetallic nanowires for multianalyte sensing is proposed. Multianalyte sensing is performed using superposition of SPRs with the use of spatially distributed multi metals nanowires. The performance characteristics of SPR peaks are also good.
