A Surface Plasmon Resonance Bio-Sensor Based on Dual Core D-Shaped Photonic Crystal Fibre Embedded With Silver Nanowires for Multisensing

In this paper, for sensing and monitoring the biochemical analyte dissolved in liquid, antigen-antibody interaction or protein-DNA/RNA binding process, we design a surface plasmon resonance refractive index based biosensor by using dual core D-shaped six-fold photonic crystal fibre which is embedded with silver nanowires multi-detection. We numerically analyze both dispersion relations loss spectra various analytes finite element method. This optical bio-sensor monitors changes of different measuring spectral shifts peaks at their wavelengths. With wavelength interrogation method, find that proposed two channels exhibits maximum sensitivity 3400 nm/RIU resolution 2.94 × 10 -5 RIU large range from 1.35 to 1.50, covers most known proteins, viruses DNA/RNA. By utilizing 200 nm channels, can be enhanced up 4000 nm/RIU. Due its special two-channel multi-sensing, it possible distinguish/study possibility/capability unknown target proteins simultaneously. Further, introducing another critical channel, confinement either channel I II greatly high accurate result more reliable sensing. Moreover, prove diameter nano wires has great influences on biosensor.
