“…The wide analyte sensing range includes any liquid analyte having a refractive index range of 1.14-1.36 RI. References [12], [34]- [36] illustrate sensor works targeted for low analyte RI detections. However, with our non-linear rise of wavelength sensitivity, the sensing readings are much higher in a broader sensing range of analytes.…”

“…To excite SPR, there are few nanomaterials placed on a dielectric substrate to achieve the interaction of light and free electrons, such as gold and silver. Up to now, several SPR devices have been proposed including prism-coupled microfluidic systems [6][7][8][9][10], metal-coated fiber-optic sensors [11][12][13], gold-integrated MOF sensors [14,15], graphene-based plasmonic chip [16], and antimonene-based sensor [17], etc. These SPR-based devices possess the advantages of high performance, which makes them a promising tool for the optical detection.…”

A surface plasmon resonance (SPR) based microstructured optical fiber (MOF) is designed and theoretically investigated for dual-channel optofluidic sensing. The design of the MOF consists of a solid silica core surrounded with double air holes, and the hollow section is coated with thin Ag film to excite the surface plasmon waves on the dielectric interface. The optofluidic sensing characteristics of the individual channel have been analyzed based on mode-coupling theory between core and plasma modes. By filling the dual channel with different liquid analyte, the resonance wavelengths are adjusted away from each other to achieve dual-optofluidic-channel sensing. When the refractive index (RI) of liquid samples varies from 1.33 to 1.39 RIU, the optofluidic sensing sensitivities of channel 1 and channel 2 in MOF are 1439.29 nm/RIU and 4003.57 nm/RIU, respectively. The proposed SPR-based MOF is appropriate for multi-channel biological and chemical sensing fields.
