“…The refractive index sensitivity reached 3957 nm/RIU, which is 1.4 times that of the fiber/Ag film sensor. By comparing the experimental results of the two kinds of sensors that were designed, we further illustrate the rationality and feasibility of this study for improving the sensor performance [26][27][28]. Therefore, the sensor proposed in this paper has wide application prospects in bio-detection and industrial production [29].…”

A fiber/Ag-Cu films surface plasmon resonance (SPR) refractive index (RI) sensor composed of multimode fiber-no-core-fiber-multimode fiber (MMF-NCF-MMF) structure is designed. The sensing region length and Cu film deposition time of sensor are gradually optimized by the control variable method, which finally achieves the improvement of sensor properties. We experimentally compared the sensing performance of the fiber/Ag film and fiber/Ag-Cu films sensor. Experimental results show that the fiber/Ag-Cu films sensor has good linearity (R-square = 0.993), and its sensitivity is as high as 3957 nm/RIU in the refractive index detection range of 1.3328–1.3853, which is 1109 nm/RIU higher than the sensitivity of a conventional fiber/Ag film sensor. The sensor presented in this paper adopts the structure with composite metal film, which outperforms the common single-layer metal film in chemical stability such as oxidation resistance and mechanical hardness. Meanwhile, the SPR sensor with MMF-NCF-MMF structure has the advantages of convenient manufacture and compact structure. In conclusion, it can bestow a unique advantage in the field of biological detection or chemical analysis.

“…We compare the IgG sensing sensitivity and anti-environmental interference capability of the proposed HIPFG immunosensor to other reported optical fiber sensors in Table 2 . Although previous reports on IgG sensors are superior in LOD for IgG detection, most of them lack evaluation for environmental factors [ 40 , 41 ], and some of them are sensitive to those factors, which limits their application in mobile equipment and compact devices [ 24 ]. As listed in Table 2 , the sensitivities for torsion, strain, and temperature of HIPFG are significantly smaller than the corresponding values of the previously reported optical fiber IgG sensor, providing stable and reliable sensing performance for IgG sensing.…”

All Fiber-Optic Immunosensors Based on Elliptical Core Helical Intermediate-Period Fiber Grating with Low-Sensitivity to Environmental Disturbances

et al. 2022

An all fiber-optic immunosensor based on elliptical core helical intermediate-period fiber grating (E-HIPFG) is proposed for the specific detection of human immunoglobulin G (human IgG). E-HIPFGs are all-fiber transducers that do not include any additional coating materials or fiber architectures, simplifying the fabrication process and promising the stability of the E-HIPFG biosensor. For human IgG recognition, the surface of an E-HIPFG is functionalized by goat anti-human IgG. The functionalized E-HIPFG is tested by human IgG solutions with a concentration range of 10–100 μg/mL and shows a high sensitivity of 0.018 nm/(μg/mL) and a limit of detection (LOD) of 4.7 μg/mL. Notably, the functionalized E-HIPFG biosensor is found to be insensitive to environmental disturbances, with a temperature sensitivity of 2.6 pm/°C, a strain sensitivity of 1.2 pm/με, and a torsion sensitivity of −23.566 nm/(rad/mm). The results demonstrate the considerable properties of the immunosensor, with high resistance to environmental perturbations, indicating significant potential for applications in mobile biosensors and compact devices.

“…Graphene-on-gold SPR imaging platform with a ca. 40% sensitivity enhancement was demonstrated experimentally 10 and highly sensitive GEMSPR sensors were used for biological sensing, [11][12][13][14][15] even gas sensing. 16,17 Although GEMSPR sensors can greatly enhance the performance in term of sensitivity comparing with the conventional SPR sensors, their intrinsic refractive index sensing character are still reserved.…”
