“…Several efforts have been reported to develop biosensors for the rapid diagnosis of HFMD, without thorough investigation of their performance. Udos et al reported the development of a biosensor for the detection of Enterovirus A71 in synthetic analytes [54] . The fabrication and functionalization of the sensor was optimized, with a noted focus on eliminating false detection which may be caused by refractive-index noise.…”

“…The biosensor was tested by measuring the optical spectrum and quantifying the viral concentration. It was noted that the sensor could detect a concentration of 0.343 ng/mL in 4 min, with a marked selectivity towards EV-A71 in the presence of other HFMD-causative viruses [54] . In addition, Liu et al developed a biosensor for the detection of Singapore grouper iridovirus (SGIV), which is a dangerous form of iridoviruses [53] .…”

“…A core-shift welding technology has been investigated in [15], where a light is directly injected into the sensing fiber cladding to obtain the evanescent field at the interface between the cladding and the air. Several types of optical fiber grating-based SPR sensors have also been proposed such as in [16]- [18]. Recently, many two-dimensional materials have been discovered to enhance the optical fiber SPR sensors performance.…”

A few-mode optical fiber surface plasmon resonance sensor with graphene layer is investigated, firstly, with the aim of studying the behavior of the guided modes and, secondly, with the aim of determining the range of the measured refractive index for some selected few-mode fibers. The results show that as the number of modes propagated in the fiber increases, the maximum sensitivity of a particular mode decreases while the range of the measured refractive index of that mode increases. Also, it is shown that the range can be easily tuned with sensitivity consideration by only adjusting the operating wavelength without any modification of the sensor, which is desirable from practical point of view. In addition, it is shown that the core diameter of the fiber should be chosen according to sensitivity and range needing, where a compromise between them must be found. The study presented in this paper can significantly help in developing new sensing techniques, such as multi-parameter sensing, by monitoring the various responses of the modes. Also, it can be used to customize the sensor for specific sensing applications in various fields, especially to measure refractive indices in subranges of 1.38 to 1.46.

“…To provide proper sensitivity, the outer cladding diameter of the fiber must be modified, which requires additional technological treatment. Udos et al demonstrated a biosensor based on the surface plasmon resonance tilted fiber Bragg grating (SPR-TFBG) for the detection of the refractive index in order to detect enterovirus A71 [23]. In this case, it is required to cover the TFBG optical fiber with a layer of gold to obtain an SPR effect.…”

This article proposes a new method for detecting slight refractive index changes under conditions of unknown polarization state. It is argued that an insignificant modification of the tilted fiber Bragg grating (TFBG) structure and selecting the appropriate spectral region allows us to accurately track changes in the refractive index. It has also been proven that the method can be easily made insensitive to temperature and that the sensitivity to changes in the polarization plane of the input light can be significantly reduced, which is crucial in later practical applications. Analytes in the form of an aqueous glucose solution were used to calibrate the sensor. The proposed method, based on perpendicular tilted fiber Bragg grating (P-TFBG), has a wide range of universality because its development and slight modification will enable the detection of glucose, pathogens, and viruses.
