“…They discussed the effect of polishing depth and sensing area length on the performance of the biosensor [31]. The conclusions from this study reveals that the higher polishing depth provides the narrower curves for normalized transmitted power, and smaller sensing area lengths leads to better quality parameters, regardless of the number of graphene layers [31].…”

“…In these geometries, the cladding section of fiber will be polished (via, for example, the wheel polishing technique [29]), and then plasmonic nanofilms or nanoparticles will be deposited on the flat surface of fiber (via, for example, the vacuum evaporating method [29]), as illustrated in Figure 6. The interaction between fiber and plasmonic modes can form a transmission dip (absorption peak) in light transmission spectra, depending on the biological sample refractive index (RI) on the surface of nanofilms/nanoparticles [29][30][31]. This mechanism can be used to detect an unknown molecule or monitor the variations in analyte RI.…”

Plasmonic fiber-optic biosensors combine the flexibility and compactness of optical fibers and high sensitivity of nanomaterials to their surrounding medium, to detect biological species such as cells, proteins, and DNA. Due to their small size, accuracy, low cost, and possibility of remote and distributed sensing, plasmonic fiber-optic biosensors are promising alternatives to traditional methods for biomolecule detection, and can result in significant advances in clinical diagnostics, drug discovery, food process control, disease, and environmental monitoring. In this review article, we overview the key plasmonic fiber-optic biosensing design concepts, including geometries based on conventional optical fibers like unclad, side-polished, tapered, and U-shaped fiber designs, and geometries based on specialty optical fibers, such as photonic crystal fibers and tilted fiber Bragg gratings. The review will be of benefit to both engineers in the field of optical fiber technology and scientists in the fields of biosensing.

Resonance optical fiber sensors are widely studied for their high sensitivity, small size, and anti-electromagnetic interference. However, traditional resonance optical fiber sensors have encountered bottlenecks in the trace detection due to limited localized field intensity and low molecules affinity. With the development of materials technology, low-dimensional materials such as quantum dots, graphene, and transition metal sulfides have excellent properties such as high carrier mobility, large specific surface area, and flexible structure controllable artificial technologies that can also be used to synthesize new materials with desired characteristics, which can enhance the performance of sensors fundamentally. The introduction of low-dimensional materials can not only achieve the performance optimization of sensors, but also make sensors functional to realize the diversification of detection objects. This paper reviews the research progress of resonance optical fiber sensors based on low-dimensional materials. The detection principle and performance indexes related to resonance optical fiber sensing are elaborated, and resonance optical fiber sensors modified by low-dimensional materials are introduced. Furthermore, the role of low-dimensional materials in resonance fiber sensing is summarized, the direction of performance optimization in the production process of resonance fiber sensors is analyzed, and the future prospect of new resonance optical fiber sensors is given.
