“…Up to now, graphene has been combined with a variety of fiber-optic sensing structures for polar gas sensing. [136][137][138] For example, in 2017, Feng et al coated graphene on the surface of tapered PCF for the detection of hydrogen sulfide gas; [139] Khalaf et al coated graphene/polyaniline nanocomposite on the upper surface of side-polished optical fiber for NH 3 detection. [140] However, due to the limitation of interaction efficiency of graphene and light, the sensitivity of the above gas sensors was low.…”

Optofluidic, as an emerging technology that combines photons and microfluidics, has become a powerful, intelligent, and universal sensing platform in the field of bio-chemical sensing. Optical fiber optofluidic (OFOF), as a branch of optofluidic technology, has stimulated a host of remarkable achievements in the field of bio-chemical sensing due to its superiority of compact structure, immunity to electromagnetic interference, low sample consumption, high sensitivity, and real-time dynamic response. In this paper, an overview of OFOF bio-chemical sensors is presented. The OFOF system architectures are introduced and some advanced functional materials and coating technologies that can be utilized in the OFOF sensing platform to achieve high-performance biochemical sensing are summarized. Research progress and current status of OFOF bio-chemical sensors based on various sensing mechanisms are summarized and analyzed, with emphases on their sensing principles, sensing structures, sensing applications, advantages, and disadvantages. Lastly, the existing challenges and future development trends of OFOF biochemical sensors are briefly discussed.

“…The H 2 S reacts with ZnO to form a zinc sulphide layer that covers the surface of the sensor, which effectively increases the refractive index of the medium on top of the ZnO coating. Another material used to detect H 2 S is a graphene oxide coating that produces a redox reaction [155]; other strategies can be found elsewhere [156].…”

At the present time, there are major concerns regarding global warming and the possible catastrophic influence of greenhouse gases on climate change has spurred the research community to investigate and develop new gas-sensing methods and devices for remote and continuous sensing. Furthermore, there are a myriad of workplaces, such as petrochemical and pharmacological industries, where reliable remote gas tests are needed so that operatives have a safe working environment. The authors have concentrated their efforts on optical fibre sensing of gases, as we became aware of their increasing range of applications. Optical fibre gas sensors are capable of remote sensing, working in various environments, and have the potential to outperform conventional metal oxide semiconductor (MOS) gas sensors. Researchers are studying a number of configurations and mechanisms to detect specific gases and ways to enhance their performances. Evidence is growing that optical fibre gas sensors are superior in a number of ways, and are likely to replace MOS gas sensors in some application areas. All sensors use a transducer to produce chemical selectivity by means of an overlay coating material that yields a binding reaction. A number of different structural designs have been, and are, under investigation. Examples include tilted Bragg gratings and long period gratings embedded in optical fibres, as well as surface plasmon resonance and intra-cavity absorption. The authors believe that a review of optical fibre gas sensing is now timely and appropriate, as it will assist current researchers and encourage research into new photonic methods and techniques.

“…Based on the same method of interferometric wavelength drift monitoring, some novel structures have been proposed. For instance, Feng et al [58] reported a H 2 S sensor based on the graphene-coated tapered PCF-MZI, which was capable of detecting hydrogen sulfide gas from 0 ppm to 45 ppm with a response time of 60 s and showed a sensitivity of 0.031 43 nm/ppm, as illustrated in Fig. 4(b).…”
