Optical fiber hydrogen (H 2 ) sensors have garnered attention for avoiding explosion hazards in flammable gas environments. Conventional optical fiber sensors rely on electron beam sputtering and chemical coating for functionalization, but these methods may not achieve precise functionalization of intricate structures. Based on 4D printing principles, an H 2 -sensitive ink containing methacrylate groups modified palladium (Pd) nanoparticles (NPs) is reported, with a printing resolution of 200 nm. Then, a fiber-tip clamped-beam H 2 sensor is fabricated with the femtosecond (Fs) laser-induced two-photon polymerization (TPP) technique. The sensor exhibits compact dimensions and fast responses, only 2.64 s for a 4.0 vol.% H 2 concentration. A high sensitivity of roughly 165 pm % −1 is achieved as the H 2 concentration increases from 0% to 5.5 vol.%. This study demonstrates that H 2 -sensitive microstructures can be flexibly achieved by TPP of H 2 -sensitive inks, offering a solution for achieving on-chip direct laser writing of integrated H 2 microsensors.

In this study, a simple wet etching technique is developed by employing aqueous solutions of acetic acid and ultrasonic irradiation for the fabrication of a high-quality plastic optical fiber (POF) sensor. The effects of acetic acid concentration and temperature and ultrasonic power on the etching rate and surface morphology of the etched POFs are investigated. The transmission spectrum and sensitivity of the etched POF sensors are evaluated using glucose solutions. We discovered that the POF sensors, which are fabricated using an aqueous solution of acetic acid with a concentration of 80 vol. % under an ultrasonic power of 130 W and temperature of 25°C, exhibit good light transmission and a high sensitivity of 9.10 [(RIU)(g/L)]−1 in the glucose solutions.

Temperature is a critical parameter for evaluating battery safety during the process of charging and discharging. However, it is a challenge to monitor it accurately because batteries are used in various compact environments such as energy stations. In this study, β-NaYF4:Er3+/Yb3+@NaYF4 nanoparticles were used to fabricate an optical fiber temperature sensor for battery temperature monitoring. The temperature sensing characteristics of the optical fiber sensor were explored in the range of 293–373 K using fluorescence intensity ratio (FIR) technology which can improve the temperature monitoring accuracy. The maximum relative sensitivity of the optical fiber sensor was 1.62% K−1 at 293 K and the temperature detection limit was within ±0.5 °C. By embedding the prepared sensor in a Li-ion battery, the proof of concept was obtained for monitoring the internal temperature of a battery with upconversion nanoparticles (UCNPs). A larger temperature variation was observed under a higher discharge rate. These results indicate that the prepared optical fiber sensor is an active tool for monitoring the thermal behavior and improving the safety of the battery.

An integrated aerodynamic three-hole pressure probe (THP) based on a fiber-optic tip sensor array for high-velocity flow field vector measurement is developed and demonstrated in wind tunnel testing. The sensor array consisting of three miniature pressure fiber-tip sensors is integrated into three pressure conduits inside top area of the THP, which serves to mitigate pneumatic pressure loss and is expected for a more reliable analysis of flow characteristics. Fast real-time data acquisition is implemented by a compact self-developed multichannel white light interferometry (WLI) interrogator. Well-calibrated maps of the fiber-optic THP are developed in a subsonic free-jet wind tunnel to derive the velocity vectors in a yaw angular range of ±15° at Mach numbers of 0.2 Ma (∼70 m/s), 0.5 Ma (∼170 m/s), and 0.8 Ma (∼300 m/s) while related flow characteristics are analyzed. This work is desired to provide a potential candidate for turbomachinery experimental investigation in fluid mechanics community.

An optical fiber toluene gas sensor working at room temperature is proposed based on CQDs@SiO 2 (-OH) porous film. The CQDs@SiO 2 (-OH) porous film was elaborated on the surface of the hollow core fiber (HCF) using the templating method, where the evanescent field is excited by a misaligned structure. The precursor solution formed by mixing CQDs with SiO 2 (-OH) enhances CQDs dispersion within the film, preventing aggregation and preserving active sites. Experimental results indicate that the gas-sensitive layer doped with CQDs demonstrates a sensitivity of 5.1 pm/ppm to toluene gas at room temperature, which is approximately 3.13 times greater than that of the SiO 2 (-OH) porous film. Additionally, it demonstrates a response time of 12 s and a limit of detection (LOD) of 3.9 ppm. The gas sensing mechanism is thoroughly investigated using DFT, exploring the electronic distribution of the gas-sensitive layer before and after CQDs doping and analyzing the sensitization mechanism. This study presents a novel approach for toluene gas detection at room temperature using an optical fiber sensor.

Background The concentration of cytochrome C is demonstrated to be an effective indicator of the microbial corrosion strength of metals. Traditional cytochrome C sensor can detect cytochrome C with a low detection limit, but their use is limited by their high cost, cumbersome operation, and susceptibility to malignant environments. In addition, studies on the monitoring of cytochrome C in the field of microbial corrosion has still not been carried out. Therefore, there is a need for a highly sensitive, selective, low-cost, anti-interference, and stable cytochrome C sensor with online monitoring and remote sensing capabilities for in-situ measurement of microbial corrosion strength. Results This paper proposed a highly sensitive label-free fiber-optic sensor based on Mach-Zehnder interferometer (MZI) for in-situ measurement of the microbial corrosion marker cytochrome C. Two-dimensional Ti 2 C-MXene material is uniformly immobilized onto the surface of the sensing area to improve the sensitivity, hydrophilicity , and specific surface area of the sensing area, as well as to facilitate the immobilization of specific sensitive materials. The cytochrome C antibody is modified on the surface of Ti 2 C-MXene to specifically recognize cytochrome C, whose concentration variation can be measured by monitoring the spectral shift of MZI sensor. Results demonstrate a measurement sensitivity of 1.428 nm/μM for cytochrome C concentrations ranging from 0 to 7.04 μM. The detection limit of the sensor is calculated to be 0.392 μM with remarkable performance, including selectivity , stability, and reliability. Besides, the measurement result of the proposed sensor in real microbial corrosive environment is consistent with that of the ideal environment. Significance and novelty This is the first instance of achieving in-situ and label-free measurement of cytochrome C by using a fiber-optic MZI sensor, which undoubtedly provides a feasible solution for the effective monitoring of microbial metal corrosion in the environment.

A ratiometric fluorescence fiber-optical sensor system (RFFS) merging a Y-type optical fiber spectrometer and CdTe QDs composite functionalized with glutathione and mercaptopropionic acid (GMPA@CdTe-QDs) for highly selective and on-site detection of ciprofloxacin (CIP) in environmental water samples was designed. Our preliminary results suggested that the red fluorescence of the synthesized GMPA@CdTe-QDs was effectively quenched by CIP. Based on this, the RFFS/GMPA@CdTe-QDs system was successfully fabricated and used for highly selective and rapid detection of CIP on site in the concentration range from 0 to 45 μM with the detection limit of 0.90 μM. The established method exhibited good interference resistance to the analogues of CIP and provided a great potential platform for real-time detection of CIP residues in environmental water. In addition, the fluorescence quenching mechanism of GMPA@CdTe-QDs by CIP was also investigated by means of temperature effect, fluorescence lifetime, ultraviolet (UV) visible absorption, and fluorescent spectra. Our results suggested clearly that the red fluorescence of GMPA@CdTe-QDs was quenched by CIP via the photoinduced electron-transfer (PET) mode.Keywords:ratiometric fluorescence;optical fiber sensor;GMPA@CdTe-QDs;ciprofloxacin;on-site detection

A micro-nanostructure-based surface-modified fiber-optic sensor has been developed herein to selectively detect hydrogen peroxide (H2O2). In our design, phenylboronic ester-modified polymers were used as a modified cladding medium that allows chemo-optic transduction. Sensing is mechanistically based on oxidation and subsequent hydrolysis of the phenylboronic ester-modified polymer, which modulates hydrophobic properties of fiber-optic devices, which was confirmed during characterization of the chemical functional group and hydrophobicity of the active sensing material. This work illustrates a useful strategy of exploiting principles of chemical modifications to design surface-wettable fiber-optic sensing devices for detecting reactive species of broad relevance to biological and environmental analyses.

In this work, a colorimetric methodology was developed for free chlorine determination by constructing a fiber-optic sensor (FOS) which was designed by using a small LED as light source and two silica fibers as light transmission elements. Then the FOS was integrated with the sequential injection lab-on-valve (SI-LOV) manifold to fabricate a FOS-SI-LOV system for free chlorine detection. The colorimetric determination was based on the reaction between N , N -diethyl- p -phenylenediamine (DPD) reagent and free chlorine, which would produce a chromophore showing maximum absorbance at 511 and 551 nm and detected by a micro spectrometer detector. By choosing a green LED with emission wavelength at 520 nm as light source, the chlorine concentration could be simply evaluated according to Beer's law. The developed FOS-SI-LOV system showed improved performances of wide linear range (10–400 μg L −1 ), low detection limit (3.5 μg L −1 , 3σ), fast analysis (6.85 s) and excellent repeatability (0.0083 RSD, n=8) for chlorine determination. The proposed FOS-SI-LOV system has been applied to on-line and real-time chlorine determination in different water samples with excellent selectivity. Furthermore, this FOS-SI-LOV methodology provided a colorimetric and fluorescence detection platform for other hazardous species monitoring in water environment based on Beer's law and Stern-Volmer relationship, respectively.

Accurate detection of triglycerides (TGs) is important for the prevention and monitoring of dyslipidemia and for understanding the mechanisms of metabolic diseases. In this article, an ultrasensitive label-free sensor for measuring TGs based on an exposed-core optical fiber is presented. The sensor head was formed by splicing a single-mode optical fiber, a multimode optical fiber, and an exposed-core fiber in a Mach–Zehnder interferometer configuration. The Mach–Zehnder interference (MZI) occurs between the exposed core of the fiber, which is only micrometer in size, and the external environment. This allows the light path to pass directly through the liquid sample, resulting in an ultrahigh refractive index sensitivity of 13300 nm/RIU in the refractive index range of 1.331–1.332. In addition, lipase is immobilized on the optical fiber sensor to measure the concentration of TGs by detecting the change in the refractive index of the sample solution caused by the hydrolysis of TGs by lipase. The results showed that this sensor can specifically detect the concentration of TGs with a sensitivity of 1.72 nm/nM and a detection limit of 35 pM. It has the potential to revolutionize the diagnosis and monitoring of TGs and thus impact the prevention and treatment of dyslipidemia and other metabolic diseases.

As a low-density lipoprotein, tributyrin plays a vital role in food safety and human health. In this work, we first proposed a novel high-performance tributyrin sensor made by supporting zeolitic imidazolate framework-8 (ZIF-8) and lipase onto the optic fiber sensor based on the surface plasmon resonance (SPR) principle. After adsorption of lipase within the ZIF-8 framework, through a rapid aqueous synthesis method, a thin and dense ZIF-8 film can be uniformly formed and stably and tightly bonded to the surface of the optical fiber sensor. ZIF-8 is one of the metal–organic frameworks (MOFs), which not only has the high porosity and specific surface area of MOFs, but also shows good affinity with lipase. The experimental results show that the proposed sensor can achieve the specific detection of tributyrin in the linear range of 0.1–3 mM, the sensitivity is 14.75 nm/mM, with a detection limit of 0.096 mM. The sensor proposed in this article for the first time using ZIF-8/lipase composite material to detect tributyrin has an accuracy of more than 83% in sample detection at the range of 0.1–3 mM. In addition, the stability test of the proposed sensor is as good as 0.47 nm, and the selectivity (in the presence of glycine, acetylcholine, glucose, and urea) of the sensor was analyzed. The sensor proposed in this article has the advantages of a low sample consumption of $100~\mu \text{L}$ , high sensitivity, simple structure, and label-free measurement. This method provides a new route for the rapid and reliable detection of tributyrin, which has potential applications in medical research and clinical diagnosis.

This work proposes an optical fiber copper ion sensor, which is fabricated by an ion-imprinted sodium alginate/graphene oxide (SA/GO) hydrogel and single-mode fiber (SMF). This sensing Fabry–Perot Interferometer (FPI) achieves −1.98 nm/(mg/L) sensitivity with 0.998 linearity. To achieve higher sensitivity, we add a reference FPI to create a Vernier effect. We achieve 19.58 nm/mg/L sensitivity and 0.989 linearity at a concentration range of 0 mg/L–1.4 mg/L. It was 9.9 times higher than that of a single-sensing FPI. The experimental results also demonstrate that when the FSR values of two FPIs are closer, the higher response sensitivity is achieved. The sensor also has good measurement repeatability and dynamic response. In addition, the experimental results of response selectivity show that its response sensitivity to copper ions is significantly higher than other six types of ions, including iron ions, lead ions, magnesium ions, manganese ion, zinc ions, chromium ions. The copper ion is also mixed with six types of ions to deeply investigate the response selectivity. Good response selectivity and cross-responding are demonstrated by experimental results.
