Abstract:

Significance Fiber-based colorimetric gas sensor is a new sensing technology that enables visual detection of gas pollutants based on color changes, which has the advantages of portability, high sensitivity and low cost. As air pollution becomes a growing problem, conventional gas detection methods rely on expensive equipment and specialized personnel for real-time monitoring. This paper systematically review the sensing principles, response materials, and preparation methods (such as impregnation method, electrospinning method, etc.) of fiber-based colorimetric sensors and their applications in the detection of chemical warfare agents, volatile organic compounds (VOCs), hydrogen sulfide (H2S) and ammonia gas (NH3), together with the challenges and future development directions of fiber-based colorimetric sensors. This research provides an important theoretical basis and technical reference for the development of high-performance and wearable gas sensors, and is of great significance for promoting the development of environmental safety monitoring, industrial protection and smart wearable devices.

Progress This paper systematically reviews the latest progress and representative achievements of fiber-based colorimetric gas sensors. In terms of materials, a variety of response systems based on dyes (e.g., chlorophenol red, bromocresol violet), noble metals (silver, gold nanoparticles) and fluorescent probes have been developed, which significantly improve the sensitivity and selectivity of the sensor. In terms of preparation process, electrospinning, wet spinning, freeze-drying and novel spinning technologies have been innovatively used for constructing fiber-based sensors with high specific surface area. In terms of applications, detection of toxic gases such as chemical warfare agents, NH3, H2S and have been achieved, and the potential of wearable applications was demonstrated through patterned textile integration. Representative achievements include LiCl/cellulose-based fibers for NH3 sensing, ionic liquid/lead acetate nanofiber yarns for H2S monitoring, and so on. These advances provide an important foundation for the development of portable and intelligent fiber-based gas sensing devices.

Conclusion and Prospect This study systematically reviews the latest research progress of fiber-based colorimetric gas sensors, focusing on their application potential in the fields of environmental monitoring and wearable devices. The results show that fiber-based colorimetric gas sensors show excellent performance in the detection of harmful gases such as NH3 and H2S. However, there are still three major problems in current research: the lack of environmental stability of colorimetric sensing materials, the immaturity of mass production processes, and the susceptibility to cross-interference when multifunctional integration. Based on the existing results, this paper puts forward three important points: fiber-based sensors have the potential to be served as portable gas-monitoring devices, material and method innovation is the key to breaking through performance bottlenecks, and intelligence is the future development direction. For instance, a proposed strategy can be conducted by strategically integrating heterogeneous responsive materials and engineering multi-analyte recognition units. These innovative platforms enable simultaneous monitoring of gaseous species, ionic compounds, and biomolecules within complex environmental and biological matrices. Also, incorporating advanced flexible electronics, microfluidic networks, and wireless communication modules can significantly enhance the functional capabilities of fiber-based colorimetric sensors. In terms of application, fiber-based colorimetric sensors with customizable designs hold significant potential for addressing interindividual variability in physiological monitoring. By controlling sensor composition and response properties, these wearable platforms enable real-time, continuous tracking of critical biomarkers, including disease-related analytes, therapeutic drug levels, and nutritional metabolites, which will provide more accurate diagnostic criteria and treatment effect evaluation methods for personalized medicine and facilitate the development of precision medicine.
