The real-time detecting and monitoring of ethylene gas molecules could benefit the agricultural, horticultural and healthcare industries. In this regard, we comprehensively review the current state-of-the-art ethylene gas sensors and detecting technologies, covering from preconcentrator-equipped gas chromatographic systems, Fourier transform infrared technology, photonic crystal fiber-enhanced Raman spectroscopy, surface acoustic wave and photoacoustic sensors, printable optically colorimetric sensor arrays to a wide range of nanostructured chemiresistive gas sensors (including the potentiometric and amperometric-type FET-, CNT- and metal oxide-based sensors). The nanofabrication approaches, working conditions and sensing performance of these sensors/technologies are carefully discussed, and a possible roadmap for the development of ethylene detection in the near future is proposed.
乙烯气体分子的实时检测和监测将惠及农业、园艺和医疗保健行业。在这方面，我们全面综述了当前最先进的乙烯气体传感器和检测技术，涵盖配备预浓缩器的气相色谱系统、傅里叶变换红外技术、光子晶体光纤增强拉曼光谱、表面声波和光声传感器、可印刷光学比色传感器阵列以及各种纳米结构的化学电阻式气体传感器（包括电位型和电流型场效应晶体管、碳纳米管和金属氧化物基传感器）。我们仔细讨论了这些传感器/技术的纳米制造方法、工作条件和传感性能，并提出了近期乙烯检测发展的可能路线图。
