Abstract：Sensor array is a powerful means of molecular identification developed based on the understanding of animal olfactory system, which consists of a series of sensing units, and realizes the identification and detection of specific substances through the characteristic maps generated by the response of each sensing unit to the sample, especially for the identification of mixed samples, which has outstanding advantages. Among them, fluorescence sensor arrays have become the focus of sensor array development in recent years due to their advantages of high sensitivity, no need for reference system, and rich output signals. In this paper, the design strategy and sensing mechanism of fluorescent sensor arrays and their applications in environmental monitoring and food analysis are reviewed.
