Abstract:With the continuous progress of industrialization, environmental pollution has become an increasingly prominent problem. The development of sensors and arrays specifically designed to detect different types of pollutants is significant for the management of environmental pollution and the protection of people"s health. In recent years, fluorescent molecule probes with high detection sensitivity and fast response have gradually become important tools for pollutant detection. Fluorescent sensing films prepared by fixing them on flexible substrates through physical or chemical methods are devices with huge potential for the detection of trace amounts of substances. They have series of advantages including simple operation, easy carrying, adjustable size, and non-polluting to the test system, especially it will greatly promote research on intelligent wearable materials, which have attracted widespread attention in recent years. This article mainly reviews the research status of flexible sensing films and devices based on fluorescent probe technology for the detection of common gaseous and liquid environmental pollutants in recent years. Moreover, some existing problems and future prospects in this field are summarized and discussed.
