Abstract:

Fluorescent film sensors have gained extensive attention in the past few decades because of their notable advantages such as high sensitivity, real-time detection, abundant fluorescence signals, easier device implementation, etc. With the fast development and promotion of microfabrication technology, integrated manufacturing, flexible device and Internet of Things, film-based fluorescent sensors have become one of the hot points of sensor studies. Based on the recent progress in our research, this article briefly reviews the development and applications of low-molecular mass compounds-based fluorescent film sensors, of which the applications in the vapor phase detection of explosives, illicit drugs, volatile organic contaminates and some signal molecules of diseases are specially addressed. In addition, problems and challenges limiting the construction of the film sensors are pointed out, and the futures of the relevant studies are prospected.

Key words: low-molecular mass compounds, fluorescent films, gas sensing, fluorescent sensors
