Abstract:

A significant quantity of palladium is widely used in various materials, such as pharmacy, fuel cell, dental alloys and electronics, which inevitably cause its residues in the environment with pernicious effect on the body health. Therefore, it is of great significance to the detection and recognition of palladium. Owing to simple operation, high sensitivity, high sensitivity, low limit of detection, excellent high spatial and temporal resolution and especially nondestructive characteristics, fluorescent technique has been paid special attention. A variety of methods are discussed and introduced, which are applied in the design of fluorescent probes developed to detect the low concentration of palladium as well as mechanism of action in this review. Subsequently, the type of fluorescent probes mainly is classified into three kinds:quenching, turn-on and ratio based on response models. Although the molecular design of fluorescence probes of palladium has made an important progress, the response time of probes towards palladium is still uncontrollable. Additionally, it is not ideal for most fluorescent sensors to the detection of palladium in complex system. Developing rapid, high sensitive and selective fluorescent probes are suggested for future research to the detection of palladium ions in complex bio-system.
