Fluorescent sensor arrays for metal ions detection: A review

The abnormal concentration of the metal ions in the environment threatens the health of Earth and human beings. At present, many methods have been employed to detect metal ions. Among this, the fluorescent sensor array based on pattern recognition has aroused tremendous attention. Unlike traditional lock-key type fluorescent probes, the sensor array can accomplish the detection of various metal ions simultaneously. Meanwhile, it has significant advantages such as excellent sensitivity, tunable emission range and high-throughput analysis. In this review, the fluorescent sensor arrays for metal ions detection over the last few years will be introduced. The analytical performances and the detection scopes of the arrays are discussed, as well as the approaches to realizing the high-accuracy discrimination and high-sensitivity detection.

Automated summary

The fluorescent sensor array is an emerging method for metal ions detection, with advantages such as excellent sensitivity and high-throughput analysis, capable of simultaneously detecting multiple metal ions. This technology has made progress in recent years, significantly impacting the detection scope and accuracy of metal ions.
