Applications of Metal Nanoclusters in Environmental Monitoring / 分析化学

Novel optical materials are crucial for environmental monitoring. Metal nanoclusters ( metal NCs) , typically consisting of several to tens of metal atoms, have attracted more and more attention for recent years. Due to their ultrasmall size, strong fluorescence, low toxicity, excellent stability and unique core-shell structure, metal NCs have been considered as promising optical materials for the construction of excellent fluorescent sensors. In this review, we mainly focus on the recent progress in their applications in environmental monitoring, including the detection of pH, heavy metal ions, inorganic anions and nitroaromatic explosives.
