Highly sensitive simultaneous detection of mercury and copper ions by ultrasmall fluorescent


Fluorescent metal nanoclusters (NCs) have given rise to a new class of fluorescent nanomaterials for the detection of heavy metals. Here, we design a simple, rapid and highly sensitive sensing nanosystem for the detection of Hg and Cu based on fluorescence quenching of ultrasmall DNA–Ag NCs. The fluorescence intensity of DNA–Ag NCs was selectively quenched… (More)
