“…In aqueous media, mercury can be transformed into methylmercury, a powerful neurotoxin, which can be accumulated and ingested by humans through the food chain [143,144,145]. In the human body, methylmercury can lead to serious symptoms, such as cognitive and motor disorders, neurological impairments, brain damage, and even death [146,147,148]. These environmental and biological problems have prompted the rapid development of techniques for sensing mercury [149,150,151,152,153].…”

Metal–organic frameworks (MOFs), as a class of crystalline hybrid architectures, consist of metal ions and organic ligands and have displayed great potential in luminescent sensing applications due to their tunable structures and unique photophysical properties. Until now, many studies have been reported on the development of MOF-based luminescent sensors, which can be classified into two major categories: MOF chemosensors based on reversible host–guest interactions and MOF chemodosimeters based on the irreversible reactions between targets with a probe. In this review, we summarize the recently developed luminescent MOF-based chemodosimeters for various analytes, including H2S, HClO, biothiols, fluoride ions, redox-active biomolecules, Hg2+, and CN−. In addition, some remaining challenges and future perspectives in this area are also discussed.

“…46 As shown in Table 1, the performances of AuNCs@DCTX as a Cu 2+ sensor were compared with those of other nanocluster-based uorescence probes, and it was found that the proposed sensor was highly sensitive for Cu 2+ detection. 38,39,[44][45][46][47][48][49][50] The selectivity of AuNCs@DCTX towards Cu 2+ was evaluated by measuring the uorescence response of AuNCs@DCTX aer adding 20 mM of different common metal cations (Zn 2+ , Al 3+ , Ni 2+ , Co 2+ , Pb 2+ , Cr 3+ , Cd 2+ , Mn 2+ , Mg 2+ , K + , Bi 3+ , Ba 2+ , Ca 2+ , Fe 3+ and Hg 2+ ) without and with 20 mM Cu 2+ , separately.

“…These CEW-Au NCs selectively detected Hg 2+ in the presence of Cu 2+ ions by EDTA masking approach. Citrate-stabilized stannous ions (Sn(II)-citrate) have been used as reducing and capping agents to obtain Au NCs for simultaneous detection of Cu 2+ and Hg 2+ ions [53]. In this system, Chen et al stated that Au NCs acted as dual spectroscopic probes that utilized both fluorescence (FL) quenched by Cu 2+ and resonance light scattering (RLS) enhanced by Hg 2+ ions.…”

Studies of metal nanocluster (M-NCs)-based sensors for specific analyte detection have achieved significant progress in recent decades. Ultra-small-size (<2 nm) M-NCs consist of several to a few hundred metal atoms and exhibit extraordinary physical and chemical properties. Similar to organic molecules, M-NCs display absorption and emission properties via electronic transitions between energy levels upon interaction with light. As such, researchers tend to apply M-NCs in diverse fields, such as in chemosensors, biological imaging, catalysis, and environmental and electronic devices. Chemo-and bio-sensory uses have been extensively explored with luminescent NCs of Au, Ag, Cu, and Pt as potential sensory materials. Luminescent bi-metallic NCs, such as Au-Ag, Au-Cu, Au-Pd, and Au-Pt have also been used as probes in chemosensory investigations. Both metallic and bi-metallic NCs have been utilized to detect various analytes, such as metal ions, anions, biomolecules, proteins, acidity or alkalinity of a solution (pH), and nucleic acids, at diverse detection ranges and limits. In this review, we have summarized the chemosensory applications of luminescent M-NCs and bi-metallic NCs.
