Water-soluble gold nanoclusters-based fluorescence probe for highly selective and sensitive detection of Hg2+

Characterization of a highly Al3+‐selective fluorescence probe based on naphthalimide‐Schiff base and its application to practical water samples

“…The contents of Al 3+ tested were in good agreement with the spiked contents and the recovery of Al 3+ for the two samples was about 100%. The present probe seems useful for the determination of Al 3+ ion in real samples …”

An aptasensor for the label-free detection of thrombin based on turn-on fluorescent DNA-templated Cu/Ag nanoclusters

“…[29][30][31][32] Moreover, the quantum yield and uorescence emission of DNA-NCs can be altered by adjusting the length and sequence of DNA. Hence, DNA-NCs can be designed as uorescence probes for the assay of metal ions, 33,34 various biomolecules 34,35 and in vitro or in vivo imaging. 5,36 It was reported that the uorescence of non-emissive DNAtemplated Ag NCs (DNA-Ag NCs) can signicantly enhance in proximity to each other or by interacting with different enhancer sequences.…”

Luminescent turn-on detection of Hg(II) via the quenching of an iridium(III) complex by Hg(II)-mediated silver nanoparticles

“…Viewed as an alternative approach to these methods, luminescence assays possess promising advantages, such as rapid response, high sensitivity, and simple manipulation 16 – 18 . Pioneer studies have reported many luminescent probes, including organic molecules 19 , quantum dots (QDs) 20 , and metal nanoclusters 21 , 22 for the detection of Hg(II). Nevertheless, most of these methods show drawbacks, including poor selectivity and sensitivity, complicated synthetic procedures, low stability in aqueous media and a turn-off signal output 20 – 22 , leading to strong desire of developing alternative approaches.…”
