Introduction The construction of nanomaterial-based ratiometric detection systems usually requires covalent modification, which undergoes reactive environments and may change the natural properties supporting nanomaterials. Methods In this study, dualemissive fluorescein-decorated gold nanoclusters (F-Au NCs) through cyclodextrin-supported host–guest interaction (non-covalent modification) are explored as Hg 2+ nanoprobes d 10 –d -interactioncaused fluorescence quenching Au NCs. Results Discussion fluorescein decoration only provides a fluorescent internal reference but does not -Au NCs affinity nature. Ratiometric selective is achieved proposed F-Au NC probes with limit 15 nM. analysis in river water samples small relative standard deviations validates practical application these probes.
