“…The colorimetric method is advantageous because of easy readout with the naked eye and potential for high throughput formats. Being organic in nature, these sensors are sometimes associated with certain limitation such as less stability, use of high concentration and also do not have a limit of detection (LOD) as low as a fluorescent-or luminescent-based approach [24][25][26][27][28]. Moreover, these are incapable of removing the ions from the medium owing to their diffusive nature which is further rectified with nano-tool technique.…”

We have synthesized sulfonamide based nano-composites of SiO2 and TiO2 for selective and sensitive determination of toxic metal ion Hg2+ in aqueous medium. Nano-composites (11) and (12) were morphologically characterized with FT-IR, solid state NMR, UV-vis, FE SEM, TEM, EDX, BET, pXRD and elemental analysis. The comparative sensing behavior, pH effect and sensor concentrations were carried out with fluorescence signaling on spectrofluorometer and nano-composites (11) and (12), both were evaluated as “turn-on” fluorescence detector for the toxic Hg2+ ions. The LODs were calculated to be 41.2 and 18.8 nM, respectively of nano-composites (11) and (12). The detection limit of TiO2 based nano-composites was found comparatively lower than the SiO2 based nano-composites.

Mercury has strong biological toxicity and poses great harm to human health and the environment. Fluorescent probes have been widely applied in the detection of mercury ion in recent years, due to these probes with high sensitivity, high selectivity, and real-time monitoring. Owing to the advantages of small molecules such as structural diversity, good repeatability, easy modification, and clear sensing mechanisms, many organic small molecular fluorescence probes for detecting mercury ion have also been developed. According to the different reaction mechanisms between probes and mercury ion, these organic small molecular fluorescence probes can be classified into two categories based on coordination type reactions and bond breaking type reactions. The research progress of organic small molecular fluorescence probes used to detect mercury ion in the past five years is summarized in detail. This provides a reference for their further development in the future, especially for the new turn-on type reactive organic small molecular fluorescence probes for detecting mercury ion by utilizing the characteristic reactions.
