“…In one demonstration of this approach, the acridinone-appended silyated alkyne 2 was allowed to react with CH 3 HgX (X ) Cl, Br) in dichloromethane and in the presence of TBAF, and the resulting methylmercury acetylide 3 was detected by HPLC/UV (Figure 2a). 62 When excess 2 is employed,>85% formation of 3 occurs in 20 min at 20 °C. The sensitivity of this method is high; concentrations as low as 6 nM methylmercury were detected.…”

“…It is well known that Hg exists in natural waters as different species: Hg 0 , methyl-Hg, and inorganic Hg(II); however, the dominant toxic species in drinking waters is Hg(II). Various instrumental methods and techniques have been developed for Hg determination at low environmentally relevant concentrations like atomic absorption/emission spectrometry (AAS/AES) [3], atomic fluorescence spectrometry (AFS) [4,5], and high-performance liquid chromatography (HPLC) [6,7]. In spite of being very sensitive and precise for Hg determination, these methods often require a time-consuming sample preparation step as well as expensive instrumentation.…”

, and Ni 2+ ) do not interfere under the same conditions, due to the absence of oxidative activity of these ions, which guarantees the high selectivity of the proposed optical sensor towards Hg 2+ . The limits of detection and quantification were found to be 0.9 g L −1 and 2.7 g L −1 , respectively, and relative standard deviations varied in the range 9-12% for Hg content from 0.9 to 12.5 g L −1 and 5-9% for Hg levels from 25 to 500 g L −1 . The method was validated by analysis of CRM Estuarine Water BCR505. A possible mechanism of interaction between AgNPs and Hg 2+ for both concentration ranges was proposed on the basis of UV-Vis, TEM, and SAED analyses.

This review article mainly provides a critical evaluation of the ion and molecular recognition aspects along with the biomedical applications of the conjugates of carbohydrates published in the literature during the past ten years. Thus, the article primarily deals with the derivatives of carbohydrates, wherein these were selective towards the species of biological and ecological relevance as well as their utility in the medical research. The recognition has been monitored by different spectral techniques, such as, fluorescence and absorption spectroscopy and in some cases even visual colour changes. These were further supported by 1H‐Nuclear Magnetic Resonance, electrospray ionization mass spectrometry (ESI MS) and microscopy data. Over the past one decade, there has been a surge in the development and applications of the conjugates of carbohydrates in the field of chemosensors. The accelerated interest is mainly due to their water solubility, biocompatibility and selective and sensitive interactions exhibited by these towards ions and molecules of the type of examples included in this article. Owing to the presence of protein‐carbohydrate interactions, the carbohydrate conjugates have been employed for different biomedical applications such as antimicrobial activity, cell imaging and specific targeting. Therefore, in this article, the sensing and medical applications of the carbohydrate conjugates have also been discussed. For clarity, the main features have been conveniently divided into four sections, sensing of guest species, viz., metal ion, anion or amino acid and bio‐medical applications. While discussing the biomedical applications, such as, the imaging, specific targeting and anti‐disease activity of these conjugates in solution as well when they are attached onto solid surfaces have been covered. Overall, this article deals with the analysis of more than three dozen glyco‐based receptors demonstrated for selective sening of ions and molecular species along with their applications towards disease diagnosis and or prevention. Enough efforts were put to place these on a common platform and to compare these accordingly.
