Abstract Fluorescent molecular probes have gained significant attention due to their exceptional attributes, such as enhanced specificity, sensitivity, and reversibility. This review explores how organic probe molecules' fluorescence properties change when metal ions like Hg 2+ bind the receptors. The alteration in results from distinct photophysical mechanisms photoinduced electron transfer, proton energy charge excimer formation, aggregation‐induced emission, C═N isomerization etc. Besides, induce chemical reactions resulting changes structural conformation properties. As a result, this effect specifically affects signal of molecules, which is beneficial for advancing sensor technology developed detect contamination. Focusing on environmental pollution biological sample analysis, study highlights applying fluorescent techniques using chromophores heavy ions, particularly ions. Thus, dyes with modifiable functional groups ensure precise detection offering robust platform monitoring public health safety. We examine capacities, sensing mechanisms, limits, strategies, methodologies utilized. article provides insights into efficacy progress domain sensors detecting

Fluorescent/Colorimetric Dual-Mode Discriminating Gln and Val Enantiomers Based on Carbon Dots

Analytical Chemistry, Год журнала: 2023, Номер 95(39), С. 14573 - 14581

Опубликована: Сен. 20, 2023

Discrimination and quantification of amino acid (AA) enantiomers are particularly important for diagnosing treating diseases. Recently, dual-mode probes have gained a lot research interest because they can catch more detecting information compared with the single-mode probes. Thus, it is great significance to develop sensor realizing AA enantiomer discrimination conveniently efficiently. In this work, carbon dot L-TCDs were prepared by N-methyl-1,2-benzenediamine dihydrochloride (OTD) l-tryptophan. With assistance H2O2, show an excellent performance glutamine (Gln) valine (Val) in both fluorescent colorimetric modes. The fluorescence enantioselectivity Gln (FD/FL) Val (FL/FD) 5.29 4.13, respectively, (ID/IL) (IL/ID) 13.26 3.42, individually. chiral recognition mechanism was systematically studied. be etched participation results different amounts released OTD, which provides signals identifying quantifying Val. This work convenient flexible sensing strategy discriminating enantiomers, expected value facile high-throughput recognition.
