Abstract
A novel rhodamine-benzothiazole fluorescent chemosensor, bridged with a thiophene unit, is designed for the turn-on detection of Hg and Cu. Noteworthy findings include impressively low limits of detection (0.007 μM for Hg and 0.013 μM for Cu), a determined sensing mechanism involving spirolactam ring opening and hydrolytic cleavage, consistent 1:1 binding stoichiometry for both metal ions and an optimal pH of around 6. The sensor’s practical applicability is demonstrated through successful implementation in HeLa cells and zebrafish, along with effective analyte recovery in various water samples. This work advances the field by providing a highly sensitive and versatile chemosensor for environmental and biological applications.
期刊介绍：
The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field.
Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
