Abstract Hydrazine had important applications in medicine, the chemical industry, and agriculture, but hydrazine pollution was also very harmful to human beings. Chemists have reported many types of fluorescent probes. However, it still challenging continuously improve selectivity sensitivity Here, we designed synthesized a novel NH 2 probe based on neighboring group participation (NGP). We choose bromine chlorine as respectively. The good anti‐interference ability. detection limits were 0.027 µM (probe A) 0.054 B). sensing mechanism confirmed by 1 H NMR, 13 C FT‐IR. Theoretical calculation showed that energy barrier could be reduced NGP. In terms application, has function quantitative actual water samples.

A new chemodosimeter SWJT-31 with an aggregation-induced emission (AIE) effect was designed and constructed. Upon increasing the water fraction in solution, it exhibited typical AIE, which showed bright red fluorescence at 610 nm. could sensitively specifically recognize hydrazine by TICT LOD of 33.8 nM, much lower than standard USEPA. portable test strip prepared using also developed for visual detection hydrazine. Eventually, successfully used samples HeLa cells.

A Highly Effective Curcumin-Based Fluorescent Probe with Single-Wavelength Excitation for Simultaneous Detection and Bioimaging of Cys, Hcy and Gsh

Опубликована: Янв. 1, 2024

Cysteine (Cys), homocysteine (Hcy) and glutathione (GSH) act as significant roles in many physiological processes, their abnormal proliferation will cause multiple diseases including Alzheimer's disease, Parkinson's Cardiovascular atherosclerosis, soft tissue damage. However, It is challenging work to develop a efficient method for differentiating detecting GSH, Cys Hcy because of similarity structures functions. In this work, smart fluorescent probe FBCN based on curcumin was rationally devised developed by etherifying the phenol hydroxyl group FBC with NBD-Cl, which emitted strong green at 516 nm. distinguished from Cys/GSH naked eyes color variation solution sunlight. Meanwhile, GSH induced powerful fluorescence quenching solution, but transformed luminous yellow accompanied emission wavelength redshifted nm 540 or 553 existence Cys, respectively. Probe had outstanding sensitivity anti-interference, low detection limit (61.6 nM, 77.7 0.29 µM corresponded Hcy, respectively), short response time (the 1 min, 2 min 5 respectively). The DFT calculation HRMS verified sensing mechanism biothiols. addition, successfully utilized detect three biothiols levels living cell zebrafish.
