A Novel Dual-Function Peptide-Based Fluorescent Probe With Large Stokes Shift for the Simultaneous Detection and Quantification of Ag(I) And Hg(Ii) Ions

Опубликована: Янв. 1, 2025

Achieving highly selective detections of Ag+ and Hg2+ is great importance because their excessive emission can cause many diseases. Herein, a novel large Stokes shift fluorescent probe DKT based on dansyl fluorophore modified peptide biomolecules (NH2-Thr-Lys-Thr-NH2) was successfully synthesized with high yield, which simultaneously detect (turn on) off) different response patterns in 100% aqueous solution. also enables quantitative detection LODs 37.1 nM 26.7 nM, respectively. Besides, ESI-HRMS spectra, Job's plot, fluorometric titration confirmed that the binding stoichiometry determined to be 2: 1 between Ag+/Hg2+. Moreover, has good fluorescence stability rapidly detected over wide pH range. Furthermore, applied three actual water samples, tea samples watermelon juice, exhibited potential for accuracy environmental monitoring quality control. Additionally, results bioimaging showed had significant distinguishing ability living cells zebrafish. More importantly, smartphone platform not only provides reliable new method field Hg2+, but expands its application prospect heavy metal ions pollution detection.

Abstract A simple naphthalimide‐based fluorescent probe was designed and synthesized for the determination of mercury ion (Hg 2+ ). The showed a noticeable fluorescence quenching response Hg . When added with , intensity at 560 nm remarkably decreased color changed from yellow to colorless under ultraviolet (UV) light. had notable selectivity sensitivity displayed an excellent sensing performance when detecting low concentration (19.5 nM). binding phenomenon between identified by Job's method high‐resolution mass spectrometry (HRMS). Moreover, not only utilized identify in real samples satisfactory results (92.00%–110.00%) but also successfully used bioimaging cells zebrafish. recognition mechanism has been verified transmission electron microscopy (TEM) first time. All that could be as potent useful tool detection
