Vitamin B₆ Cofactor–Derived AIEE Active Luminogen for Detecting Ciprofloxacin and Levofloxacin

Luminescence, Год журнала: 2025, Номер 40(4)

Опубликована: Апрель 1, 2025

The present study reports an aggregation-induced emission enhancement (AIEE) luminogen (AIEEgen) NPL derived by condensing equimolar amount of vitamin B6 cofactor pyridoxal 5'-phosphate (PLP) and 3-hydroxy-2-naphthohydrazide. AIEE characteristics was explored in mixed DMSO-HEPES buffer (pH 7.4, 10 mM) medium. weakly yellow emissive DMSO turns to cyan as the fractions HEPES (fHEPES) increased from 10% 95% DMSO. results dynamic light scattering (DLS) scanning electron microscope (SEM) analysis supported formation self-aggregates NPL. When fluorescence spectral changes AIEEgen (fHEPES 95%, λex = 370 nm, λem 485 nm) were examined adding different drugs, presence ciprofloxacin levofloxacin intensity found UV-Vis absorption, DLS, zeta potential SEM new complex species between selective drugs. detection limits for estimated low 2.84 0.21 μM, respectively. Additionally, analytical usefulness investigated quantifying real human blood serum.

Excited state intramolecular proton transfer dual emission Schiff bases for metal detection and cell imaging

Applied Spectroscopy Reviews, Год журнала: 2023, Номер 59(7), С. 959 - 988

Опубликована: Ноя. 7, 2023

Fluorescent probes incorporating the excited-state intramolecular proton transfer (ESIPT) phenomenon have emerged as versatile tools in scientific research. These exhibit dual emission, resulting from unique of a within molecule upon excitation. This property makes ESIPT-based Schiff bases highly attractive for metal detection, cell imaging, and sensing biologically important molecules. In spectral changes interaction with ions enable development sensitive selective sensors. For their photophysical properties make them ideal labeling cellular components facilitating multicolor imaging. biomolecules, offer detection interactions enzymatic activities. Integration these holds great promise applications environmental monitoring, biomedical research, healthcare. review focuses on photoluminescent application ESIPT emission ions, relevant molecules
