A coumarin-quinoline-derived fast and highly sensitive turn on fluorescent probe for sniffing sulfite in food, living cells and zebrafish

A dioxaborine-based ratiometric fluorescent probe derived from 2-hydroxy-3-pinanone for H2O2 detection and application in food samples and bioimaging.

Probe DPBO possessed favorable biocompatibility and excellent potential for practical applications in both food safety and bioimaging contexts, and was successfully employed for the quantitative detection of H2O2 in diverse real-world food and beverage samples with high accuracy and high recovery rates.

A Xanthene-Scaffold Fluorescent Probe for Dual-Mode Fluorescence-Colorimetric Detection of Hydrazine and its Application in Environmental Analysis.

A novel 4H-furo[3,2-b]pyrrole derivative-based fluorescent probe for rapid and sensitive detection of hydrazine in environmental samples.

A novel fluorescent probe EFC, featuring a 4H-furo[3,2-b]pyrrole scaffold, was designed, synthesized, and investigated for its optical properties. EFC was identified as a novel hydrazine probe, which undergoes a nucleophilic substitution reaction with hydrazine. In the presence of hydrazine, EFC exhibits a color change...

A Coumarin-Derived Fluorescent Probe For The Rapid Detection Of Nitroaromatic Explosives TNP and PYX.

A Novel Benzimidazole-π-Bridge-Dicyanoisophorone-Type Near-Infrared Fluorescent Probe for Rapid Monitoring of Hydrogen Sulfide Based on a Cascade Thiolysis Strategy.

Herein, we designed a dual DNP-caged near-infrared probe, N-Bu-DCIB-2DNP, by conjugating dicyanoisophorone (DCI) with an N-alkylated benzimidazole (B) through double vinylene linkers. This probe features two responsive sites-the DNP ether on the donor and the DNP-functionalized electron-deficient quaternary carbon on t...

A benzothiazole-based fluorescent probe for rapid spectroscopic detection of cysteine and bioimaging in cells and zebrafish.

Results indicate that HBT-D provides a simple fluorescence method for Cys detection in biological systems and exhibited low cytotoxicity and was successfully used for fluorescence imaging of Cys in HeLa cells and zebrafish.
