Article Abstract

In this paper, we reported a coumarin-based fluorescent probe for selective detection of HO/SO derivatives via ICT process. To the best of our knowledge, it was few reported with the same probe to enable visual detection of HO/SO derivatives in vivo and in vitro. HO and SO were selectively sensed over other analytes, and the probe displayed 20-fold and 220-fold relative fluorescence intensity respectively, as well as the good linear relationship and the excellent detection limits of 2.7 * 10 nM and 19.3 nM. Furthermore, the probe was successfully used for fluorescence imaging of the HeLa cells and the mice to monitor exogenous and endogenous HO and SO, suggesting its potential biomedical application for investigation and detection the intermediate indicator of oxidative stress in vitro and in vivo.

The dynamic monitoring of cell death processes remains a significant challenge due to the scarcity of highly sensitive molecular tools. In this study, two hemicyanine-based probes (5a-5b) with D-π-A structures were developed for organelle-specific viscosity monitoring. Both probes exhibited correlation with the Förster-Hoffmann viscosity-dependent relationship (R > 0.

The antibiotic contamination in aquatic environments, particularly in aquaculture systems, poses substantial risks to ecological balance and human health. To address this issue, we engineered a novel ratiometric fluorescent probe utilizing dual-emission carbon dots (D-CDs) synthesized from sustainable biomass carrot and nitrogen-rich precursors (melamine and o-phenylenediamine) through an efficient one-pot hydrothermal approach. The D-CDs exhibited dual emission peaks at 425nm and 540 nm under 370nm excitation.

This work presents the development of a highly sensitive, selective, and efficient aptamer-based fluorescent sensor for detecting cortisol in human urine. Carbon quantum dots-nucleic acid aptamer (CQDs-Apt) synthesized with excellent photoluminescent properties and stability, were selected as the fluorescent probe. In the presence of MoS-NSs, CQDs-Apt adsorbed onto the surface of MoS-NSs via electrostatic and π-π interactions, leading to strong and rapid fluorescence quenching due to static quenching mechanism between them.

Molecules that exhibit excited-state intramolecular proton transfer (ESIPT) have demonstrated great promise in fluorescent probes. The electronic effect of substituents has an important influence on the ESIPT process. In this study, we investigated the effects of substituents on the ESIPT mechanism and the photophysical behavior of single-benzene fluorophore (SBF) derivatives with computational chemistry methods.

Alzheimer's disease (AD) is a neurodegenerative disease characterized by β-amyloid (Aβ) deposition, imposing significant social and economic burdens globally. Despite extensive efforts have been devoted to developing fluorescent probes for Aβ imaging, further improving the luminescent efficiency of prevailing probes still remains a significant challenge. Herein, we investigated the inner mechanism of constructing high-efficient Aβ probes via a structural cyclization strategy.
