Fluorescent Chemosensors as Precision Tools for Bioimaging and Environmental Monitoring: Advances, Challenges, and Future Directions.

1,8-Naphthalimide: A Versatile Platform for the Design of Fluorescent Probes Targeting Hydrogen Sulfide in Biological Systems

Hydrogen sulfide (H2S) has emerged as an important gaseous signaling molecule involved in numerous physiological and pathological processes, including redox regulation, inflammation, and cellular signaling. Accurate detection of H2S in biological systems is therefore essential for understanding its roles in health and...

Recent Advances in Camphor-Derived Small-Molecule Organic Fluorescent Probes.

Camphor, a naturally occurring bicyclic monoterpenoid, has attracted increasing interest as a structural scaffold for the construction of fluorescent probes owing to its rigid framework, facile functionalization, and favorable biocompatibility. In recent years, a variety of camphor-derived fluorescent probes have been...

A "turn-on" Fluorescent Probe with Ions-induced ESIPT for the Detection of Cd2+ and Zn2.

Developing an Aggregation-Induced Emission Enhancement (AIEE) type probe with enhanced emission through metal ion-induced methods has been a significant challenge. In this work, we synthesized an AIEE fluorescent chemosensor P1 via a Schiff base reaction by 8-hydroxyquinoline-2-carbaldehyde and 2,4-difluorophenylhydraz...

A heterocyclic chalcone-based fluorescent chemosensor for selective Cu(II) detection: mechanistic insights and preliminary bacterial imaging applications.

Chalcones are attractive scaffolds for fluorescent sensing applications in environmental and biological matrices. Herein, a heterocyclic arylchalcone-based fluorescent chemosensor (2-TIO) with pronounced intramolecular charge transfer (ICT) character was synthesized and spectroscopically characterized for selective Cu(...
