Small-molecule fluorescent probes are attractive and versatile materials for studying
biological systems.(1-6) They can be easily loaded into cells and rapidly detect biological …

Chromogenic and fluorogenic probes may be described as the reagents that can interact
with analytes (targets) accompanied by the changes of their spectroscopic (chromogenic, or …

Coordination chemistry plays an essential role in the design of photoluminescent probes for
metal ions. Metal coordination to organic dyes induces distinct optical responses which …

Two photons are better than one: This principle applies to a wide range of applications,
ranging from engineering to physiology. Recent advances in our understanding of the …

The essential trace element zinc (Zn) is widely required in cellular functions, and abnormal
Zn homeostasis causes a variety of health problems that include growth retardation …

It is still a significant challenge to develop a Zn2+-selective fluorescent sensor with the ability
to exclude the interference of some heavy and transition metal (HTM) ions such as Fe2+ …

Approximately one third of the human proteome contains metal cations, either in the form of
cofactors with catalytic functions or as structural support elements. 1, 2 To guarantee a …

Many aspects of cell metabolism are controlled by acidic pH. We report a new family of small
molecule and ratiometric two photon (TP) probes derived from benzimidazole (BH1–3 and …

Zinc (Zn) is a vital element. It plays indispensable roles in multifarious cellular processes,
affecting the expression and activity of a variety of molecules, including transcription factors …

The UV-and sensor-induced interferences to living systems pose a barrier for in vivo Zn2+
imaging. In this work, an intramolecular charge transfer (ICT) fluorophore of smaller aromatic …
