A highly selective fluorescent chemodosimeter based on rhodamine is synthesized which undergoes Cu2+ driven hydrolysis in aqueous media to produce fluorescence turn-on changes with a detection limit up the nanomolar range.
The potential use of fluorescent molecular probes to measure ions and biomolecules has contributed incessantly the understanding chemical biological systems. approach many advantages such as high sensitivity, simplicity non-destructive cellular imaging that offer visible information about targeted species. In this article, our objective is discuss have sensing applications within mitochondrial environment. Mitochondria are organelles which well known for their unique physiological functions...
Presynaptic glutamate replenishment is fundamental to brain function. In high activity regimes, such as epileptic episodes, this process thought rely on the glutamate-glutamine cycle between neurons and astrocytes. However presence of an astroglial glutamine supply, well its functional relevance in vivo healthy remain controversial, partly due a lack tools that can directly examine transfer. Here, we generated fluorescent probe tracks live cells, which provides direct visual evidence...
Resonance energy transfer (RET) between donor-acceptor architecture is an important physical mechanism which used enormously for the development of fluorescent probes. The unique advantage RET its ability to non-radiatively molecules over biologically relevant distances. distance dependency makes this approach suitable bioanalysis such as distances biomolecules and molecular level interactions, both in vitro vivo. In addition, a proficient probes with ratiometric measurements. recent years,...

Abstract The development of highly selective sensors for potassium is great interest in biology. Two new hydrosoluble (Calix‐COU‐Alkyne and Calix‐COU‐Am) based on a calix[4]arene bis(crown‐6) an extended coumarin were synthesized characterized. photophysical properties complexation studies these compounds have been investigated show high molar extinction coefficients fluorescence quantum yields. Upon with the millimolar concentration range, increase one‐ two‐photon emission detected. A...
A new heteroditopic chemosensor based on the 1,3-alternate conformation of thiacalix[4]crown shows a ratiometric fluorescence response towards Hg(2+) ions. Further, negative allosteric behaviour between Hg(2+)/Li(+) ions is observed. Thus, metal ion exchange triggers switchable fluorescent chemosensor.
