Recent advances in Fluorescent-based cation sensors for biomedical applications

Subphthalocyanines as fluorescence sensors for metal cations

“…The details of these switching mechanisms may be found in many reviews. [3][4][5] For the recognition of alkali and alkaline earth metal cations, crowns are probably the most suitable hosts, since their selectivity and sensitivity of recognition may be easily tuned by their size, exchange of oxygen for other heteroatoms or attachment of additional binding sites either in the form of a supporting ligand or as a cryptand. [6][7][8][9][10] Wide diversity may be on the other hand found in signalling moieties, since many structurally different fluorophores can be found in the literature.…”

Multicomponent Reaction Based Tolyl-substituted and Pyrene-Pyridine Conjugated Isomeric Ratiometric Fluorescent Probes: A Comparative Investigation of Photophysical and Hg(II)-Sensing Behaviors

“…The design and development of novel uorescent probes for sensing of heavy metal ions have been attracted the attention of larger research communities due to their potential applications in analytical chemistry, clinical biochemistry, medicinal chemistry and environmental science [32,33]. The uorescent chemosensors have great demand due to their important features, which involves ease of operation, high sensitivity and selectivity, quick response, low-cost testing and compatibility for on-spot investigation [34].…”
