“…Fluorescence has become an indispensable tool for the quantitative analysis of bioanalytes, owing to its rapid, noninvasive, and sensitive response behavior. − Several attempts have been made over the years to achieve efficient protein sensing − based on fluorescence technology. However, lack of selectivity, very little change in spectral output, insufficient detection limits, and high background-noise signals limited the use of these probes in biodiagnostics as well as in live-cell imaging.…”

Two cyanine-based fluorescent probes, ( E)-2-(4-(diethylamino)-2-hydroxystyryl)-3-ethyl-1,1-dimethyl-1 H-benzo[ e]indol-3-ium iodide (L) and ( E)-3-ethyl-1,1-dimethyl-2-(4-nitrostyryl)-1 H-benzo[ e]indol-3-ium iodide (L), have been designed and synthesized. Of these two probes, the twisted-intramolecular-charge-transfer (TICT)-based probe, L, can preferentially self-assemble to form nanoaggregates. L displayed a selective turn-on fluorescence response toward human and bovine serum albumin (HSA and BSA) in ∼100% aqueous PBS medium, which is noticeable with the naked eye, whereas L failed to sense these albumin proteins. The selective turn-on fluorescence response of L toward HSA and BSA can be attributed to the selective binding of probe L with HSA and BSA without its interfering with known drug-binding sites. The specific binding of L with HSA led to the disassembly of the self-assembled nanoaggregates of L, which was corroborated by dynamic-light-scattering (DLS) and transmission-electron-microscopy (TEM) analysis. Probe L has a limit of detection as low as ∼6.5 nM. The sensing aptitude of probe L to detect HSA in body fluid and an artificial-urine sample has been demonstrated.

Benzo five-/six-membered nitrogen-containing heterocyclic compound with a rigid plane and a large conjugate structure can emit characteristic fluorescence in a variety of organic solvents and mixed solutions, and N, O, S heteroatoms in the structure can serve as binding sites for fluorescent probes. Therefore, in recent years, benzo nitrogen-containing heterocyclic compounds are increasingly becoming one of the research focuses in the field of fluorescent probes. From the perspective of starting materials, synthesis methods, molecular structure, interaction mechanism, benzo five-/ six-membered nitrogen-containing heterocyclic fluorescent probes containing the structure of benzoxazole, benzothiazole, benzimidazole, indole, carbazole, quinoline, benzopyrazine and phenazine are introduced with emphasis. And their detection application for a variety of analytes, such small molecules, metal cations, anions and pH are reviewed. In the future, it is worthy of further attention to the research on the integration of multiple heterocyclic functional structures into a multifunctional fluorescent probe by simple and green synthesis.

“…8 Depending on substitutions, rhodamine derivatives were reported as chemosensors for multi-analyte sensors; particularly few of them are selective for trivalent cations of aluminum, chromium, and iron. [9][10][11][12] Recently, our group reported a rhodamine based chemosensor for the selective detection of Group 13 cations. 13 That was probably the rst report of a rhodamine based dye for the identication of Group 13 cations.…”
