“…However, the lack of Cr(III) may cause dysglycemia and coronary arteriosclerosis, which increase the risk of diabetes and cardiovascular diseases. [41][42][43] In addition, Cr(III) and Cr(VI) can transform into each other under certain conditions, and Cr(VI) and its compounds are toxic. Therefore, it is of great signi¯cance to detect Cr(III) for human safety, environmental monitoring and life science research.…”

In this work, a solely gravity and capillary force-driven°ow chemiluminescence (GCF-CL) paper-based micro°uidic device has been proved for the¯rst time as a new platform for inexpensive, usable, minimally-instrumented dynamic chemiluminescence (CL) detection of chromium (III) [Cr(III)], where an appropriate angle of inclination between the loading and detection zones on the paper produces a rapid°ow of CL prompt solution through the paper channel. For this study, we use a cost-e®ective paper device that is manufactured by a simple wax screen-printing method, while the signal generated from the Cr(III)-catalyzed oxidation of luminol by H 2 O 2 is recorded by a low-cost and luggable CCD camera. A series of GCF-CL a®ecting factors have been evaluated carefully. At optimal conditions, two linear relationships between GCF-CL intensities and the logarithms of Cr(III) concentrations are obtained in the concentration ranges of 0.025-35 mg/L and 50-500 mg/L separately, with the detection limit of 0.0245 mg/L for a less than 30 s assay, and relative standard deviations (RSDs) of 3.8%, 4.5% and 2.3% for 0.75, 5 and 50 mg/L of Cr(III) (n ¼ 8). The above results indicate that the GCF-CL paper-based micro°uidic device possesses a receivable sensitivity, dynamic range, storage stability and reproducibility. Finally, the developed GCF-CL is utilized for Cr(III) detection in real water samples.

“…[1][2][3][4] In recent decades, novel uorescence chemosensors for metal ions, such as chromium, zinc, aluminum and copper, have gained importance due to their operational simplicity, high selectivity, sensitivity and rapidity. [5][6][7][8] Although the uorescence intensity of chemosensors quenched in the presence of Cr(III) has been reported, few papers are available on the uorescence enhancement of chemosensors with Cr(III) ions. [9][10][11][12][13][14] Among uorescent chemosensors, Bodipy sensors have been extensively studied for numerous applications (optic, sensor and dye) to a number of functional materials owing to their unique photophysical properties, such as sharp absorption prole, high uorescence quantum yields, good photo-stability and large extinction coefficients.…”

Bodipy-DPy) was designed as an efficient fluorescent chemosensor for Cr(III). The structure of Bodipy-DPy was confirmed by UV-vis spectroscopy, fluorometry, melting point analysis, 1 H-NMR, 13 C-NMR, elemental analysis and ESI-TOF-MS. Its photophysical properties was investigated by absorption, emission and excitation techniques. Based on chelation assisted fluorescence enhancement, a fluorometric method was developed for trace level detection, selectivity and concentration studies of chromium(III) in EtOH-H 2 O. The fluorescent ligand behaved as a chemosensor for Cr(III) cations and showed a strong red fluorescence upon coordination with Cr(III), whereas almost no fluorescence was observed for the other metal cations studied. The Bodipy-DPy has absorption and emission maxima at 528 nm and 535 nm, respectively. The equilibrium binding constant of Bodipy-DPy with Cr(III) was calculated as 1.17 Â 10 6 from the Stern-Volmer equation. Experimental Material and instrumentsBodipy and Bodipy-DPy were prepared according to the known procedures under an atmosphere of nitrogen 24 and puried by column chromatography. Purications were performed on column silica gel (Acros, silica gel 60, 32-70 mesh). Thin layer chromatography (TLC) was used on Silica gel plates (Merck, Kieselgel 60, 0.25 mm thickness) with long-wavelength light (365 nm). The deuterated chloroform for NMR spectroscopy

“…[13][14][15] Great efforts have also been made on designing turn-on sensors because turn-off sensors tend to produce a low signal output upon binding and are therefore prone to interfere with the temporal separation of similar complexes with timeresolved uorometry. [16][17][18][19] Unfortunately, most turn-on chemosensors for detection of Cr 3+ have focused on rhodamine derivatives, which can probe Cr 3+ by conversion of the non-uorescent rhodamine spirolactam to the highly uorescent ring-open amide form upon binding. [20][21][22][23][24][25] Furthermore, the long equilibrium time and high limits of detection of rhodamine derivatives do not satisfy the requirement of fast-response and high sensitivity under pharmacological conditions.…”

A fast-response, fluorescent ‘turn-on’ chemosensor for selective detection of Cr³⁺

et al. 2015

View full text Add to dashboard Cite

A fast-response, highly selective and sensitive chemosensor, 3, for Cr 3+ detection with turn-on fluorescence behavior in the physiological pH range was designed and synthesized. The chemosensor contained a combined push-pull system in which the fluorescent phenanthro[9,10-d]oxazole moiety acts as both the electron donor and a potential binding site. An electron deficient nitrile group served as the electron acceptor. A significant enhancement of fluorescene emission intensities was observed with increasing Cr 3+ concentration upon excition at 300 nm. The emission intensity reached its maximum on adding 8 equiv. of Cr 3+ where the quantum yield of 3-Cr 3+ was found to be 0.917, ca. 7-fold larger than the chemosensor 3.The selectivity mechanism of 3 for Cr 3+ was found to be based on the combined effects of the inhibition of ICT and CHEF. Remarkably the entire process was virtually complete in only 10 seconds, with a minimum detection limit for Cr 3+ of 1.72 × 10 -8 M -1 .
