A dual-emission fluorescence probe for simultaneous quantification of CN− and Cr2O72− ions based on modified g-C3N4

Preparation of a bis-Schiff base immobilized mesoporous SBA-15 nanosensor for the fluorogenic sensing and adsorption of Cu2+

“…For the evaluation of the practical applicability of the nanosensor, MS-NSP was tested for the determination of Cu 2+ in some local aqueous samples. 40 Initially, the water samples were filtered through a syringe filter to remove undissolved substances. After the addition of known amounts of Cu 2+ and adjustment of the solution pH value ( pH 6.0), the concentration of Cu 2+ was measured using the previous proposed method.…”

A Water-Soluble Naphthalimide-Based Fluorescent Probe for Specific Sensing of Fe3+ and $\text{C}{{\text{r}}_{2}}\text{O}_{7}^{2-}$

“…Further, similar spectral behaviors had been recorded in previously reported literatures. [25,27,32,35,[45][46][52][53] Cr O -, EDTA was added as chelating agent or auxiliary agent of Fe 3 ＋ to shield the fluorescence quenching caused by Fe 3 ＋ when the probe 1 was detecting Cr O -(Figure 8). It was obvious that EDTA hardly affected the fluorescence of probe 1 and the fluorescence of probe 1 recognizing Fe 3 ＋ or Therefore, EDTA can not be used as an auxiliary or chelating agent for probe 1 to distinguish Fe Cr Oand the reversibility of probe 1 assisted by EDTA…”

Lansoprazole-Based Colorimetric Chemosensor for Efficient Binding and Sensing of Carbonate Ion: Spectroscopy and DFT Studies

“…Herein, we proposed a naked-eye chemosensor, which has some superior as a simple process, biocompatibility, efficiency, side effects on the body, and rapid response time. As a part of our ongoing research on the design of chemosensors (Karimi et al, 2017 ; Shiravand et al, 2018 , 2020 ; Ahmadi et al, 2019 ; Arab et al, 2019 ; Kordi et al, 2019 ), we report the study of a chemosensor (L) for efficient sensing of carbonate ion over other ions by UV-Visible spectroscopy and remarkable colorimetric responses in the solution. The chemosensor L detected ion by an alteration in absorbance accompanied by an instantaneous color change from colorless to yellow.…”
