Abstract
As the "mother of antioxidants", glutathione (GSH) plays an important role in physiological functions. Rapid and accurate monitoring of GSH is of great significance for medicinal chemistry, food chemistry, and clinical medicine. We herein report a visual ratiometric fluorescence sensor based on MnO2 nanowires (MnO2 NWs) as an oxidant, quencher and recognition unit for the determination of GSH. The powerful ratiometric fluorescent probe was constructed by mixing thiamine (VB1) and rhodamine B (RhB) with the help of MnO2 NWs. MnO2 NWs could not only effectively quench the fluorescence of RhB due to the inner filter effect (IFE), but also oxidized non-fluorescent VB1 to blue fluorescent thiochrome (oxVB1). Upon interaction with GSH, the quenched RhB fluorescence could be rapidly restored through decomposition of MnO2 NWs into Mn2+, while the oxVB1 fluorescence decreased, showing an apparent color change from blue to red. The concentration of GSH was proportional to the ratio of fluorescence intensities of RhB and oxVB1, and the detection linear range was 1 to 10 000 μM with comparable selectivity. This ratio fluorescence sensor was successfully applied to GSH determination in whitening capsules and glutathione tablets with satisfactory results, and the sensor may be a potentially powerful tool for the detection of GSH.

LUMINESCENCE 2020; 36:110-116. [PMID: 32725690 DOI: 10.1002/bio.3927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 07/17/2020] [Accepted: 07/24/2020] [Indexed: 11/10/2022]
Abstract
Many sulfides are toxic substances that easily harm the respiratory tract, therefore affecting respiratory function or damaging other organs of the body, leading to its failure. Therefore, there is a pressing need to develop methods for sensitive detection of sulfur ions (S2- ). Based on luminescence resonance energy transfer (LRET) theory, we report the construction of a near-infrared (NIR) excitation luminescence probe using NaGdF4 :Yb3+ ,Er3+ @NaYF4 upconversion nanoparticles (UCNPs) as the donor and dye-670 as the receptor for detection of S2- . When UCNPs and dye-670 molecules were combined using ligand exchange and electrostatic attraction, LRET occurred and UCNP luminescence was quenched. When S2- was added to the system, sulfide ions were able to destroy the double bond of the dye, inhibiting LRET and restoring UCNP luminescence. Under optimum condition, the linear range of S2- detection was 0.65-18.2 μM, and the detection limit was 34.2 nM. This method was applied for determination of S2- in water with satisfactory results.

A dual (colorimetric and fluorometric) detection scheme for glutathione and silver (I) based on the oxidase mimicking activity of MnO 2 nanosheets. Mikrochim Acta 2019; 186:498. [PMID: 31270601 DOI: 10.1007/s00604-019-3613-4] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Accepted: 06/14/2019] [Indexed: 02/01/2023]
Abstract
A fluorimetric and colorimetric method is described for the determination of glutathione (GSH) and silver (I). It is based on the use of MnO2 nanosheets that were prepared by solution mixing and exfoliation. They display oxidase-mimicking activity and can catalyze the oxidation of o-phenylenediamine (OPD) to form yellow 2,3-diaminophenazine (DAP) with an absorption maximum at 410 nm. DAP also has a yellow fluorescence (with a peak at 560 nm). The MnO2 nanosheets can be rapidly reduced to Mn2+ by GSH. This reduces the efficiency of the oxidase mimic MnO2 and causes a decrease in fluorescence and absorbance intensity. However, on addition of Ag+, a complex is formed with GSH. It prevents the destruction of MnO2 nanosheets so that the enzyme mimicking activity is retained. A dual-method for the determination of GSH and Ag(I) was developed. It has excellent sensitivity for GSH with lower detection limits of 62 nM (fluorimetric) and 0.94 μM (colorimetric). The respective data for Ag(I) are 70 nM and 1.15 μM. The assay was successfully applied to the determination of GSH and Ag(I) in spiked serum samples. Graphical abstract Schematic presentation of a method for colorimetric and fluorometric determination of glutathione (GSH) and silver(I). MnO2 nanosheets are reduced to Mn(II) by GSH. This reduces the enzyme-mimicking activity of MnO2 nanosheets and causes a decrease in fluorescence and absorbance. On addition of Ag(I), the enzyme-like activity is increasingly retained. A decrease in fluorescence and absorbance is not observed any longer.
