Anal Bioanal Chem 2023:10.1007/s00216-023-04768-7. [PMID: 37286905 DOI: 10.1007/s00216-023-04768-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 04/22/2023] [Accepted: 05/18/2023] [Indexed: 06/09/2023]
Abstract
Herein, we fabricated blue-fluorescence carbon quantum dots modified by ionic liquids (ILs-CQDs) with a quantum yield of 18.13% by employing orange peel as a carbon source and [BMIM][H2PO4] as a dopant. The fluorescence intensities (FIs) of ILs-CQDs were significantly quenched upon the addition of MnO4- with excellent selectivity and sensitivity in waters, and this phenomenon provided a feasibility for constructing a sensitive "ON-OFF" fluoroprobe. The prominent overlapping between the maximum excitation/emission of ILs-CQDs and the UV-Vis absorption of MnO4- implied an inner filter effect (IFE). The higher Kq value demonstrated that the fluorescence-quenching phenomenon was a static-quenching process (SQE). Coordination between MnO4- and oxygen/amino-rich groups in ILs-CQDs resulted in the alteration of zeta potential in the fluorescence system. Consequently, the interactions between MnO4- and ILs-CQDs belong to a joint mechanism of IFE and SQE. When plotting the FIs of ILs-CQDs vs. the concentrations of MnO4-, a satisfactorily linear correlation was obtained across the range of 0.3-100 μM with a detectable limit of 0.09 μM. This fluoroprobe was successfully applied to detect MnO4- in environmental waters with satisfactory recoveries of 98.05-103.75% and relative standard deviations (RSDs) of 1.57-2.68%. Also, it gave more excellent performance metrics as compared to the Chinese standard indirect iodometry method and other previous approaches for MnO4- assay. Overall, these findings offer a new avenue to engineer/develop a highly efficient fluoroprobe based on the combination of ILs and biomass-derived CQDs for the rapid/sensitive detection of metal ions in environmental waters.

In situ self-assembled cationic lanthanide metal organic framework membrane sensor for effective MnO 4- and ascorbic acid detection. Anal Chim Acta 2020; 1142:211-220.

Abstract
Developing portable membrane sensors to accurately detect the biomolecule ascorbic acid (AA) is extremely important for food safety and human health. Herein, we successfully design and synthesize a novel cationic metal organic framework (Eu-pbmc, Hpbmc = 2-(pyridine-2-yl)-1H-benzimidazole-5-carboxylic acid) and assemble polyacrylonitrile/Eu-pbmc membrane (PEM) by an in-situ growth strategy. Benefiting from the appreciable loading of Eu-pbmc nanoparticles and high water permeation flux, PEM possesses effective detection for MnO4- with a limit of detection (LOD) of 17 nM. Utilizing the cationic porous framework, we load MnO4- into PEM and construct a "on-off-on" system for effective AA detection. The oxidative MnO4- can be reduced by AA and the resulting turn-on luminescence can reflect the concentration of AA. Compared with pure Eu-pbmc crystals, PEM exhibits improved AA detection performance with LOD of 48 nM and detection time of 1 min via a concise detection operation. The stable membrane sensor realizes an accurate detection in real biological samples, meeting the practical requirement. Moreover, an IMP logic gate is helpful to analyze MnO4- and AA in water. The proposed novel luminescence platform as well as reasonable "on-off-on" luminescence mode provide a promising method for AA detection.

Abstract
Almost all existing methods for preparing reduced graphene oxide/Mn3O4 (RGO/Mn3O4) composites are based on the synthetized graphene or graphene oxides (GO), which make them complicated and high-cost processes. Here, we reported a new method, which is able to convert graphite directly to RGO/Mn3O4 composites. Thus, it is simpler, more economical, and productive. The structure of RGO/Mn3O4 inheriting intermediate product GO/MnO2 composites that are formed by the present method is a novel three-dimensional "multilayer steamed bread" nanostructure, which constitutes mutually beneficial "symbiosis". The nano-Mn3O4 supports the space between RGO layers and further to the combination of RGO to self-assemble into large-sized (>40 μm) nanocomposites. Meanwhile, the formed Mn3O4 particles were small (60 × 10 nm2) in diameter and distributed homogeneously without the use of any template and surfactant. Because the structure and nanosize of composite cause the excellent electrochemical properties, RGO/Mn3O4 electrodes deliver an enhanced specific capacitance of 438.7 F/g at 0.3 A/g and outstanding cyclic stability (77.5% of its initial capacitance is retained after 1000 cycles).

Abstract
Effective detection of organic/inorganic pollutants, such as antibiotics, nitro-compounds, excessive Fe3+ and MnO4 - , is crucial for human health and environmental protection. Here, a new terbium(III)-organic framework, namely [Tb(TATAB)(H2 O)]⋅2H2 O (Tb-MOF, H3 TATAB=4,4',4''-s-triazine-1,3,5-triyltri-m-aminobenzoic acid), was assembled and characterized. The Tb-MOF exhibits a water-stable 3D bnn framework. Due to the existence of competitive absorption, Tb-MOF has a high selectivity for detecting Fe3+ , MnO4 - , 4-nirophenol and nitroimidazole (ronidazole, metronidazole, dimetridazole, ornidazole) in aqueous through luminescent quenching. The results suggest that Tb-MOF is a simple and reliable reagent with multiple sensor responses in practical applications. To the best of our knowledge, this work represents the first TbIII -based MOF as an efficient fluorescent sensor for detecting metal ions, inorganic anions, nitro-compounds, and antibiotics simultaneously.
