Rapid fluorescence spectroscopic screening method for the sensitive detection of thiabendazole in red wine

Abstract

This method (d) has the advantage of improving spectral resolution and measurement sensitivity, as well as eliminating the interference of spectral background from red wine, compared with UV-Vis absorption spectroscopy (a) and conventional fluorescence spectroscopy (b).

Fluorescence enhancement of fungicide thiabendazole by van der Waals interaction with transition metal dichalcogenide nanosheets for highly specific sensors

“…The proposed methodology allows TBZ analysis at the nM level showing a detection limit (3σ b /slope) of 2.7 nM. This detection limit is similar to or even better than others previously reported for TBZ determination using either luminescence techniques including room-temperature phosphorescence (RTP), electrochemical methods or more sophisticated procedures such as liquid chromatography and capillary electrophoresis (see Table S1 22,23,[39][40][41][42][43][44][45][46][47] in the ESI †).…”

Utilizing a Rapid Multi-Plug Filtration Cleanup Method for 72 Pesticide Residues in Grape Wines Followed by Detection with Gas Chromatography Tandem Mass Spectrometry

“…The analysis of pesticide residues in wine is challenging due to the complexity of the matrix, which contains alcohol, organic acids, sugars and polyphenols (e.g., anthocyanins, flavonols and tannins). Many effective preparation methods of wine samples have been reported, including liquid-liquid extraction (LLE) with different organic solvents [11,[18][19][20], solid-phase extraction (SPE) with reversed-phase C18 or polymeric sorbents [21][22][23][24][25][26][27], solid-phase microextraction (SPME) [22,28,29] and ultrasound-assisted emulsification microextraction (USAEME) [28,30], single drop liquid-liquid microextraction (LLME) [31][32][33][34], membrane-assisted solvent extraction [4] and dispersive liquid-liquid microextraction (DLLME) [35][36][37].…”

Benzimidazole and imidazole fungicide analysis in grape and wine samples using a competitive enzyme-linked immunosorbent assay

“…Although this method enabled simultaneous determination of the three fungicides, the limits of detection and quantication are not low enough compared with those of other methods. Moreover, Zhong et al 33 validated a rapid uorescence spectroscopic screening method for the sensitive detection of thiabendazole in red wine. Compared with UV-vis absorption spectroscopy and conventional uorescence spectroscopy, this method has the advantages of improving spectral resolution and avoiding the requirement for complicated purication and pretreatment procedures.…”
