Turn “on-off” fluorometric probe based on Sm3+ ions activated gold nanoclusters for tetracycline determination in food samples
A turn “on-off” fluorometric probe with good sensitivity and selectivity based on glutathione (GSH) fabricated gold nanoclusters (AuNCs) was developed for the determination of tetracycline (TC) in food samples in this work. Samarium ions (Sm3+) were used to aggregate the GSH-AuNCs by aggregation induced emission enhancement (AIEE), as a result fluorescence (FL) of GSH-AuNCs was turned on. The Sm3+ induced AIEE of AuNCs have eco-friendly and “green synthesis” features. Using TC, the FL of GSH-AuNCs-Sm3+ was turned off due to the strong interaction between Sm3+ and TC through dynamic quenching. The reasonable quantum yield (Q.Y) of GSH-AuNCs obtained using AIEE of Sm3+ ions was 5.3 %. The linear range of this probe was 1 – 20 µM with the lowest limit of detection (LOD) of 0.33 µM. This probe showed recoveries of 90.4–105 % in honey and milk samples. The GSH-AuNCs-Sm3+ is a good choice for sensing hazards in food products.
期刊介绍:
The Journal of Food Composition and Analysis publishes manuscripts on scientific aspects of data on the chemical composition of human foods, with particular emphasis on actual data on composition of foods; analytical methods; studies on the manipulation, storage, distribution and use of food composition data; and studies on the statistics, use and distribution of such data and data systems. The Journal''s basis is nutrient composition, with increasing emphasis on bioactive non-nutrient and anti-nutrient components. Papers must provide sufficient description of the food samples, analytical methods, quality control procedures and statistical treatments of the data to permit the end users of the food composition data to evaluate the appropriateness of such data in their projects.
The Journal does not publish papers on: microbiological compounds; sensory quality; aromatics/volatiles in food and wine; essential oils; organoleptic characteristics of food; physical properties; or clinical papers and pharmacology-related papers.
