Special Issue Information

Dear Colleagues,

Biogenic amines (BAs) are biomolecules, mostly known for their toxic and carcinogenic effects. Commonly, they are used as an indicator of quality preservation in food and beverages since their presence in higher concentrations is associated with poor quality.

The purpose of this Special Issue is to improve understanding around methodologies and new development technologies used for the detection and quantification of BAs in fresh and processed food matrixes as well as in beverages.

Analytical methods used for the quantification of BA are mainly based on chromatographic methods, thin layer chromatography, gas chromatography, capillary electrophoresis, and high-performance liquid chromatography. Biosensors have proven to be quite successful, as they are sensitive and robust devices providing a simple, economical, and fast alternative in the detection of BAs

Full papers, communications, and reviews are welcome. Reviews must offer a critical overview of the state-of-the-art on fundamentals, technologies, and applications.

In this sense, we encourage the submission of manuscripts dedicated to the detection of BAs. Topics include, but are not limited, to the following:

  • Analytical determinations;
  • Gas chromatography;
  • High-performance liquid chromatography;
  • Biosensors;
  • Fibre-optic sensing configurations;
  • UV, VIS, and NIR spectroscopy;
  • Electrochemical sensors;
  • Colorimetric approaches.

Chlorpyrifos is an organophosphorus insecticide, which can be used to control a variety of chewing and piercing mouthparts pests in agricultural production. It can destroy the normal nerve impulse conduction by inhibiting the activity of acetylcholinesterase or cholinesterase in the nerves, causing a series of poisoning symptoms. In order to achieve the quantitative analysis of chlorpyrifos residues in agricultural products, an aptamer-controlled signal molecule release method was developed in this study. The signal molecule 4-ATP of surface-enhanced Raman spectroscopy (SERS) was loaded into aminated mesoporous silica nanoparticles (MSNs-NH2) prepared by the one pot method, and then coated with an aptamer of chlorpyrifos through electrostatic interaction. The specific binding of the aptamer and chlorpyrifos led to the release of 4-ATP, and the amount of 4-ATP released was positively correlated with the amount of chlorpyrifos. Finally, the standard curve of chlorpyrifos quantitative detection based on SERS was established. Meanwhile, Ag-carrying mesoporous silica ([email protected]) was prepared as the reinforcement substrate for SERS detection. The results showed that there was a good linear correlation between the Raman intensity and the concentration of chlorpyrifos at 25–250 ng/mL, and the limit of detection (LOD) was 19.87 ng/mL. The recoveries of chlorpyrifos in the apple and tomato samples were 90.08–102.2%, with RSD < 3.32%. This method has high sensitivity, specificity, reproducibility and stability, and can be used for the quantitative detection of chlorpyrifos in the environment and agricultural products. Full article
