“…Numerous receptors have been successfully designed to detect biomolecules by hydrogen bonds [14,15]. However, water molecules typically compete with analytes for binding to receptors in aqueous solutions [16]. Hence, metal ions are regarded as an appropriate probe for forming complexes with biomolecules by electrostatic interaction and are suitable for bioanalysis of samples with high moisture content.…”

Gold nanoparticles (Au-NPs), with the dual sensor system of colorimetric and fluorescence responses, were developed for the determination of histamine as a spoilage monitor for distinguishing lifetime and freshness of aquatic products. Upon addition of histamine, the absorption coefficient orders of magnitude via the interaction of free electrons and photons were affected, and the characteristic absorption peak of Au-NPs was red-shifted from 520 nm to 664 nm. Meanwhile, the large amino groups in the networks of histamine-Au-NPs with high molecular orbital exhibited excellent fluorescence behavior at 415 nm. Au-NPs offered a range of 0.001–10.0 μM and 0.01–1.0 μM with a limit of detection of 0.87 nM and 2.04 nM by UV-vis and fluorescence spectrum assay, respectively. Moreover, Au-NPs could be used to semiquantitatively analyze histamine with the naked eye, since the significant colorimetric and fluorescence reaction of Au-NPs solution that coincided with different concentrations of histamine can be observed as the histamine concentration was 0.1–1.0 μM. Both of the dual-sensor systems of Au-NPs were successfully applied to the quantitative analysis of histamine in fresh salmon muscle, suggesting the simplicity and rapidity in the dual detection approaches of Au-NPs might be suitable for spoilage assay of aquatic food to ensure food safety.

Endogenous and food-derived polyamines: determination by electrochemical sensing

et al. 2018

Polyamines (PAs) are involved in a variety of fundamental physio-pathologic processes. The concentration of these polycations in organs and tissues depends on their endogenous production and oxidation rates, and on their intake from foods. Besides being largely accepted as markers for the progress of several pathologies, PAs may exert themselves different effects on humans, ranging from being positive to be drastically detrimental depending on the organism conditions. Thus, if the determination of polyamines content in tissue samples is of great importance as they could be indicators of several diseases, their quantification in food is fundamental for modulating the diet to respond to a specific human health status. Thus, the determination of PA content in food is increasingly urgent. Standard analytical methods for polyamine quantification are mainly based on chromatography, where high-performance liquid chromatography and gas chromatography are the most often used, involving pre-column or post-column derivatization techniques. Driven by the growing need for rapid in situ analyses, electrochemical biosensors, comprising various combinations of different enzymes or nanomaterials for the selective bio-recognition and detection, are emerging as competitors of standard detection systems. The present review is aimed at providing an up-to-date overview on the recent progresses in the development of sensors and biosensors for the detection of polyamines in human tissues and food samples. Basic principles of different electrochemical (bio)sensor formats are reported and the applications in human tissues and in foods was evidenced.

Nanozymes refer to nanomaterial‐based enzyme mimics. Most nanozyme assays use chromogenic molecules as substrates that can produce an absorbance change in the visible region upon reaction. For certain applications, such as imaging, fluorescence and luminescence signals are required. Fluorescence detection is also advantageous for sensor development due to its low background signal and high sensitivity. A few substrates, such as Amplex Red and luminol, allow luminescence generation with many oxidative nanozymes. In addition, these substrates can work at neutral pH, useful for intracellular applications. In this review, we summarize luminescence signalling‐based nanozyme systems. We begin with the properties of commonly used substrates. A few specific nanozymes are highlighted, including metal nanoparticles, metal oxide nanomaterials, carbon‐based nanomaterials, and metal–organic frameworks. Finally, a few future research opportunities are discussed.
