“…These peaks approximately correspond to those reported for the TMA-A zeolites synthesized using hydrothermal methods. 18 Further treatment of the H 2 O 2 -treated natural zeolite with a solution of gold ions, followed by reduction using C. inophyllum L. leaf extract, produced more regularly shape particles, as shown in Fig. 3(c).…”

A green method of coating natural zeolite with metallic gold, and characterizing the resulting products was developed. The product was obtained by dispersion of natural zeolite powder in HAuCl 4 solution, followed by reduction of the Au 3+ ions using Callophyllum inophyllum L. leaves extract and subsequently calcined at 300 °C. The characterization results show that element mapping using EDX did not definitively prove the presence of gold in the zeolite. However, the XRD results did suggest that metallic gold was present in the corresponding product.

“…The resulting biosensor was successfully applied for the determination of PUT in tiger prawn samples. Chauhan et al (2017) utilized a polyamine oxidase (PAO), immobilized by glutaraldehyde crosslinking on a hybrid constituted of gold nanoparticles and zeolites nanocrystals, for the determination of SPD levels in carp (Labeo) samples. Saghatforoush et al (2014) demonstrated the feasibility of an enzymeless sensor based on β-cyclodextrins and graphene oxide immobilized on a glassy carbon electrode, and successfully applied the sensor for the determination of CAD in fish samples.…”

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.
