“…Here, a suitable redox probe’s electrochemical oxidation or reduction was observed in a test solution over a template-extracted and template-bound MIP film [ 167 ]. For the redox probe hexacyanoferrate, the cyclic voltammograms in the presence of a template molecule differed from those in its absence at the MIP-modified electrode ( Figure 12 ) [ 7 , 167 , 168 , 169 , 170 ]. The mechanism, known as the “gate effect”, was first described by Yoshimi et al [ 168 ] on an acrylic MIP-based chemosensor.…”

Rapid, selective, and cost-effective detection and determination of clinically relevant biomolecule analytes for a better understanding of biological and physiological functions are becoming increasingly prominent. In this regard, biosensors represent a powerful tool to meet these requirements. Recent decades have seen biosensors gaining popularity due to their ability to design sensor platforms that are selective to determine target analytes. Naturally generated receptor units have a high affinity for their targets, which provides the selectivity of a device. However, such receptors are subject to instability under harsh environmental conditions and have consequently low durability. By applying principles of supramolecular chemistry, molecularly imprinted polymers (MIPs) can successfully replace natural receptors to circumvent these shortcomings. This review summarizes the recent achievements and analytical applications of electrosynthesized MIPs, in particular, for the detection of protein-based biomarkers. The scope of this review also includes the background behind electrochemical readouts and the origin of the gate effect in MIP-based biosensors.

“…It was later found that analyte binding can also suppress the intensity of the faradaic probe current. Such hindered or enhanced diffusion arises from the changes in the thickness and topography of the MIP-bound film [ 167 , 169 , 170 ].…”

“…In this respect, the presence and concentrations of tyramine detected in the samples are considered to be significant. In this respect, recent studies have focused in the fast and effective methods for the determination of tyramine in various foods (Ayerdurai et al, 2021;Draz et al, 2021). However, the current processing and handling stage conditions of Konya Green cheese should be further improved via hygienic measures indicated by several researchers (Costa et al, 2018;Papageorgiou et al, 2018;Renes et al, 2014).…”

The physicochemical properties, color characteristics, and biogenic amine (BA) concentrations of Konya Green cheese during ripening process with mold were investigated.Four productions were made in different periods, and the samples were analyzed at the end of the cold storage period (0) and on days 1, 3, 7, 15, 21, 24, and 30 of mold ripening. It was found that dry matter, acidity, and salt values tend to increase, whereas pH and a w values tend to decrease during the mold ripening period in all production groups.Total BA content increased significantly from 70.91 to 136.95 mg/kg during the ripening period (p < .01). Principal components explained 92.5% of the total variation among the four production group cheese. Based on the Hierarchical clustering analysis, three clusters were obtained: 1st (0, 3, 15), 2nd (1, 24, 30), and 3rd (7, 21). Tyramine, cadaverine, putrescine, and histamine were observed in 2nd cluster as per the PCA. Novelty impact statementThe biogenic amine formation and dominancy of the principal biogenic amins through ripening period of Konya Green cheese were determined using RP-HPLC. The predominant biogenic amines determined at the end of the ripening time were tyramine, cadaverine, and putrescine which represent around 81% of the total BA present. To the best of our knowledge, this is the first study for determinig the biogenic amin production of Konya Green cheese. How to cite this article: Telli N, Topkafa M.

“…It was thus found that the presence of monoamine oxidase enzyme can efficaciously metabolized tyramine. However, the intake of MAOI drugs inhibited the action of such enzymes and thus may cause severe hypertensive crisis . Moreover, due to its production from the mentioned food source, this biogenic amine was named after the Greek word “tyros” which means “cheese”. , The excessive intake of this food hazard can cause peripheral vasoconstriction, elevated blood glucose level, release of norepinephrine, palpitations, cold sweats, and even death in severe cases.…”

“…Nevertheless, most of the mentioned techniques demand extensive sample preparation measures, expensive instrumentation, excessive amounts of high-priced chemicals, numerous extraction steps, and experienced operators. In contrast to the conventional analytical methodologies, the electrochemical technique is gaining immense popularity owing to its robustness, high sensitivity, selectivity, user friendly instrumentation, on the spot real sample analysis, as well as precise sample analysis time . It has been found that although the conventional unmodified carbon electrode can be used as a site for electrochemical tyramine oxidation, such methodology may suffer from the lack of sensitivity and poor limit of detection (LOD) because of the lower produced currents.…”

The presented study outlines the fabrication of chitosan (CS)-loaded lanthanum iron oxide (LFO) nanoparticles (CS/LFO) via a simple auto-combustion method combined with ultrasonication. The various prepared x CS/LFOs (x = 100, 200, 300, 400, and 500) were well analyzed with several characterization techniques. The x CS/LFO-modified glassy carbon electrode (GCE) was then utilized for electrochemical tyramine detection. Additionally, the obtained electrochemical response was also compared with the pure constituents. Herein, the numerous electrochemical parameters including the volume of electrocatalyst loaded, pH of solution, and accumulation time were optimized so as to acquire the efficient detection. Under optimum conditions, the 400 CS/LFO-modified GCE exhibited an impressive electrochemical response for tyramine detection. The proposed electrochemical sensor afforded a linear co-relation between the anodic peak current and concentration of tyramine in the range of 0.02–100 μM with the detection limits of 0.6158 μM or 615.8 nM (by the linear sweep voltammetry method) and 0.5814 μM or 581.4 nM (by the differential pulse voltammetry method). Furthermore, the prepared 400 CS/LFO was applied on the screen-printed electrode and its stability was evaluated for a period of 30 days in order to develop a portable electrochemical sensor. The constructed sensor displayed promising stability, repeatability, and reproducibility for tyramine detection. The real-time analysis capability of the introduced sensing platform was evaluated via real sample analysis of various food products including milk, beer, fish, meat, and yoghurt. The prepared sensor afforded desirable recovery rates, demonstrating its practical utility.
