“…[16] One way to stabilize enzymes in physical adsorption is the addition of some additives. The complex three-dimensional structures of enzymes are stabilized by adding different additives, such as cations, [17] dyes, [18][19][20] drugs [21] and organic compounds [22] in the adsorption procedure. These additives enhanced the stabilities of enzymes, including thermostability, [23] chemical stability, [17] and acidic-basic stability.…”

A highly sensitive and selective electrochemical biosensor for catechol (CC) detection was developed by immobilizing tyrosinase (TYR) on a glassy carbon electrode (GCE) modified with sulfide minerals (SFMs) in the co‐adsorption of acridine orange (AO). The sensor employed natural SFMs as the substrate material and utilized AO as a molecular recognition probe to create synergy effect for TYR to detect catechol. The developed TYR/AO/SFMs/GCE biosensors were characterized by scanning electron microscope, energy dispersive analysis of X‐rays spectroscopy, X‐ray diffraction spectra, X‐ray fluorescence, and electrochemical analysis. The results show that the sensors have excellent electrochemical activity for the detection of catechol (CC) under optimized conditions. The linear ranges were 0.1–50 μM, 0.1–10 μM, 0.1–50 μM and 0.1–100 μM for galena, pyrite, chalcopyrite and sphalerite, respectively, with the detection limits of 1.18 μM, 0.29 μM, 0.54 μM and 0.68 μM, respectively. The sensors also have good reproducibility, stability, repeatability and anti‐interference ability. AO is essential to increase the adsorbed amount and provides suitable orientation of the adsorbed TYR on these sulfide minerals’ surfaces. In consideration of cost‐effective and rich resources of sulfide minerals, easily physical adsorption method, combination of organic dye, minerals and enzymes, this strategy paves a new way to design other novel electrochemical biosensors.

“…The reported REVO 4 -based electrode materials demonstrated enhanced electrochemical behaviors in respective analytes than other modified electrodes. In this aspect, the RMO 4 ternary oxides are a broad mixture of compounds whose unique features have been extensively researched. − Orthovanadates (M = V) are of particular interest to us, especially those containing a rare earth atom such as R . Sensors, scintillators, lasers, and photocatalytic materials are a few of the applications for these materials. − Because of their practical and theoretical relevance, REVO 4 rare-earth orthovanadates (where RE = trivalent rare-earth atom) are presently gaining much attention. − Many of these materials host materials for thermophosphors, nonlinear optics, optical devices, and luminescent emitters and are apt for real-time industrial applications due to their optical and luminescent properties.…”

Nanomaterials have versatile properties owing to their high surface-to-volume ratio and can thus be used in a variety of applications. This work focused on applying a facile hydrothermal strategy to prepare praseodymium vanadate nanoparticles due to the importance of nanoparticles in today's society and the fact that their synthesis might be a challenging endeavor. The structural and morphological characterizations were carried out to confirm the influence of the optimizations on the reaction's outcomes, which revealed praseodymium vanadate (PrVO 4 ) with a tetragonal crystal system. In this regard, the proposed development of electrochemical sensors based on the PrVO 4 nanocatalyst for the real-time detection of arsenic drug roxarsone (RXS) is a primary concern. The detection was measured by amperometric (i−t) signals where PrVO 4 /SPCE, as a new electrochemical sensing medium for RXS detection, increased the sensitivity of the sensor to about ∼2.5 folds compared to the previously reported ones. In the concentration range of 0.001−551.78 μM, the suggested PrVO 4 / SPCE sensor has a high sensitivity for RXS, with a detection limit of 0.4 nM. Furthermore, the impact of several selected potential interferences, operational stability (2000 s), and reproducibility measurements have no discernible effect on RXS sensing, making it the ideal sensing device feasible for technical analysis. The real-time analysis reveals the excellent efficiency and reliability of the prosed sensor toward RXS detection with favorable recovery ranges between ±97.00−99.66% for chicken, egg, water, and urine samples.

“…Hence, a considerable range of concentrations had to be covered for CT fabrication even at lower levels in the environmental samples. Numerous analytical methods have been established for the determination of CT, which include high-performance liquid chromatography, gas chromatography, flow-injection analysis, chemiluminescence, and electrochemical techniques. − Among these methods, electrochemical techniques are more prominent due to their cost-effectiveness, easy handling, and facile approach for the impulsive monitoring of environmental pollutants. − …”

Construction of a Copper Bismuthate/Graphene Nanocomposite for Electrochemical Detection of Catechol

et al. 2022

Binary metal oxides with carbon nanocomposites have received extensive attention as research hotspots in the electrochemistry field owing to their tunable properties and superior stability. This work illustrates the development of a facile sonochemical strategy for the synthesis of a copper bismuthate/graphene (GR) nanocomposite-modified screen-printed carbon electrode (CBO/GR/SPCE) for the electrochemical detection of catechol (CT). The formation of an as-prepared CBO/GR nanocomposite was comprehensively characterized. The electrochemical behavior of the CBO/GR/SPCE toward CT was investigated by voltammetry and amperometry techniques. The fabricated CBO/GR/SPCE manifests an excellent electrocatalytic performance toward CT with a lower peak potential and a higher current value compared to those of CBO/SPCE, GR/SPCE, and bare SPCE. It is attributed to enhanced electro-catalytic activity, synergetic effects, and good active sites of the CBO/GR nanocomposite. Under the electrochemical condition, the CBO/GR/SPCE displayed a wide linear sensing range, trace-level detection limit, acceptable sensitivity, and excellent selectivity. Furthermore, our proposed CBO/GR electrode was employed successfully for CT detection in water samples.
