“…Consequently, the incorporation of such polymers enhances the sensitivity of the electrodes, thereby amplifying their detection capabilities. [60,61] A case in point is the work of Olga I. Lipskikh et al in 2020, wherein they devised a voltammetric approach for determining TZ. They employed a composite electrode comprising carbon black and polyethylene (CBPCE), further modified its surface using a carbon ink (CI).…”

There are plenty of evidence that consuming high levels of azo dyes, such as Tartrazine, Sunset Yellow, Allura Red, Ponceau 4R, Amaranth, Sudan, and Azorubine, is associated with serious health problems. Therefore, electrochemical sensors have been developed for their effective detection, also offering low cost, portability, and the fact that they do not require harmful solvents. They are customarily employed in several electrochemical techniques, including cyclic voltammetry, differential pulse voltammetry, and square wave voltammetry. The most commonly employed materials in the manufacturing of electrochemical sensors are carbonaceous materials given their high stability, surface area, and conductivity. Employing these carbonaceous materials results in an enhanced sensitivity of electrochemical sensors when detecting azo dyes. To further improve the sensors, these materials are modified with metal oxides, polymers, polysaccharide, ionic liquids, and metal nanoparticles, allowing the detection of ultra‐sensitive traces of azo dyes. Therefore, this review provides an overview of the characteristics of modified carbonaceous materials and their applications for the detection of food azo dyes, along with a summary of the currently employed electroanalytical detection methods. Additionally, this review discusses the development of novel nanomaterials and their technological advances, while exploring their potential environmental and health impacts within the food industry.

“…Nevertheless, much research has elucidated that CV and its metabolites, which are nonbiodegradable through natural processes, embody the undesirable properties of carcinogenic, teratogenic, and mutagenic effects on organisms, causing the persistent issue of severe contamination in aquaculture and thus being inventoried as a contraindication in aquaculture by many countries [3–5]. At present, various methods were developed for determining CV, such as high performance liquid chromatography (HPLC) [6], ultrahigh performance liquid chromatography‐mass spectrometry (UPLC‐MS/MS) [7], enzyme linked immunosorbent assay (ELISA) [8], and electrochemistry methods [9], which were shown in Table 1. While chromatography relies on large and precise instruments, the ELISA method is costly, and electrochemical methods have poor stability and reproducibility.…”

To establish a new method for detecting crystal violet (CV), a harmful dye, herein, a genre of novel biomass carbon dots (CDs) was synthesized via a microwave method and employed as a fluorescent probe, in which water spinach and polyethylene glycol (PEG) performed as raw materials. Based on the inner filter effect (IFE) between the luminescent CDs and CV, the blue emission of this probe at 430 nm could be quenched by CV. Hence, a new strategy was proposed to selectively determine CV in aquaculture ambient. Moreover, under the optimal experiment conditions, this method showed a good linearity between the concentration of CV (c) and fluorescence quenching rate (ΔF/F0) in the concentration range of 4–200 μmol/L with the corresponding correlation coefficient (r) and the detection limit of 0.997 and 710 nmol/L, respectively. With advantages of environmental protectivity, sensitivity, affordability, and user‐friendliness, the facilely fabricated CDs could be successfully applied in detecting CV in aquaculture samples, providing a technical foundation for monitoring the pollution of CV and ensuring the quality and safety of aquatic products.
