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.

We report a novel one‐second strategy for the surface treatment of conventional graphite electrodes for the electrochemical detection of valrubicin, a potent chemotherapeutic agent used intravesically for the treatment of bladder cancer. The surface graphenization process enhances the surface area of the electrode and introduces surface defects and strain that increase its electrocatalytic activity and provides fast charge transfer pathways for an efficient redox process with excellent stability due to the direct connection with the core graphite electrode. The surface graphenized electrode is characterized using electron microscopy and Raman spectroscopy, and its electrochemical properties are studied using cyclic voltammetry and electrochemical impedance spectroscopy. A voltammetric method is developed for valrubicin detection using the surface graphenized electrode, optimized, and the electrochemical reduction mechanism is elucidated. A calibration curve is established with a wide linear range of 0.02–3 μM and a low limit of detection of 26.9 nM. Excellent reproducibility and stability are displayed and the clinical validity is demonstrated by analyzing valrubicin in human serum, achieving a high recovery of ≈90 %. The high performance and excellent sensitivity of the developed electrode show the significant impact of the surface graphenization strategy for further application in electrochemical sensing.
