“…To address the above-mentioned issues, much effort has been made to develop novel modified electrodes that are capable of efficiently detecting Allura Red based on the oxidation signals. Novel electrochemical sensors based on multiwalled carbon nanotube (MWCNT) [28,29], ionic liquids [30], cobalt oxide [31], and cobalt complex [32] modified electrodes have shown great potentials on the detection of Allura Red, due to their excellent accumulation efficiency and large specific surface area. For example, MWCNT/GCE showed a wide linear response range of 496-4468 µg/L, and it was applied to the analysis of commercial isotonic sports drinks with satisfactory results [28].…”

Titania/electro-reduced graphene oxide nanohybrids (TiO2/ErGO) were synthesized by the hydrolysis of titanium sulfate in graphene oxide suspension and in situ electrochemical reduction. It provides a facile and efficient method to obtain nanohybrids with TiO2 nanoparticles (TiO2 NPs) uniformly coated by graphene nanoflakes. TiO2/ErGO nanohybrids were characterized by transmission electron microscopy, X-ray diffraction, cyclic voltammogram, and electrochemical impedance spectroscopy in detail. Compared with pure ErGO and TiO2 NPs, TiO2/ErGO nanohybrids greatly enhanced the electrocatalytic activity and voltammetric response of Allura Red. In the concentration range of 0.5–5.0 μM, the anodic peak currents of Allura Red were linearly correlated to their concentrations. However, the linear relationship was changed to the semi-logarithmic relationship at a higher concentration region (5.0–800 μM). The detection limit (LOD) was 0.05 μM at a signal-to-noise ratio of 3. The superior sensing performances of the proposed sensor can be ascribed to the synergistic effect between TiO2 NPs and ErGO, which provides a favorable microenvironment for the electrochemical oxidation of Allura Red. The proposed TiO2/ErGO/GCE showed good reproducibility and stability both in determination and in storage, and it can accurately detect the concentration of Allura Red in milk drinks, providing an efficient platform for the sensitive determination of Allura Red with high reliability, simplicity, and rapidness.

“…When used excessively, synthetic dyes, especially those containing aromatic rings and azofunctional groups, become potentially toxic to the human body [ 1 , 2 ]. Decomposition products can accumulate and provoke allergic reactions, the development of cancer, and disorders of the gastrointestinal tract, respiratory tract, and central nervous system [ 3 ].…”

“…High electrocatalytic activity with regard to Ponceau 4R oxidation was demonstrated by an electrode based on a composite containing solid paraffin and an ionic liquid-modified expanded graphite paste electrode [ 1 ]. In comparison with unmodified electrodes, a 7.5-fold increase in the peak oxidation current of Ponceau 4R was observed on the ionic liquid-modified expanded graphite paste electrode, which can be explained by the sensitizing effect of the ionic liquid.…”

This paper presents a novel eco-friendly sensing material based on carbon paper (CP) volumetrically modified with a composite nanomodifier that includes functionalized poly(diallyldimethylammonium chloride) graphene (PDDA-G) and phytosynthesized gold nanoparticles (phyto-AuNPs). The functionalization of graphene was justified by Fourier-transform infrared spectroscopy. The phyto-AuNPs (d = 6 nm) were prepared by “green” synthesis with the use of strawberry leaf extract. The sensing material was characterized using scanning electron microscopy, electrochemical impedance spectroscopy, and voltammetry. The research results indicated a more than double increase in the electroactive surface area; a decrease in the resistance of electron transfer on nanocomposite-modified CP, compared to bare CP. The phyto-AuNPs/PDDA-G/CP was used for the electrosensing of the synthetic dye Ponceau 4R. The oxidation signal of colorant enhanced 4-fold on phyto-AuNPs/PDDA-G/CP in comparison to CP. The effect of the quantity of nanomodifier, solution pH, potential scan rate, accumulation parameters, and differential pulse parameters on the peak current of Ponceau 4R was studied. Under optimal conditions, excellent sensory characteristics were established: LOD 0.6 nM and LR 0.001–2 μM for Ponceau 4R. High selectivity and sensitivity enable the use of the sensor for analyzing the content of Ponceau 4R in food products (soft drinks, candies, and popsicles) without additional sample preparation.

“…So far different analytical techniques have been adapted for the determination of Ponceau-4R [PR] and Allura Red [AR], such as spectrophotometry 1,4 high-performance liquid chromatography 5,6 , differential pulse polarography 7 , LC-MS method 8 and electrochemical methods 9,10 . However, these methods are expensive, time consuming, complicated to operate, and requires extensive sample preparations.…”

Herein, for the first time the carbon dots (CDs) were synthesized by reflux method from sawmill waste material. We also represent a novel strategy based on fluorescent CDs for determination of ponceau 4R and allura red dyes in soft drinks. Interestingly, both the dyes were sensitive and showed effective fluorescence quenching of the CDs owing to the interaction between them. The analytical applicability of CDs were evaluated for detection of both the dyes with a good linear relationship between the concentration range of 0.0 to 3.0 µg mL−1 and having detection limit 0.45 and 0.47 µg mL−1 for allura red and ponceau 4R dyes respectively. Meanwhile, the potential application of this novel fluorescent probe for dyes determination in real samples was validated in different soft drink samples with good accuracy and precision. Thus, these findings provides new insights for the potential risk assessment of both the dyes. Moreover, CDs acted as an excellent fluorescent material in cellular imaging owing to their cellular uptake and localization.
