A new micro-solid-phase extraction method based on a prestructured filter membrane was developed to facilitate simultaneous analysis of tartrazine (TA) and sunset yellow (SY) with high performance liquid chromatography (HPLC). A filter membrane impregnated with nano-Al2O3 particles was proposed as a new micro-solid-phase extraction (μ-SPE) device for the preconcentration of colorants in food. The method integrated isolation and concentration in one step, and the adsorbed colorants could be easily eluted from the filter membrane for HPLC analysis. This process does not involve any additional sample treatment. The method is facile and easy to operate. The method showed good linearity, with correlation coefficients >0.9982 in the range of 1.0–200.0 ng mL−1, and low limits of detection (0.10–0.20 ng mL−1). Finally, the recovery values were 86.9–124.0% for the colorants in various food samples. The results indicated that the developed method would be a novel method for rapid determination of TA and SY at trace levels in real samples.

A highly sensitive method for simultaneous electrochemical determination of Sunset yellow (SY) and Tartrazine (Tz) in foods was proposed based on the stable aqueous dispersions of polypyrrole (ppy) decorated oxidized single-walled carbon nanotubes (SCNT-COOH). Under optimal experimental conditions, the dispersions modified glassy carbon electrode (GCE) exhibited remarkable sensitivity of (72.36 μA/μM and 23.39 μA/μM) with wide linear responses to Sunset yellow and Tartrazine ranging from 5.0 × 10−9 to 1.0 × 10−6 M and 7.0 × 10−9 to 1.0 × 10−6 M, and detection limits as low as 7.0 × 10−10 M and 1.0 × 10−9 M for Sunset yellow and Tartrazine, respectively, which might be due to hydrogen bonds between hydroxyl groups of dyes and oxygen-containing groups of the composite. In addition, the electrostatic interaction between the dyes and the ppy may also play a main role except for good dispersibility.

Excessive consumption of Sunset Yellow (SY) and Tartrazine (Tz) might cause adverse effects on human health. Hence, it is essential to develop a rapid and reliable technique for simultaneous determination of SY and Tz. Herein, an innovative voltammetric sensor was constructed for simultaneous determination of SY and Tz using multiwalled carbon nanotubes decorated dandelion-like α-MnO 2 microspheres (MnO 2 /MWCNTs). The physiochemical properties of MnO 2 /MWCNTs were studied by various microscopic, spectroscopic, and electrochemical techniques. Various parameters, including accumulation time, accumulation potential, loading volume, buffer pH, and scanning rate, were systematically explored in order to pursuit the higher peak current response. The MnO 2 /MWCNT effectively enlarged the electroactive surface area and expedited the electron transfer. As a result, the MnO 2 /MWCNT decorated glassy carbon electrode (GCE) displayed superior sensing performance for the electrooxidation of SY and Tz over a wide concentration range (0.06–10 μM), owing to the synergistic effect from dandelion-like α-MnO 2 microspheres and highly conductive MWCNTs. The detection limits were 0.005 and 0.01 μM for SY and Tz, respectively. In addition, the MnO 2 /MWCNT/GCE demonstrated strong anti-interfering capacity against potential interfering species, and highly reproducible electrode manufacture. The MnO 2 /MWCNT/GCE was successfully employed for the simultaneous and sensitive determination of SY and Tz in carbonate beverage with good recovery.

A molecularly imprinted electrochemiluminescence (ECL) sensor was developed for ultrasensitive tartrazine (TZ) detection. The system employed Ru(bpy) 3 2+ encapsulated in UiO-66 as the luminophore, with tri-n-propylamine (TPrA) as co-reactant. Carbon nitride nanosheets (CNNS) functionalized with Ag nanoparticles (Ag NPs) enhanced the ECL signal through resonance energy transfer, while the UiO-66@Ru(bpy) 3 2+ /CNNS@Ag NPs/TPrA combination provided synergistic signal amplification. Selective recognition was achieved through a molecularly imprinted polymer (MIP) layer fabricated by electropolymerizing pyrrole with TZ as template. Target binding induced ECL quenching via electron transfer inhibition, enabling quantification. The sensor showed excellent performance with a wide linear range (1.0 × 10 −12 -1.0 × 10 −6 mol L −1 ) and low detection limit (3.3 × 10 −13 mol L −1 , S/N = 3). Practical utility was demonstrated through successful TZ determination in food samples, highlighting its potential for synthetic dye monitoring in complex matrices. The integration of advanced nanomaterials with MIP technology resulted in a sensitive, selective, and practical sensing platform.

Colorant tartrazine is widely used in the food industry, but its long-term and excessive consumption is harmful to human health. Therefore, it is necessary to establish a sensitive detection method for tartrazine. Blue fluorescent carbon dots with L-arginine and o-phenylenediamine as precursors, namely L-Arg/oPD-CDs, were prepared via the hydrothermal method. Then, L-Arg/oPD-CDs were further purified by dialysis, thin layer chromatography and column chromatography. A dual-mode nanosensor based on fluorescent and UV absorption was successfully developed. Excellent linear ranges of 0–5 μM and 10–50 μM were obtained with a low detection limit of 42.3 nM based on fluorescence. A good linear range of 0–50 μM was obtained with a low detection limit of 130.15 nM based on UV absorption. The quenching mechanism of tartrazine towards L-Arg/oPD-CDs fluorescence was the inner filter effect. In addition, a dual-mode nanosensor was used for tartrazine determination in millet, maize flour, carbonated drink, and sugar samples. This study provides new insight into the detection of tartrazine by applying a dual-mode nanosensor.

Sulfur quantum dots (SQDs), the rising star in fluorescent nanomaterials, have captured increasing attention due to their unique attributes. However, the development of SQDs with targeted fluorescence response to analyte is still a challenge. Herein, we report a robust fluorescent SQDs material that possess both molecular recognition and fluorescence detection capability by employing hydroxypropyl-β-cyclodextrin (HP-β-CD) as ligand. The prepared SQDs simultaneously display fine aqueous dispersibility, stable and tunable fluorescence, and favorable biocompatibility, which enable them promising for applications in cellular imaging and sensing. Owing to the synergistic effect of inner filter effect (IFE) and host-guest interaction, the SQDs can be utilized as an effective fluorescent probe for tartrazine (TTZ) detection with excellent sensitivity and selectivity. The limit of detection can reach 82 nM with a wide linear range of 0–30 μM. Furthermore, the fluorescent SQDs were successfully utilized to detect TTZ in river water and food samples with satisfactory performance.

Tartrazine (TZ) is an azo dye widely used in foods, cosmetics, beverages, textile, and leather. In recent years, there are reports on detecting azo dyes in the aquatic environment, so the impact of these compounds on aquatic organisms could not be ignored. In this study, we aimed to evaluate the adverse effects of TZ exposure on teleosts’ embryo development and juvenile's health by using crucian carp ( Carassius carassius ) as the experimental fish. The results showed that embryos exposed to TZ (0.19, 0.76 and 1.5 mM) exhibited a deformity, delayed egg resorption and decreased fertilization and hatching rate. When the juvenile fish were exposed to TZ at a level higher than those present in water for 30 days caused severe histopathological damages of the gill, intestine, kidney and liver. Antioxidant enzymes (CAT, SOD and GSH-Px) activities in the gill, intestine and liver, exhibited a decreasing trend after TZ exposure, while MDA contents elevated. TZ exposure also resulted in the upregulation of pro-inflammatory cytokines ( il1 and il6 ), lysozymes ( lyz ), complement component 3 ( c3 ), and β-defensin 3 ( defb3 ). In addition, TZ exposure also affected the intestinal microbiota structure. In summary, the data in the present study indicated that TZ exposure reduce the embryo fertilization and hatching rate; cause histopathological damage of tissues, trigger oxidative stress, innate immune disorders and dysbiosis of gut microbiota in juvenile crucian carp. Therefore, it is necessary to be informed about the hazards of TZ exposure and the discharge of the dye into waters should be strictly administrated to prevent environmental pollution.

In the work, water-soluble bovine serum albumin-protected fluorescent nickel nanoclusters (BSA-NiNCs) are used as fluorescent probes to construct a label-free fluorescence quenching sensor for sensitive and selective detection of tartrazine . The fluorescent BSA-NiNCs are synthesized in one pot using BSA as both the template and reducing agent, and hydrogen peroxide as the additive. The as-prepared NiNCs are characterized by using various analytical techniques like transmission electron microscopy , X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, UV–Vis absorption spectroscopy, circular dichroism spectroscopy, and fluorescence spectroscopy. The synthesized BSA-NiNCs have a quantum yield of ca. 8% by using quinine sulfate as a standard. The sensor for tartrazine detection shows a wide linear range of 0.01–3.5 μM, with a low detection limit of 4 nM. The fluorescence quenching very likely results from the combination of the intermolecular interactions and the secondary inner filter effect between BSA-NiNCs and tartrazine. Then, the proposed sensor is successfully employed for tartrazine detection in drink samples, and the results are comparable with those based on a reference HPLC method.

A novel electrochemical sensor designed to recognize and detect tartrazine (TZ) was constructed based on a molecularly imprinted polydopamine (MIPDA)-coated nanocomposite of platinum cobalt (PtCo) nanoalloy-functionalized graphene oxide (GO). The nanocomposites were characterized and the TZ electrochemical detection performance of the sensor and various reference electrodes was investigated. Interestingly, the synergistic effect of the strong electrocatalytic activity of the PtCo nanoalloy-decorated GO and the high TZ recognition ability of the imprinted cavities of the MIPDA coating resulted in a large and specific response to TZ. Under the optimized conditions, the sensor displayed linear response ranges of 0.003–0.180 and 0.180–3.950 µM, and its detection limit was 1.1 nM (S/N = 3). The electrochemical sensor displayed high anti-interference ability, good stability, and adequate reproducibility, and was successfully used to detect TZ in spiked food samples. Comparison of important indexes of this sensor with those of previous electrochemical sensors for TZ revealed that this sensor showed improved performance. This surface-imprinted sensor provides an ultrasensitive, highly specific, effective, and low-cost method for TZ determination in foodstuffs.Keywords:platinum cobalt nanoalloy;molecularly imprinted polydopamine;graphene oxide;tartrazine;electrochemical sensor

A novel tartrazine imprinted polymer – multiwalled carbon nanotubes - ionic liquid supported Pt nanoparticles composite film coated glassy carbon electrode (MIP–MWNTs-IL@PtNPs/GCE) was presented. It was fabricated by coating a GCE with MWNTs-IL@PtNPs mixture, followed by MIP suspension. The IL functionalized MWNTs was prepared by Click chemistry, and Pt nanoparticles were then loaded on it using ethylene glycol as reducing agent. The MIP was prepared by typical free radical polymerization using 4-vinylpyridine as functional monomer. The resulting MIP–MWNTs-IL@PtNPs/GCE showed good analytical performance when it was used for the electrochemical determination of tartrazine. Under the optimized conditions, the peak current was linear to tartrazine concentration in the ranges of 0.03 – 5.0 μM and 5.0 – 20 μM with sensitivities of 0.72 μA/μM mm 2 and 0.24 μA/μM mm 2 , respectively; the detection limit was 8 nM (S/N = 3). The sensor was successfully applied to the determination of tartrazine in practical samples and the recovery for the standards added was 88 – 108%.

A novel electrochemical sensing platform was designed for simultaneous determination of Ponceau 4R and Tartrazine using an ionic liquid modified expanded graphite paste electrode (IL-EGPE). The IL-EGPE was prepared by mixing ionic liquid-expanded graphite composite (IL-EG) with solid paraffin. Based on the advantageous functions of IL and EG, IL-EGPE showed excellent electrocatalytic activity toward the simultaneous oxidation of Ponceau-4R and Tartrazine. Due to the electrocatalytic activity to Ponceau-4R and Tartrazine, a sensor for Ponceau-4R and Tartrazine was constructed based on IL-EGPE. Under optimal experimental conditions, the designed sensor exhibited wide linear responses to Ponceau 4R and Tartrazine ranging from 1.0 × 10−8 to 5.0 × 10−6 mol/L and 1.0 × 10−8 to 2.0 × 10−6 mol/L, respectively. The detection limits for Ponceau 4R and Tartrazine were 1.4 × 10−9 mol/L (0.85 ng/mL) and 3.0 × 10−9 mol/L (1.6 ng/mL) at a signal-to-noise ratio of 3, respectively. This sensor showed good reproducibility, stability and reusability. The proposed sensor was successfully applied in the simultaneous determination of Ponceau-4R and Tartrazine in soft drink with satisfactory results.
