The use of two-dimensional heterostructure composite as electrode modification material has become a new strategy to improve the electrocatalytic activity and electroactive sites of electrochemical sensor. Herein, a soluble heterostructure, namely rGO-PSS@MXene, was designed and synthesized by integrating poly (sodium p -styrenesulfonate)-functionalized reduced graphene oxide into MXene nanosheets via ultrasonic method. The interactive heterostructure can effectively alleviate the self-stacking of MXene and rGO, endowing them with superior electron transfer capacity and large specific surface area , thereby producing prominent synergistic electrocatalytic effect towards rutin . In addition, the excellent enrichment effect of rGO-PSS@MXene for rutin also plays an important role through the electrostatic and π-π stacking interactions. The electrochemical characteristics of rutin on the sensor were examined in detail and a sensitive sensing method was proposed. Under optimized conditions, the method showed satisfactory linear relationship for rutin in the concentration range of 0.005–10.0 μM, with limit of detection of 1.8 nM (S/N = 3). The quantitative validation results in herbal medicine and commercial Tartary buckwheat tea were highly consistent with the labeled quantity and the results of HPLC determination, respectively, suggesting the sensor possessed excellent selectivity and accuracy. This proposed strategy for rutin determination is expected to expand the application of MXene heterostructure in electrochemical sensors, and is envisioned as a promising candidate for quality monitoring of drugs and foods.

Taking the extraction amount of rutin as the index, the extraction process of rutin from Ilex asprella (Hook. et Arn.) Champ. ex Benth. using the ultrasonic-assisted deep eutectic solvent method was optimized through response surface method. The effects of various factors, including the types of deep eutectic solvent, molar ratio of the solvent, water content, liquid-solid ratio, the temperature, power and time of ultrasound on the extraction amount of rutin were investigated. In accordance with the result of univariate experiments, the extraction process was optimized through employing the Box-Behnken response surface design method. A three-factor, three-level experimental model was established with the liquid-solid ratio, water content and ultrasonic time as variables. The findings indicated that the optimal technological conditions were as stated below: the molar ratio of lactic acid to choline chloride at 1:1, the ultrasonic extraction temperature at 40 °C, the ultrasonic extraction time at 31 min, the water content at 28%, and the liquid-solid ratio at 20:1 mL/g. Under optimal conditions, the validation experimental result revealed that the extraction amount of rutin was 86.553 ± 1.35 µg/g, with an absolute error of less than 0.6% in comparison with the predicted value of the model. The use of deep eutectic solvents for the extraction of rutin and the application of response surface method for optimizing the extraction process of rutin from Ilex asprella (Hook. et Arn.) Champ. ex Benth. were demonstrated. The present study provided a reference for the comprehensive utilization of Ilex asprella (Hook. et Arn.) Champ. ex Benth. .

Burn injury has posed devastating burdens on the public health due to its inevitable damage to the skin structure resulting in the increased risk of infection. Therefore, it is highly demanding to develop efficacious antibacterial wound-healing dressing. Despite the favourable wound-healing activities, the curative efficacy of phytochemical compounds of quercetin (Qe) and its derivatives is limited by their poor water solubility. Here, we have fabricated a novel electrospun nanofiber membrane (ENM) consisting of polycaprolactone (PCL), chitosan oligosaccharides (COS), and Qe/Rutin (Ru) as the potential bioactive dressing for wound healing. The incorporation of chitosan oligosaccharides (COSs) in the PCL scaffold at the optimized molar ratio not only contributed to the improved hydrophilicity and water absorption performance of the ENM but effectively increased the specific surface area of the formed nanofibers. In particular, the antioxidant and antibacterial activities of the Qe/rutin-loaded nanofiber membranes were tested, which revealed that the PCL-COS-Qe membrane exhibited superior performance among all nanofiber membranes. Therefore, the developed PCL-COS-Qe/Ru nanofiber membranes hold enormous potential as healthcare products, such as wound dressings for burn injuries.

In this study, we developed a simple, sensitive, low-cost and label-free method to detect rutin by using double-stranded DNA-templated copper nanoclusters (dsDNA-CuNCs) as a fluorescent probe. The dsDNA-template can facilitate the formation of highly fluorescent CuNCs with a maximum emission wavelength of 575 nm. In the dsDNA-CuNC fluorescent probe, rutin was intercalated into the structure of dsDNA via hydrogen bonding and electrostatic interactions. The fluorescence of dsDNA-CuNCs was quenched considerably due to the electron transfer from CuNCs to rutin. This decrease in the fluorescence intensity of dsDNA-CuNCs can be used to monitor the concentration of rutin from 0.6 to 400 μM with a detection limit of 0.12 μM (S/N = 3). Compared with the previous reports, this method does not require any complex DNA sequence design, fluorescent dye label and sophisticated experimental techniques. Moreover, the proposed sensing system could be applicable for the detection of rutin in pharmaceutical samples.

In this paper, a CdSe quantum dots (QDs) sensitized TiO 2 photoanode was synthesized by molten-salt-assisted self-assembly (MASA) on a fluorine-doped tin oxide (FTO)-coated glass (CdSe QDs-TiO 2 /FTO), and an efficient photoelectrochemical (PEC) sensor was constructed for the sensitive detection of rutin. CdSe can transfer photo-excited electrons to the conduction band of TiO 2 , thus enhancing the photoelectric activity of TiO 2 . The experimental results show that the PEC sensor has excellent selectivity, good stability, and a wide linear response range for rutin of 0.025–50.0 μM with a low detection limit of 0.007 μΜ. Moreover, the PEC sensor was successfully applied to the detection of rutin content in serum sample.

A novel graphene oxide doped poly(hydroxymethylated-3,4-ethylenedioxythiophene) (PEDOT-MeOH/GO) composite film was synthesized and utilized as an efficient electrode material for simultaneous detection of rutin and ascorbic acid (AA). PEDOT-MeOH/GO films were synthesized on glassy carbon electrode (GCE) by a facile one-step electrochemical approach and were characterized by scanning electron microscopy, UV-Vis spectroscopy, FTIR spectra and electrochemical methods. Then the PEDOT-MeOH/GO/GCE was applied successfully in the simultaneous detection of rutin and AA. The results showed that the oxidation peak currents of rutin and AA obtained at the PEDOT-MeOH/GO/GCE were much higher than those at the traditional conducting polymer PEDOT/GO/GCE, PEDOT-MeOH/GCE, PEDOT/GCE and bare GCE. Under optimized conditions, the linear ranges for rutin and AA are 20 nmol/L−10 μmol/L and 8 μmol/L−1 mmol/L, respectively. The detection limit is 6 nmol/L for rutin and 2 μmol/L for AA (S/N = 3), which are lower than those of the reported electrochemical sensors.

Tartary buckwheat bran (TBB), which is rich in proteins, is the main waste of tartary buckwheat processing. To improve the value of TBB, the noncovalent and covalent Tartary buckwheat bran protein (TBBP)/rutin complexes were prepared, and their capacities to fabricate β-carotene nanoemulsions were compared. The results indicated that the covalent complex exhibited the highest emulsifying performance, and the corresponding nanoemulsion had the lowest droplet size and polymer dispersity index (PDI) and the highest absolute value of ζ-potential, which could remain stable for four weeks. The high–temperature–short–time treatment and freeze–thaw processing had little influence on this nanoemulsion. However, it was very sensitive to high salt concentrations. Compared with the nanoemulsion prepared by the noncovalent complex, it had higher protein and rutin concentrations at the oil-water interface, which explained the improved stability of β-carotene against high temperature and UV irradiation. Practical applications In this study, the fabrication and characterization of β-carotene nanoemulsion stabilized by the complexes of tartary buckwheat bran protein and rutin are introduced. It can provide a reference for the utilization of other low-value cereal proteins and prompt the development of nutraceutical delivery systems based on food-derived protein-polyphenol complexes.

In this study, a simple and effective method was proposed to improve the electrocatalytic ability of overoxidized poly(3,4-ethylenedioxythiophene)-overoxidized polypyrrole composite films modified on glassy carbon electrode for rutin and luteolin determination. The composite electrode was prepared by cyclic voltammetry copolymerization with LiClO 4 -water as the supporting electrolyte. The peak current of rutin and luteolin on the composite electrode gradually decreased or even disappeared with the increase in the positive potential limit. After incubation in NaOH-ethanol solution with a volume ratio of 1:1, the composite electrodes prepared at positive potential limit greater than 1.5 V exhibited enhanced differential pulse voltammetry peak currents, reduced charge transfer resistance, larger effective specific surface area and higher electron transfer rate constant. The composite electrode prepared in the potential range of 0–1.7 V showed optimal electrocatalytic performance. The X-ray photoelectron spectroscopy results indicated that the content of −SO 2 /−SO and −C=N− groups in the composite film increased significantly after incubation. Further, the Raman spectra and Fourier transform infrared spectra revealed that the thiophene ring structure changed from benzene-type to quinone-type, and the quinone-type pyrrole ring was formed. The electrocatalytic mechanism of the composite film was proposed based on the experimental results and further verified by Density Functional Theory calculation.

Resveratrol and rutin, two polyphenolic compounds, can effectively alleviate the symptoms of ulcerative colitis (UC), leading to conflicts in recommending resveratrol- or rutin-rich diets to UC patients, who do not know which type of diet is more effective in alleviating UC symptoms. In this study, administration of resveratrol or rutin alleviated DSS-induced UC mice, including reduction of DAI, serum levels of inflammatory cytokines and oxidant, and improvement of colonic health status. Differentially expressed genes resulting from resveratrol and rutin treatment in DSS-induced UC mice at the genome-wide level from scratch and elucidated the mechanism by which they affected the polarization of intestinal epithelial T cells by promoting Treg cells and inhibiting Th17 cells to alleviate UC symptoms, and rutin was greater than resveratrol. In addition, rutin-rich foods were superior to resveratrol-rich foods in ameliorating UC symptoms in mice. Our findings suggest that UC patients consume rutin-rich foods to better alleviate intestinal inflammation.

Manganese oxide nanoparticles (MONs)-based contrast agents have attracted increasing attention for magnetic resonance imaging (MRI), attributed to their good biocompatibility and advantageous paramagnetism. However, conventional MONs have poor imaging performance due to low T 1 relaxivity. Additionally, their lack of tumor-targeting theranostics capabilities and complex synthesis pathways have impeded clinical applications. Rutin (Ru) is an ideal tumor-targeted ligand that targets glucose transporters (GLUTs) overexpressed in various malignant tumors, and exhibits photothermal effects upon chelation with metal ions. Herein, a series of Ru-coated MONs (Ru/MnO 2 ) were synthesized using a straightforward, rapid one-step process. Specifically, Ru/MnO 2 -5, with the smallest crystal size of approximately 4 nm, exhibits the highest T 1 relaxivity (33.3 mM -1 s −1 at 1.5 T, surpassing prior MONs) along with notable stability, photothermal efficacy, and tumor-targeting ability. Furthermore, Ru/MnO 2 -5 shows promise in MRI and photothermal therapy of H22 tumors owing to its superior GLUTs-mediated tumor-targeting capability.

One-pot synthesis of rGO/PEDOT:PSS/Ru composite for targeted flavonoid sensing. • PEDOT:PSS prevents rGO restacking and enables uniform Ru nanoparticle dispersion. • Interfacial coupling downshifts Ru d-band center to accelerate oxidation kinetics. • Ternary architecture greatly minimizes charge-transfer resistance at the interface. Flavonoid quantification is essential for pharmaceutical and food quality control, yet direct electrochemical detection is hindered by sluggish heterogeneous electron-transfer kinetics and limited current responses at trace concentrations on unmodified electrodes. We report an electrochemical sensing platform based on an rGO/PEDOT:PSS/Ru nanocomposite. Structural characterization indicates that π-π stacking between rGO and PEDOT:PSS prevents graphene restacking, enabling uniform Ru nanoparticle distribution. Crucially, interfacial electronic coupling within the ternary network downshifts the d-band center of the Ru nanoparticles, thereby accelerating the electro-oxidation kinetics. Electrochemical kinetic analyses reveal that the analytes undergo an adsorption-controlled, two-electron and two-proton (2e - /2H + ) transfer pathway. This architecture significantly minimizes charge-transfer resistance and expands the electroactive surface area. Differential pulse voltammetry delivered linear ranges of 0.006–65.0 μM (rutin), 0.05–70.0 μM (quercetin), and 0.02–50.0 μM (baicalin), with detection limits of 3.7, 17.3, and 6.3 nM, respectively. The sensor maintained consistent responses over 15 days and exhibited reliable selectivity against common interferents. Recovery studies in Sophora japonica, onion, and Scutellaria baicalensis extracts correlated with UV–Vis reference data, illustrating how coupling conducting polymers with redox-active nanoparticles can modulate interfacial electron-transfer pathways for targeted electrochemical sensing.

The electrocatalytic oxidation of glutathione based on rutin as a mediator was studied at acetylene black (AB) modified carbon paste electrode (CPE). The results of cyclic voltammetric experiments showed that rutin could catalyze oxidation of GSH in PBS (pH 7.0) and the oxidation current was greatly increased by using AB-CPE compared to the nonmodified CPE. The kinetic parameters such as catalytic rate constant and diffusion coefficient were obtained using double potential step chronoamperometry. Under the optimum conditions, the electrocatalytic oxidation peak current was linear to the glutathione concentration range from 0.5 μM to 3.5 μM and 2.5 μM to 25 μM with the detection limit of 0.080 μM (S/N = 3) by differential normal pulse voltammetry (DNPV). The proposed method has been applied to the determination of glutathione in pharmaceutical sample with satisfactory results.
