In this paper, Cu-doped carbon quantum dots (Cu-CQDs) were prepared by carrying out thermolysis of Na2[Cu(EDTA)] and hydroxylamine hydrochloride at 300 ºC for 2 h. The as-prepared Cu-CQDs were characterized by UV-Vis, Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The Cu-CQDs exhibited good fluorescence property, high stability, excitation-dependent emission behavior and a quantum yield of 9.8%. More significantly, the synthesized Cu-CQDs were developed for sensing rutin (RT) based on the fluorescence quenching of the prepared Cu-CQDs. A good linear relationship between the fluorescence quenching of Cu-CQDs and different concentrations of RT was obtained in the range of 0.1-15 µg mL-1 with a correlation coefficient of 0.9959. The detection limit was as low as 0.05 µg mL-1 (signal-to-noise ratio, S/N = 3). The possible mechanism of fluorescence quenching was explored, which was proved to be inner filter effect. Importantly, the proposed method was successfully applied in the detection of RT tablet samples and with satisfactory results, showing the practical applications.

In this work, a novel electrochemical detection strategy was developed based on a metal-organic framework of zinc oxide nanorod nanoparticles and rutin for selective screening of Thiourea as toxic chemicals. The zinc oxide nanorod were synthesized by following direct chemical precipitation methods and characterized by X-ray diffraction and X-ray photoelectron spectroscopy analysis. The surface of modified electrodes was also characterized by field emission scanning electron microscopes, energy-dispersive X-ray spectroscopy, and attenuated total reflectance flourier transform infrared spectroscopy. Furthermore, the electrochemical activity of the developed sensor was tested by cyclic voltammetry, differential pulse voltammetry, and electrochemical impedance spectroscopy. The modified electrode showed outstanding electro-catalytic activity towards the detection of Thiourea in phosphate buffer saline at a high pH level of 12.0. The proposed sensor showed a linear range of linearity in a concentration ranging from 5.0 × 10 −6 - 900 × 10 −6 molL −1 and a detection limit of 2.0 × 10 −6 molL −1 . Moreover, the selectivity of the developed electrochemical sensor was investigated for the detection of Thiourea in the presence of organic compounds and a group of anions. Furthermore, the proposed strategy demonstrated an excellent recovery value in the spiked farmland water and fruit juice sample.

Corneal wound healing is a highly regulated biological process that is of importance for reducing the risk of blinding corneal infections and inflammations. Traditional eye drop was the main approach for promoting corneal wound healing. However, its low bioavailability required a high therapeutic concentration, which can lead to ocular or even systemic side effects. To develop a safe and effective method for treating corneal injury, we fabricated rutin-encapsulated gelatin hydrogel/contact lens composites by dual crosslinking reactions including in situ free radical polymerization and carboxymethyl cellulose/N-hydroxysulfosuccinimide crosslinking. In vitro drug release results evidenced that rutin in the composites could be sustainedly released for up to 14 days. In addition, biocompatibility assay indicated nontoxicity of the composites. Finally, the effect of rutin-encapsulated composites on the healing of the corneal injury in rabbits was investigated. The injury was basically cured in corneas using rutin-encapsulated composites (healing rate, 98.3% ± 0.7%) at 48 h post-operation, while the damage was still present in corneas using the composite (healing rate, 87.0% ± 4.5%). Further proteomics analysis revealed that corneal wound healing may be promoted by the ERK/MAPK and PI3K/AKT signal pathways. These results inform a potential intervention strategy to facilitate corneal wound healing in humans.

Carbon dots (CDs) prepared from biomass usually produce poor quantum yield and reproducibility. A fine separation of raw materials may enhance the fluorescence performance. In this work, embryos of cumin seeds were precisely chosen as the carbon source to prepare (CDs) through hydrothermal method. The obtained product (CDs-E) possessed a higher quantum yield of 10.60 % than those synthesized with testas or whole seeds, which may be due to the relatively smaller particle size and more C-N functional groups. Rutin, as a common natural active component, could quench the fluorescence of CDs-E notably through internal filtering effect. Herein, a highly selective fluorescent sensor based on CDs-E for detecting rutin was proposed with a linearity range of 0.05 ∼ 30 μM and a detection limit of 0.015 μM obtained. Additionally, the developed method was successfully applied for the detection of rutin in Flos Sophorae , rutin tablets and capsules. This work showed the significance of fine classification for natural carbon source in preparation of CDs and provided a feasible method for quality monitoring of rutin-related pharmaceuticals, health care products and traditional Chinese medicinal materials.

In this work, multi-layer Ti 3 C 2 – carbon nanotubes – gold nanoparticles (Ti 3 C 2 -CNTs-Au) and cyclodextrin metal-organic framework – carbon nanotubes (CD-MOF-CNTs) have been prepared by in situ growth method and used to construct the ultra-sensitive rutin electrochemical sensor for the first time. Among them, the large number of metal active sites of Ti 3 C 2 , the high electron transfer efficiency of CNTS, and the good catalytic properties of AuNPs significantly enhance the electrochemical properties of the composite carbon nanomaterials. Interestingly, CD-MOF has a unique host–guest recognition and a large number of cavities, molecular gaps, and surface reactive groups, which gives the composite outstanding accumulation properties and selectivity for rutin. Under the optimized conditions, the constructed novel sensor has satisfactory detection performance for rutin in the range of 2 × 10 −9 to 8 × 10 −7 M with a limit of detection of 6.5 × 10 −10 M. In addition, the sensor exhibits amazing anti-interference performance against rutin in some flavonoid compounds and can be used to test natural plant samples (buckwheat, Cymbopogon distans , and flos sophorae immaturus). This work has promising applications in the field of environmental and food analysis, and exploring new directions for the application of Mxene-based composites.

This study aimed to overcome two inherent limitations of ovalbumin (OVA), specifically its high allergenicity and limited foaming properties, through the formulation of OVA-rutin complexes. Various modification levels of OVA-Rutin complexes were successfully produced, as confirmed by polyphenol binding equivalents and amino acid residues changes. Multispectral analyses collectively demonstrated that rutin promoted structural loosening in OVA and improved its molecular flexibility. At an OVA-Rutin ratio of 1:0.4, the IgE binding capacity diminished by 35.70%. Meanwhile, the system exhibited superior Fe 2+ chelation ability (50.88±0.31%), DPPH radical scavenging capability (67.18±2.25%) and ABTS radical scavenging ability (87.23±0.50%). The combination of rutin and OVA significantly increased foaming ability by 75.56-155.24% and foaming stability by up to 1.32-fold. This improved foam performance was attributed to the desirable air-water interfacial activity and rearrangement capacity of the OVA-Rutin complexes. These findings provide an effective strategy for simultaneously enhancing foaming properties of OVA and mitigating its allergenicity.

Rutin is a widely known plant secondary metabolite that exhibits multiple physiological functions. The present study focused on screening for synergistic antibacterial combinations containing rutin, and further explored the mechanisms behind this synergy. In vitro antibacterial test results of rutin showed that the ranges of minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) are 0.125–1 and 0.125–2 mg/mL, respectively. However, rutin and amikacin have a significant synergistic effect, with a fractional inhibitory concentration index (FICI) range of 0.1875–0.5. The time bactericidal curve proved that the combination of rutin and amikacin inhibited bacterial growth within 8 h. Scanning electron microscopy (SEM) revealed that a low-dose combination treatment could disrupt the cell membrane ofEscherichia coli(E. coli). A comprehensive analysis using alkaline phosphatase (AKP), K+, and a protein leakage assay revealed that co-treatment destroyed the cell membrane ofE. coli, resulting in the significant leakage of AKP, intracellular K+, and proteins. Moreover, confocal laser scanning microscopy (CLSM) and red–green cell ratio analysis indicated severe damage to theE. colicell membrane following the co-treatment of rutin and amikacin. This study indicates the remarkable potential of strategically selecting antibacterial agents with maximum synergistic effect, which could significantly control antibiotic resistance.

Cisplatin (CDDP) is a widely used chemotherapeutic agent, but its clinical applications are constrained by ototoxic side effects. Currently, few effective strategies exist to prevent or mitigate CDDP-induced ototoxicity. Rutin is known for its cell-protective effects by reducing oxidative stress and inhibiting apoptosis. However, its limited water solubility and inefficient delivery to the inner ear pose substantial challenges. To address this, rutin is encapsulated in liposomes (Lip-Rutin) for nanoscale drug delivery, leveraging its antioxidant properties. Lip-Rutin markedly attenuates CDDP-induced oxidative stress damage and apoptosis, demonstrating a protective effect on OC-1 cells. The efficacy of Lip-Rutin in safeguarding against CDDP-induced ototoxicity is further validated through in vivo studies. Consequently, Lip-Rutin emerges as a promising novel therapeutic agent for combating CDDP-induced ototoxicity.

For the first time, we developed a facile, green and low-cost strategy to prepare blue-green emitting fluorescence copper nanoclusters (Cu NCs) by using tyrosine as a protecting agent and hydrazine hydrate as a reducing agent. The tyrosine-protected Cu NCs (Tyr-Cu NCs) were analyzed through fluorescence spectroscopy, UV–vis absorption spectroscopy, fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The as-prepared Cu NCs was well dispersed and possessed good water solubility, excellent photostability and resistance to sodium chloride. The fluorescence intensity of Tyr-Cu NCs (around 480 nm under the excitation wavelength of 435 nm) was obviously quenched in the presence of rutin. According to this characteristic, a selective and sensitive fluorescence analytical method for the determination of rutin was established. The analytical method had a good linear relationship between F 0 /F and the concentrations of rutin (range from 0.1–60 μM) and the detection limit (LOD) was 0.016 μM. The possible mechanism of fluorescence quenching was caused by the IFE and static quenching. Meaningfully, the fluorescent probe was successfully employed to detect rutin in bovine serum samples.

Fabrication of multicomponent nanocomposites as electrode-modified materials is an effective strategy to design highly active electrochemical sensors. Here, we present a facile strategy to fabricate the palladium phthalocyanine-multiwalled carbon nanotube (PdPc-MWCNTs) nanocomposite for the sensitive detection of rutin. Results showed that the prepared nanocomposites exhibited excellent electrocatalytic activity toward rutin due to the synergetic effects of PdPc and MWCNTs (excellent electric conductivity and catalytic activity) and the homogeneous dispersibility of Nafion. Under the optimized conditions, the developed sensor exhibited a linear response range from 0.10 to 51 μM for rutin with a low detectable limit of 75 nM and a fast response less than 3.0 s. The proposed method might offer a possibility for electrochemical analysis of rutin in Chinese medical analysis or serum monitoring owing to its low cost, simplicity, high sensitivity, good stability, and few interferences against common coexisting ions in real samples.

BACKGROUND Rutin is a natural bioactive flavonoid that is poor in water solubility and chemical stability. Encapsulation can be used to protect bioactive molecules from chemical or physical decomposition during food processing and storage. Thus, the effect of initial particle size on the ability of oil-in-water emulsions to retain rutin during storage was investigated. RESULTS Rutin was encapsulated in oil-in-water emulsions with different mean surface-weighted diameters: d 3,2 = 0.56 μm (small), 0.73 μm (medium), and 2.32 μm (large). As expected, the resistance of the emulsions to coalescence and creaming during storage increased as the particle size decreased due to weakening of the colloidal and gravitational forces acting on the droplets. The concentration of rutin in the emulsions decreased during storage (28 days), which was mainly attributed to photodegradation of the flavonoid. The loss of rutin from the emulsions during storage was fitted using a second-order equation. The rutin degradation rate constant k decreased and the half-life t 1/2 increased with decreasing droplet size, which was attributed to the stronger encapsulation and light scattering by smaller oil droplets reducing the amount of light that can penetrate into the emulsions. CONCLUSION This study has important implications for the design of more efficacious emulsion-based delivery systems for incorporating health-promoting nutraceuticals into foods. © 2022 Society of Chemical Industry.

Rutin is a natural antioxidant flavonoid compound with anti-inflammatory, antioxidant, and antiviral effects that is used to prepare drugs with wide application in clinical treatment. Therefore, the quantitative detection of rutin has important practical significance. In this work, a novel electrochemical sensor based on glassy carbon electrodes (GCEs) modified with sodium carboxymethylcellulose (CMC), multi-walled carbon nanotubes (MWCNTs), and 1-butyl-3-methylimid (ionic liquid, IL) was developed for the super-sensitive detection of the flavonoid rutin. The properties of these modified materials were analyzed by transmission electron microscope (TEM), cyclic voltammograms (CVs), and electrochemical-impedance spectroscopy (EIS). CMC was used to disperse MWCNTs to further enhance their hydrophilicity and biocompatibility. The modified MWCNTs improved the sensitivity of rutin detection. The square-wave voltammetry (SWV) technique showed that the linear range of rutin concentration determination was 0.01 μM to 1 µM and 1 µM to 10 µM. The minimum concentration detection of rutin was 0.83 nM and 6.6 nM, respectively. The proposed sensor presented good selectivity for rutin and successfully analyzed rutin content in the pharmaceutical rutin tablets. These results are consistent with those measured by ultra-high-performance liquid chromatography (UHPLC). Therefore, this sensor has latent application value in the analysis of rutin in food and drug tablets and nutraceutical samples.Keywords:sensor;multi-walled carbon nanotubes;ionic liquid;sodium carboxymethylcellulose;rutin
