Fe–polyphenols coordination polymers have emerged as a versatile theranostic nanoplatform for biological applications owing to the appealing biocompatibility of precursors from nature. Incorporating bioactive molecules with Fe–polyphenols coordination polymers is greatly significant to take full advantages of their superiorities for advanced application. Herein, we show functional-protein-assisted fabrication of Fe–gallic acid (GA) nanonetworks via a mild and facile biomineralization for photothermal therapy. Mild alkaline condition is crucial to obtain protein–Fe–GA nanonetworks with intense near-infrared absorption and their unique network structure allows reducing the leakage to the surrounding normal tissues, benefiting high photothermal therapeutic efficacy and minimal side effects. The proposed bovine serum albumin–Fe–GA nanonetworks are successfully used to eradicate tumor in vivo. In addition, this universal method can be extended to synthesize other protein-involved nanonetworks, such as human serum albumin–Fe–GA and ovalbumin–Fe–GA. More importantly, the intrinsic bioactivity of protein can be retained in the nanonetworks, and the ovalbumin–Fe–GA nanonetworks enable inducing the maturation of immune cells, showing the successful fusion of immune activity of ovalbumin into the nanonetworks. The proposed biomineralization strategy shows a bright prospect in incorporating various functional proteins, such as enzymes and antibodies, to form protein–Fe–GA nanonetworks with good biocompatibility, favorable photothermal effect, and specific biological function.

The solubility of gallic acid (GA) in butan-1-ol, butan-2-ol, hexan-1-ol, 1,4-dioxane, ethyl acetate, methyl acetate and cyclohexanone from 293.15 to 318.15 K has been experimentally measured using a thermostatted reactor and UV/vis spectrophotometer analysis. The results demonstrate that the solubility of GA generally increased with the temperature and at a given temperature decreased with the increase of the carbon number of alcohols. The van’t Hoff model, modified Apelblat equation, λh equation and the Two Local composition models of Wilson and NRTL model were used to predict the reported solubilities, resulting in a mean relative deviation of 3.47%, 3.54%, 2.90%, 3.12% and 3.18%, respectively. The obtained data showed that the λh equation model is the most suitable for description of the solid–liquid equilibrium containing GA. Furthermore, the standard molar Gibbs energy ΔsolG⊖ and standard molar enthalpy of dissolution ΔsolH⊖ of GA were estimated.

A colorimetric assay is proposed for the selective detection of Cr(III) and Cr(VI) via the aggregation-induced color change of gallic acid capped gold nanoparticles (GA-AuNPs). The AuNPs are characterized using UV-vis spectroscopy, transmission electron microscopy (TEM), dynamic light scattering (DLS) and Fourier-transform infrared spectrometry (FT-IR). To detect Cr(III) and Cr(VI) coexisting in a sample, citrate and thiosulfate were applied to mask Cr(VI) for the detection of Cr(III), and ethylenediaminetetraacetic acid disodium salt (EDTA) was applied to mask Cr(III) for the detection of Cr(VI). At optimized experimental conditions, the selectivity of these AuNPs-based detection systems is excellent for Cr(III) and/or Cr(VI) compared with other types of metal ions. The limit of detections (LODs) of a mixture of Cr(III) and Cr(VI), Cr(III) and Cr(VI) by eye vision are 1.5, 1.5 and 2 μM, respectively, and those by UV-vis spectroscopy are 0.05, 0.1 and 0.1 μM, respectively. The minimum detectable concentrations for Cr(III) or Cr(VI) are all below the guideline value set by the US Environmental Protection Agency (EPA). The applicability of the AuNPs-based colorimetric sensor is also validated by the detection of Cr(III) and Cr(VI) in electroplating wastewater and real water samples with high recoveries.

Two novel organogelators ( TEG and TAG ) based on tetraphenylethylene and 3,4,5-tris(dodecyloxy) benzoic acid were synthesized through ester bond and amido bond linkages, respectively. Compounds TEG and TAG were able to induce gelation in ethanol. Aggregation-induced enhanced emission was observed in these organogelator molecules, with increased fluorescence intensity from the solutions to the gels. The completely thermoreversible gelation occurred due to the aggregation of the organogelators. In the process, a fibrous network was formed by a combination of intermolecular hydrogen bonding, π–π stacking and van der Waals interactions. These phenomena were observed in the xerogels by field-emission scanning electron microscopy and Fourier-transform infrared spectroscopy. The results of differential scanning calorimetry and polarized optical microscopy indicated that compound TAG exhibited stable liquid crystalline phases over a wide temperature range. The linking groups have severe influence on the properties of the organogelators, which was mainly attributed to the hydrogen bonding interaction in compound TAG .

Graphite carbon (G) @ silver (Ag) @ porous silicon Bragg mirror (PSB) composite SERS substrate was successfully synthesized using electrochemical etching (ec) and hydrothermal carbonization (HTC) techniques with silver nitrate as the source of silver and glucose as the source of carbon. The PSB was used as a functional scaffold for the synthesis of graphite-carbon and silver composite nanoparticles (G@AgNPs) on its surface, thereby combining SERS activity and antioxidant properties. To our knowledge, this is the first time that G@AgNPs has been synthesized on the PSB using glucose as a carbon source. The synthesized G@Ag@PSB was utilized as a SERS platform for the detection of gallic acid (GA). Test results demonstrated that the substrate exhibited a remarkable SERS enhancement capability for GA, with the enhancement factor (EF) reaching 2 × 10 5 . The reproducibility of the SERS spectral signal was excellent, with a relative standard deviation (RSD) of 7.5 %. The sensitivity test results showed that the linear range of GA detection based on G@Ag@PSB composite SERS substrate was 2 × 10 -3 -2 × 10 -12 M. The relationship between GA concentration and SERS signal intensity exhibited a strong linear correlation, with a linear correlation coefficient (R 2 ) of 0.97634. Moreover, even with an extended storage period, only a marginal decline in the signal intensity of GA on the substrate was observed. The results of this study demonstrate that the prepared G@Ag@PSB composite SERS substrate had good potential application performance as a low-cost SERS detection platform suitable for commercial use. In addition, this advance facilitates the further exploration of more nanomaterials with ultra-high sensitivity in SERS technology.

In order to clarify the relationship between withering process and green tea quality, dynamic changes in the major chemical components of green tea, including amino acids, catechins, caffeine (CAF) and gallic acid (GA), were investigated during withering at different times (ranging from 0 h to 21 h) and temperatures (15, 20 and 25 °C). One-way and two-way analyses of variance (ANOVA) with Duncan’s test were used to analyse the change of chemical components. Results showed that during the withering process, contents of most free amino acids increased with increasing withering time and temperature. Theanine (Thea) contents decreased slightly with fluctuations, glutamic acid (Glu) and aspartic acid (Asp) contents presented an increase–decrease pattern, whereas proline (Pro) contents remained almost constant. Total free amino acids increased up to 18 h but declined thereafter. Most catechins decreased with increasing withering time and temperature. In addition, GA contents increased with increasing time and temperature; while CAF contents increased with increasing withering time, but were only slightly correlated with withering temperature. This experiment recommended withering for 15–18 h below 25 °C to produce high quality green tea.

Developing efficient and durable functional fabrics using natural plant-derived polyphenols is environmentally friendly. Gallic acid (GA), a widely available natural polyphenol, has been extensively used for functional materials modification due to its cost-effectiveness and high reactivity. In this work, a combination of gallic acid, polyethyleneimine (PEI) and metal ions was employed to prepare flame-retardant silk fabrics through a simple impregnation-drying method. The silk fabrics modified with different metal ions (Fe 2+ , Fe 3+ , Al 3+ and Ti 4+ ) achieved self-extinguishing properties in vertical combustion tests with damaged char lengths of 9.2, 8.3, 9.3, and 8.2 cm and limiting oxygen index values of 29.8%, 30.2%, 27.4%, and 33.0%, respectively. The damaged char length of Fe 3+ -treated silk remained below 15 cm even after 50 washing cycles. The total heat release rate (THR) and peak heat release rate (pHRR) of all four silk fabrics modified with metal ions were significantly reduced in cone calorimetry tests. Concurrently, the potential flame retardant mechanisms were postulated based on the analysis of combustion products from the samples in both gaseous and condensed phases. Furthermore, the Fe 3+ -treated silk demonstrated excellent antibacterial properties. This simple approach to preparing functionalized silk fabrics provides a novel pathway for developing advanced and durable silk textiles.

As the demand for high-performance energy storage devices continues to boom, the electrode materials with large specific capacitance and long-term stability for supercapacitors have garnered significant attention. In this study, gallic acid (GA)-incorporated polyaniline (GA/PANI) nanomaterials were prepared through in situ polymerization in different reaction temperatures and different feed proportions. The formation and physicochemical features of GA/PANI were certified by XRD, FTIR, UV-Vis, and SEM analysis. The electrochemical analysis revealed an enhanced specific capacitance of 635 F g −1 at 0.5 A g −1 and a capacitance retention of 96.0% after 10,000 cyclic voltammetry tests at a scan rate of 200 mV s −1 for GA/PANI1:10. The assembled supercapacitor based on GA/PANI1:10 displays a high energy density of 49.2 Wh kg −1 at a power density of 301 W kg −1 . Therefore, these results verified the suitability of GA/PANI nanomaterial as an electrode material for the practical application in supercapacitor with long-term reliability and rate capacity.

The wheat scab caused byFusarium graminearum(F. graminearum) has seriously affected the yield and quality of wheat in China. In this study, gallic acid (GA), a natural polyphenol, was used to synthesize three azole-modified gallic acid derivatives (AGAs1–3). The antifungal activity of GA and its derivatives againstF. graminearumwas studied through mycelial growth rate experiments and field efficacy experiments. The results of the mycelial growth rate test showed that the EC50of AGAs–2 was 0.49 mg/mL, and that of AGAs–3 was 0.42 mg/mL. The biological activity of AGAs–3 onF. graminearumis significantly better than that of GA. The results of field efficacy tests showed that AGAs–2 and AGAs–3 significantly reduced the incidence rate and disease index of wheat scab, and the control effect reached 68.86% and 72.11%, respectively. In addition, preliminary investigation was performed on the possible interaction between AGAs–3 andF. graminearumusing density functional theory (DFT). These results indicate that compound AGAs–3, because of its characteristic of imidazolium salts, has potential for use as a green and environmentally friendly plant-derived antifungal agent for plant pathogenic fungi.

Selenium nanoparticles (SeNPs) are of interest for their versatility and low toxicity, but bare SeNPs are unstable and tend to aggregate and precipitate as black elemental Se, which limits the application of SeNPs. This study evaluated the physicochemical properties, physical stability, antioxidant activities and cytotoxicity of SeNPs stabilized by Grifola frondosa polysaccharides (GFPs) and GFPs-gallic acid conjugates (GFPs-GA). The results showed that the particle size (PZ), polymer index (PDI) and zeta potential (ZP) of the GFPs-SeNPs and GFPs-GA-SeNPs were 58.72 ± 0.53 nm, 0.11, −8.36 ± 0.21 mV and 61.80 ± 0.16 nm, 0.12, −9.37 ± 0.13 mV, respectively. Besides, the GFPs-SeNPs and GFPs-GA-SeNPs remained stable when stored at 4 °C for 70 days in darkness. SeNPs stabilized with GFPs have improved the antioxidant activity and selective toxicity to tumour cells. Interestingly, SeNPs stabilized with GFPs-GA further enhanced these biological activities. This work provided a simple and effective method to construct well-dispersed SeNPs in aqueous systems, demonstrating the important roles of GFPs and GFPs-GA in the size control, dispersion and stabilization of SeNPs. The prepared GFPs-SeNPs and GFPs-GA-SeNPs can serve as good selenium supplements and have potential prospects for antioxidant activity and tumour inhibition.

Dyes, tetracycline, phenol, microplastics, and oily pollutants are commonly found in wastewater. However, there is a lack of studies demonstrating the simultaneous effective removal of all these contaminants. In this study, a Fe-gallic acid (Fe-GA) complex was in situ grown on cotton fabric to develop a functional material (FGC). FGC achieved a separation efficiency of 99.0 % for carbon tetrachloride/water mixtures by gravity, with a permeation flux of nearly 50,000 L/(m 2 ·h), and maintained stability over 20 separation cycles. After 30 s of illumination, the absorption rate of FGC for engine oil nearly doubled, indicating significant photothermal oil removal capability. Furthermore, FGC exhibited superior degradation performance for various water pollutants. Within 60 min, FGC achieved degradation efficiencies exceeding 99.0 % for Rhodamine B (RhB), Methylene Blue (MB), and Acid Yellow 23 (AY 23), and a degradation efficiency of 94.9 % for tetracycline. It also demonstrated excellent degradation capabilities for mixtures of these pollutants. Notably, the degradation performance of FGC for phenol and microplastics was even more remarkable, achieving nearly complete degradation within 10 min. This study expands the application potential of textiles and provides a novel method for efficiently removing multiple pollutants from water.

As the representative volatile chlorinated hydrocarbons detected in wastewater, the removal of composite chlorinated ethenes is a major challenge in wastewater treatment. In the present study, an efficient removal system for composite chlorinated ethenes was reported, in which gallic acid was used to enhance the activation of persulfate by Fe/Ni nanoparticles. The influences of gallic acid-Fe/Ni and persulfate concentrations, initial pH value, reaction temperature, inorganic anions, and natural organic matters were evaluated in the composite chlorinated ethenes removal. Our results showed that the gallic acid-Fe/Ni-persulfate system with 9.0 mM of gallic acid-Fe/Ni and 30.0 mM of persulfate yielded about 100% trichloroethylene removal and 97.3%-98.6% perchloroethylene removal in the pH range of 3.0–12.0. Electron paramagnetic resonance analysis and radical quenching experiments indicated that SO 4 •− and • OH were the predominant radical species under acidic and alkaline conditions. Ultraviolet visible spectroscopy and inductively coupled plasma optical emission spectrometer tests revealed the Fe-gallic acid chelation could regulate the concentration of iron ions and improve the reactivity of gallic acid-Fe/Ni. These results demonstrated that the gallic acid-Fe/Ni-persulfate system was a promising strategy for treating composite chlorinated ethenes-containing wastewater.
