Although lateral flow immunoassay (LFIA) as a point-of-care (POC) diagnostic tool has been widely used because of numerous merits, it remains challenging to realize higher sensitivity, easier labeling, and fewer antibodies consumption. Herein, a bioresource-derived tannic acid (TA)-supported immuno-network based LFIA for clenbuterol (CLE) monitoring was proposed by employing poly TA nanospheres (PTAN) as the new tracer. Attributing to the effective protein-enrichment ability of TA, plenty of goat anti-mouse immunoglobulins (GAMI) were first absorbed on the surface of PTAN and then monoclonal antibodies (Ab CLE ) were added to form immuno-network. Compared with directly coupling antibodies, the utilization efficiency of Ab CLE was significantly improved. Thus, the detection sensitivity (take the cut-off value as an example) was enhanced 5-fold and 10-fold at least compared with PTAN-Ab CLE and colloidal gold-based LFIA, respectively. Additionally, the proposed method was successfully verified in beef and pork liver and provided an effective strategy for food safety monitoring.

Tannic acid (TA) film covered magnetic microspheres (Fe 3 O 4 @TA–Fe 3+ ) was synthesized and applied for removal of Pb 2+ and Hg 2+ from aqueous solution. The resulted Fe 3 O 4 @TA–Fe 3+ was characterized with thermo-gravimetric analysis, vibrating sample magnetometer, transmission electron microscope, and Fourier transform infrared spectra. The adsorption of pollutants was pH dependent because the complexation of TA with Fe 3+ was disassembled at low pH. The composites showed high maximum adsorption capacity for Pb 2+ up to 1115.3 mg/g and Hg 2+ to 279.4 mg/g. Furthermore, the Fe 3 O 4 @TA–Fe 3+ composites could be easily separated from the solution by a magnet after adsorption because of the excellent superparamagnetic property. Thermodynamics study indicated that the adsorption of Pb 2+ and Hg 2+ on Fe 3 O 4 @TA–Fe 3+ sorbents was spontaneous, chaotic degree decreasing and endothermic process. The present results warrant the promising application of magnetic Fe 3 O 4 @TA–Fe 3+ composites for removal of Pb 2+ and Hg 2+ from contaminated water, and this study is the first application of TA film in environmental remediation.

In the flotation of semi-soluble minerals such as calcite and fluorite, Ca2+is one of the common dissolved components influencing the collector adsorption behaviors on the mineral surfaces. However, there is very limited research focusing on how the dissolved Ca2+affects the separation of fluorite and calcite. In the study, with sodium oleate (NaOL) as a collector and tannic acid (TA) as a depressant, a flotation test, zeta potential measurement, and adsorption experiment in the presence of Ca2+were conducted. Flotation tests indicated that in the presence of Ca2+, fluorite and calcite were both significantly depressed by TA, leading to difficulty in the separation of the two minerals. It was also found that the depression effect on fluorite flotation was minimized with a high concentration of NaOL. Zeta potential measurement and the adsorption experiment results are consistent with the flotation results, revealing that it is only in the low concentration of NaOL that the flotation of fluorite was depressed by TA in the presence of Ca2+. Specifically, in the low concentration of NaOL, TA adsorbed on the fluorite surface and depressed the flotation of fluorite due to the preferential interaction between NaOL and Ca2+in the solution leading to a shortage in the effective NaOL in the solution. In the high concentration of NaOL, the adsorbed TA on the fluorite surface was displaced by the excessive NaOL in the solution; hence, the flotation of fluorite was recovered. In contrast, TA always hinders the interaction of NaOL with calcite regardless of the presence and absence of Ca2+and NaOL, hence, depressing the flotation of calcite. The study presented that a high concentration of NaOL may mitigate the negative effect of Ca2+on the fluorite surface and improve the separation of fluorite from calcite.Keywords:calcium ion;fluorite;adsorption mechanism;tannic acid

Tannic acid (TA), as a common natural catechol derivative, has been widely applied as antibacterial drug or in the construction of carriers for drug delivery with metal ions. However, unlike dopamine, another catechol derivative whose polymerized form of nanoparticles have been successfully
constructed and adopted in various biomedical fields, the development of poly-TA nanoparticles (PTANPs) is rarely reported and the optimization studies are even less. Therefore, the understanding of details and information regarding to the synthesis of PTANPs can provide insights into the
polymerization process of TA and inspire the development of other catechol derivatives based nanoscale platforms for diverse scientific applications. Herein, we used a typical sodium hydroxide (NaOH) triggered polymerization followed by hydrogen peroxide (H2O2) degradation
to prepare PTANPs. In our study, we explored the impact of temperature, weight/volume of reactants (TA, NaOH and H2O2) and reaction time (NaOH and H2O2) on the size of finally obtained PTANPs, which can give guidance and inspiration for future researches
and facilitate the studies of followers.

The effect of tannic acid (TA) binding on the thermal degradation of boscalid was studied in this work. The results revealed that TA binding has a significant impact on boscalid degradation. The degradation rate constant of bound boscalid was reduced, and its corresponding half-life was significantly prolonged compared to the free state. Four identical degradation products were detected in both states through UHPLC-Q-TOF-MS, indicating that degradation products were not affected by TA binding. Based on DFT and MS analysis, the degradation pathways of boscalid included hydroxyl substitution of chlorine atoms and cleavage of C N and C C bonds. The toxicity of B2 and B3 exceeded that of boscalid. In summary, the binding of TA and boscalid significantly affected the thermal degradation rate of boscalid while preserving the types of degradation products. This study contributed to a fundamental understanding of the degradation process of bound pesticide residues in complex food matrices.

Rapid and safe hemostasis is crucial for the survival of bleeding patients in prehospital care. It is urgent to develop high performance hemostatic material to control the massive hemorrhage in the military field and accidental trauma. In this work, an efficient protein hemostat of thrombin was immobilized onto commercial gauze, which was mediated by self-polymerization and anchoring of tannic acid (TA). Through TA treatment, the efficient immobilization of thrombin was achieved, preserving both the biological activity of thrombin and the physical properties of the dressing, including absorbency, breathability, and mechanical performance. Moreover, in the presence of TA coating and thrombin, Gau@TA/Thr could obviously shortened clotting time and enriched blood components such as plasma proteins, platelets, and red blood cells, thereby exhibiting an enhanced in vitro coagulation effect. In SD rat liver volume defect and artery transection hemorrhage models, Gau@TA/Thr still had outstanding hemostatic performance. Besides, the Gau@TA/Thr gauze had inherent antibacterial property and demonstrated excellent biocompatibility. All results suggested that Gau@TA/Thr would be a potential candidate for treating uncontrollable hemorrhage in prehospital care.

The design and development of a food preservation coating material with rapid curing and stable performance to shorten the coating process time and reduce quality changes caused by temperature fluctuations in cold chain is highly desirable in fresh meat preservation applications. In this study, a series of multi-cross-linked edible hydrogels were designed based on gelatin and k-carrageenan through the self-assembly triple-helix of gelatin and the potassium ion-mediated k-carrageenan double-helix structure. The tannic acid with phenolic hydroxyl groups was employed to enable the dynamic bond cross-linking between two polymers, endowing the composite hydrogel with rapid curing ability at low-temperature and a uniform molecular network structure. The hydrogel with a concentration of gelatin was 16% (GCBG-16) achieved the optimal combination properties, including 73.41% of elongation at break, 71.59 kJ/m 2 of toughness, 27.73% of swelling ratio, and 50.73% of DPPH· scavenging rate. The hydrogels could be rapidly washed within 30 min at 40 °C by water, as well as possessing a certain self-healing and anti-freezing capabilities. The hydrogel GCBG-16 had a great capacity for protecting meat with a E value of 50.4 and 17.53 N of shear force even placed in a 37 °C environment, which showed no significant difference (p > 0.05) compared to the initial value. Furthermore, the fresh meats with coating showed delayed central temperature increase speed after leaving from the cold chain and placed in a 37 °C environment. The research results demonstrated that the proposed hydrogel has great potential in preserving fresh meat, which can serve as a matrix material combined with other active additives for extending the shelf life of meat products.

Biomaterials capable of achieving effective sealing and hemostasis at moist wounds are in high demand in the clinical management of acute hemorrhage . Bletilla striata polysaccharide (BSP), a natural polysaccharide renowned for its hemostatic properties, holds promising applications in biomedical fields. In this study, a dual-dynamic-bonds crosslinked hydrogel was synthesized via a facile one-pot method utilizing poly(vinyl alcohol) (PVA)-borax as a matrix system, followed by the incorporation of BSP and tannic acid (TA). Chemical borate ester bonds formed around borax , coupled with multiple physical hydrogen bonds between BSP and other components, enhanced the mechanical properties and rapid self-healing capabilities. The catechol moieties in TA endowed the hydrogel with excellent adhesive strength of 30.2 kPa on the surface of wet tissues and facilitated easy removal without residue. Benefiting from the synergistic effect of TA and the preservation of the intrinsic properties of BSP, the hydrogel exhibited outstanding biocompatibility , antibacterial, and antioxidant properties. Moreover, it effectively halted acute bleeding within 31.3 s, resulting in blood loss of 15.6 % of that of the untreated group. As a superior hemostatic adhesive, the hydrogel in this study is poised to offer a novel solution for addressing future acute hemorrhage, wound healing , and other biomedical applications.

Polymer-supported MOFs membranes with high separation performances show great potentials in industrial purification of H 2 . The key to growing defect-free and adherent MOFs layers on polymer substrates is the abundant and uniformly distributed nucleation sites on the surface of polymer substrates. Therefore, in this work, a mixed-matrix polyacrylonitrile (PAN) substrate with ZIF-8-rich seed layer (ZS-PAN) was constructed by gravity induced deposition and gradient distribution of ZIF-8 before phase inversion, then under the assistance of Tannic acid (TA), the dense and defect-free ZIF-8 membrane on flexible polymer substrate was fabricated followed by the secondary growth of ZIF-8. The EDS and SEM results of the membrane cross-section confirm the gradient distribution of ZIF-8 seeds, and the resultant membranes are defect-free. The H 2 permeance of TA-ZIF-8/ZS-PAN membrane is 953.66 GPU, and the H 2 /CO 2 selectivity is 12.09, which is 80.17 % higher than that of ZIF-8/ZS-PAN membrane without TA, exceeding the Robeson upper bound in 2008. This improved H 2 separation performance is derived from the following reasons. First, gravity-induced ZIF-8 seed deposition constructs a ZIF-8-rich seed layer on the mixed-matrix polymer substrate, which increases the nucleation sites. Second, the introduction of TA during the secondary growth process further increases the nucleation sites by hydroxyl-chelated zinc ions, both of which contribute to the dense ZIF-8 membrane. At the same time, the hydroxyl group in TA is CO 2 -philic, which can delay CO 2 permeation and improve the H 2 /CO 2 separation performance by physically adsorbing CO 2 . The proposed mixed-matrix substrate by gravity induced deposition of MOFs provides a novel strategy for constructing defect-free and flexible MOFs membrane.

The objective of this study was to investigate the interaction between tannic acid (TA) and konjac glucomannan (KGM) with different molecular weight at different pHs,temperatures and urea concentration. The different molecular weight of KGM without change in primary structure were obtained by ultrasonic treatment. Turbidity titration showed that TA/KGM complexes could form at lower pH. The dynamic light scattering (DLS) and transmission electron microscopy (TEM) results indicated that the TA/KGM complexes assembled into large and uniform colloidal particles and would lead to precipitate with the increase of TA/KGM weight ratio. Isothermal titration calorimetry (ITC) results further revealed two-step binding behavior: the first stage corresponded to soluble complex formation, while the second stage represented aggregation between complexes. When the molecular increased, the transition of TA/KGM mass ratio between stage 1 and stage 2 changed from 3.5 to 3.0. KGM of higher molecular weight needed to bind more TA to move to the next stage. When the pH was 7 at 25 °C, the pH was 3.8 at 40 °C or urea addition, the ITC signal was completely abolished, the formation of complexes between KGM and TA was shown to be highly dependent on pH, temperature, urea concentration, suggesting the main driving force of TA-KGM complexes formation was hydrogen bond.

Three-dimensional bioprinting has emerged as a promising technique for creating personalized scaffolds. However, traditional extrusion-based methods face challenges with resolution and structural fidelity. This study aims to introduce a hybrid bioink, combining N-acryloylglycinamide (NAGA) with a rheology modifier to enhance both the stability and precision of printed designs. Additionally, we implemented a controlled immersion shrinkage process to further enhance the resolution. Immersing the printed structures in a 55% w/v tannic acid (TA) solution, the average grid area was reduced to 35.21% of its original size, significantly improving resolution. This treatment also boosted the antioxidant properties of the hydrogel, achieving a 90.5% ABTS removal rate. The hydrogel demonstrated excellent cytocompatibility, enhanced cell proliferation, and maintained high-resolution printability and antioxidant properties, making it a promising biomaterial for soft tissue regeneration.

It is necessary to prepare a nanofiltration membrane with high permeation flux that can be used in the field of organic solvents. Gel membranes have a high solvent permeation flux, but their chained macromolecular structure is often unstable. In this study, tannic acid-bridged sodium alginate (TA x -Ca/FeSA) organic solvent nanofiltration (OSN) membranes were prepared by the phase transition method using aqueous Ca 2+ and Fe 3+ solutions as cross-linking agents. TA can interact with SA through hydrogen bonding hydrophobic bonding and other interactions to form an interpenetrating three-dimensional network structure. Compared with Ca/FeSA membrane, the average pore size of TA 0.125 -Ca/FeSA membrane was reduced from 1.03 nm to 0.74 nm, and the porosity was increased from 47.62 to 59.2 %. In addition, the TA 0.125 -Ca/FeSA membrane has the characteristics of a negative charge, super hydrophilicity, and high mechanical properties, exhibits a high permeation flux of 48.97 L·m −2 ·h −1 ·bar −1 with a rejection of 96.25 % for Congo red ethanol solution, has excellent solvent resistance, stain resistance, and self-cleaning ability. The TA 0.125 -Ca/FeSA membrane was demonstrated to have great potential for application in the fields of purification and solvent recovery.
