Enrofloxacin residues in foods pose potential risks to food safety and public health, creating demand for rapid, sensitive, and matrix-compatible screening methods. All-inorganic CsPbBr3quantum dots (QDs) are promising fluorescent probes because of their strong photoluminescence, but their poor stability in polar media greatly restricts their practical use in food analysis. Herein, ZIF-8-confined and APTES-passivated CsPbBr3QDs were developed as an ethanol-compatible fluorescent sensor for enrofloxacin detection in foods. Unlike reported CsPbBr3@ZIF-8 systems mainly used for metal-ion sensing in aqueous media, this work integrates ZIF-8-confined in-situ growth with APTES-assisted silane passivation to improve the stability and applicability of CsPbBr3QDs in ethanol-based food extracts. ZIF-8 provided a confined microenvironment, while the APTES-derived silane layer further enhanced fluorescence stability. The sensor exhibited a distinct turn-off fluorescence response toward enrofloxacin, with a linear range of 0.1–25.0 mg·L−1and a limit of detection of 0.058 mg·L−1, mainly attributed to electron transfer with CsPbBr3@ZIF-8. The method was successfully applied to honey, milk, fish, and shrimp samples, achieving recoveries of 85.2–106.8%. Results obtained for aquatic products showed no significant difference from HPLC analysis (p> 0.05), demonstrating the potential of this sensor for rapid enrofloxacin residue screening in complex food matrices.

A new adsorbent, 3-aminopropyltriethoxysilane (APTES) modified silica achieves 98.7% of phospholipid removal and 92.3% of total phenol retention for degumming of crude rapeseed oil at 45 °C for 30 min with dosage of 1% wt. The key indicators of oil quality for APTES-SiO 2 degummed sample improved significantly, including peroxide value, acid value, color, and clarity. Moreover, E -nose and two-dimensional gas chromatography–mass spectrometry analysis results revealed that APTES-SiO 2 degummed oil had little change of the flavor. FTIR results suggested no trace of APTES molecule residence in the degummed oil, which guaranteed the oil safety. Combined with the correlations of zeta potential, XPS results, and degumming performance, the adsorption mechanism revealed that the hydrophobic surface of APTES-SiO 2 adsorbent worked synergistically with protonated amino groups to promote dephosphorization rate. Our findings provided high interest for rational design and preparation of highly dispersed and efficient adsorbent for degumming of crude oil.

Plastic pollution and the treatment of oily wastewater have become significant challenges in the field of environmental protection. This study presents a method for fabricating electrospun membranes from waste polyethylene terephthalate (PET) beverage bottles, which are surface-modified by co -depositing tea polyphenols (TP), 3-aminopropyltriethoxysilane (APTES), and tetraethoxysilane (TEOS). The resulting superhydrophilic membrane, denoted as PET-T-100, exhibits excellent mechanical properties and structural stability due to the optimization of precursor solution composition and electrospinning parameters. The modified membrane shows a water contact angle of 0° in air and an underwater oil contact angle of 161°, demonstrating outstanding wettability. In oil-water separation experiments, PET-T-100 achieves a separation efficiency of over 99.5 % for various oil-water mixtures, and over 98 % for emulsions, maintaining stable wettability and separation performance even in harsh acidic, alkaline, and saline environments. This study provides an efficient and environmentally friendly approach for the high-value utilization of waste PET and offers a novel strategy for the development of high-performance oil-water separation membranes and environmental remediation technologies.

Two-dimensional Ti 3 C 2 T x MXene, with a large specific surface area, high chemical stability and excellent barrier properties, has become a promising of anti-corrosion filler in organic coatings. However, the poor dispersion and compatibility in organic coatings restrict its efficient application. To this end, L-histidine (L-His) corrosion inhibitor was grafted on the 3-aminopropyl triethoxysilane (APTES) functionalized Ti 3 C 2 T x MXene surface, under the electrostatic attraction between the carboxylate and protonated aminopropyl groups. The obtained APTES-Ti 3 C 2 T x MXene@L-His cannot only accelerate the dispersion of Ti 3 C 2 T x MXene filler, but also greatly promote the anti-corrosion property and service lifetime of coatings through combining the physical shielding effect of MXene laminate structure with active anti-corrosion function of L-His corrosion inhibitor. Results show that amino-functionalized Ti 3 C 2 T x MXene can maintain homogeneous in epoxy resin for 300 h, enhancing its dispersion in epoxy coating. Moreover, APTES-Ti 3 C 2 T x MXene@L-His composite can achieve the continuous release of L-His for 3000 min, and additional acid-base dual response property, the releasing rate of L-His is significantly accelerated in acidic or alkaline solutions. The total loading amount of L-His in APTES-Ti 3 C 2 T x MXene@L-His composite is about 3 %. Furthermore, the practical composite coating containing APTES-Ti 3 C 2 T x MXene@L-His also exhibits the excellent anti-corrosion and certain self-healing properties, such as its |Z 0.01 Hz| value remains above 10 10 Ω·cm 2 during the 40 d immersing in 3.5 NaCl solution, which is 3 orders of magnitude higher than that of pure epoxy coating. This work extends the great significance for Ti 3 C 2 T x MXene based composite coatings application of in the field of anti-corrosion.

It is of great significance to sort specific types of cells through a fast and efficient technology in biomedical research and clinical applications. In this study, commercial hollow glass beads were modified with 3-aminopropyltriethoxysilane (ATPES) and hyaluronic acid (HA) sequentially, which can capture HeLa cells with nearly 100% efficiency within 10 min. The beads can specifically recognize and sort HeLa cells from a cell coculture of HeLa and L-929 depending on their strong buoyancy and good affinity with cancer cells. The job provides a facile, quick and low-cost cell sorting method, which has potential application in the fields of specific and efficient cell isolation.

The interfacial bond between carbon fibers (CF) and resin matrix determines the mechanical properties of carbon fiber-reinforced composites. Therefore, surface modification of CF to enhance the interfacial bonding between them is essential. In this paper, quercetin (QU) and 3-aminopropyltriethoxysilane (APTES) were used as raw materials to improve the interfacial properties of CF by co-depositing on the CF surface. QU and APTES undergo a Michael addition or Schiff base reaction under alkaline conditions, resulting in the substance with adhesive properties, which can be uniformly coated on the inert surface of CF. Additionally, the coating introduces a large number of amino groups on the CF surface, which promotes the chemical interaction between the CF and the epoxy resin matrix. The interlayer shear strength (ILSS), flexural modulus, and flexural strength of the composites were enhanced after co-deposition. A new idea for green modification of the CF surface was provided.

Secondary reactions of surface coating are of great importance and have drawn great attentions, since it can make the coating as a versatile platform for different uses via tailoring surface properties. A good example is the polydopamine (PDA) coating which has been widely used for preparation of various functional materials owing to its secondary reactions. In our recent study, we have developed hierarchical tannic acid (TA)-aminopropyltriethoxysilane (APTES) coating with distinct layer-nanospheres structure. Herein, the secondary reactions of the TA-APTES coating has been investigated in detail. And for the first time, various (TA-APTES)-based functional materials including superhydrophobic , adsorbent, and catalytic materials have been prepared for oil/water separation, dye adsorption, and 4-nitrophenol reduction, respectively. Significantly, under the same conditions, the performance of the (TA-APTES)-based functional materials is much better than that of the PDA-based materials: (a) The adsorptive capacity of the (TA-APTES)-based adsorbent toward rose bengal, methyl bule, orange G, and amaranthus red is 80.1%, 96.2%, 86.1%, and 98.6% higher than that of the PDA-based adsorbent, respectively; (b) The (TA-APTES)-based catalytic material can reduce about 98% of 4-NP in 10 min, while the PDA-based material can only reduce 60% of 4-NP under the same conditions; (c) After reacting with octadecyltrimethoxysilane, the TA-APTES coating can be directly transformed into superhydrophobic coating for oil/water separation, while the PDA coating is only hydrophobic and cannot separate oil/water mixture. The reasons for the significantly improved performance of the (TA-APTES)-based materials have been revealed. Our findings demonstrate that the TA-APTES coating can act as an outstanding platform for preparation of various functional materials with preferable performance, and the TA-APTES coating will be a promising substitute for PDA coatings.

Modified calcium saturated montmorillonite (Mt) was prepared at different 3-aminopropyltriethoxysilane (APTES) loadings through grafting. The as-products were characterized by XRD, FTIR and elemental analysis. Surface analysis such as acidity was examined at different H+ concentrations, showing that the release of OH− from the modified samples increased in the following order: APTES4.0CEC–Mt > APTES3.0CEC–Mt > APTES2.0CEC–Mt > APTES1.0CEC–Mt. Batch experiments were conducted and different conditions (pH, temperature and co-existing ions) were used to evaluate the adsorption capacity of the modified samples. The study developed a new way to confirm the mechanism, which indicated that ligand adsorption was the dominant sorption mechanism for Sr(II) uptake onto APTES–Mts. In general, APTES grafted montmorillonite possessed a higher efficiency of Sr(II) uptake and showed great potential for Sr(II)-rich wastewater treatment.

Tannic acid(TA)-aminopropyltriethoxysilane(APTES) coating possesses hierarchical structure and superhydrophilicity, and can be facilely coated on various porous membranes for oil-water separation. However, the TA-APTES coating will lose its superhydrophilicity and underwater superoleophobicity after being exposed to the air for more than one month. Besides, TA-APTES coating on membrane surface decomposes when the coating is immersed in acidic solution (pH ≤ 3) or alkaline solution (pH ≥ 12). In this study, the reasons for the instability of TA-APTES coating have been studied, and an effective strategy for significantly improving the stability of the coating has been developed via simple treatment with ferric ions. The coordination effect between ferric ions and the TA-APTES coating can not only restrain the oxidation of the phenolic hydroxyl groups, but also decrease the electrostatic repulsion and enhance the interactions between the chain segments. The resultant (TA-APTES)-Fe(III) coating possesses long-term superhydrophilicity and excellent acid-base resistance property, while the distinct and hierarchical structure of the TA-APTES coating can be reserved. Thanks to the outstanding stability of (TA-APTES)-Fe(III) coating, the PVDF-(TA-APTES)-Fe(III) membrane can maintain its outstanding anti-oil-fouling property and good oil/water separation performance even it is being exposed in air for one month or being immersed in strong acidic or alkaline solutions for 48 h, which is much better than the pristine PVDF-(TA-APTES) membrane. This study will accelerate the practical application of TA-APTES coating.

Plant polyphenol-inspired surface modification of membranes is helpful for oil–water separation. However, the preparation of this coating is time-consuming. Herein, we introduce a rapid synthesis of the TA-APTES coating by the addition of sodium periodate (SP). The surface chemical composition and morphology of the resultant TA-APTES hybrid coatings were characterized using SEM, ATR-FTIR, and XPS. The hydrophilicity and membrane performance were investigated by the water contact angle, pure water permeability, and oil rejection for an isooctane-in-water emulsion. The experimental findings revealed that the optimal microfiltration (MF) membrane (MF-TA-APTES-SP-0.05) displayed exceptional hydrophilicity and water permeability (9558 L m–2 h–1 bar–1). The membrane realized highly efficient separation with a permeability (4117 L m–2 h–1 bar–1) and rejection of oils (>99%). Furthermore, it possessed outstanding chemical stability and maintained underwater superoleophobicity even after exposure to harsh conditions. This simple and rapid strategy of developing hydrophilic coatings as a modifier for the poly(vinylidene fluoride) membranes has potential applications in oil–water separation and wastewater treatment.

In our previous work, we have developed tannic acid (TA)-3-aminopropyltriethoxysilane (APTES) coating (TA-APTES coating) for membrane surface modification, which has several distinct advantages: suitable for various membranes, hierarchical structures, mild conditions, etc. In this work, we developed (TA-APTES)Plus coating, which exhibits much better performance than our previous TA-APTES coating: (1) Much faster: The membrane modification process based on our (TA-APTES)plus coating only needs 40 min, while our previous TA-APTES coating needs 12 h; (2) Much greener: The (TA-APTES)Plus coating is prepared in pure water system, without Tris-HCl buffer solution , without oxidants such as H 2 O 2 or KIO 4 ; (3) More stable: The (TA-APTES)Plus coating can remain superhydrophilic even after 30 days, which cannot be achieved by our previous TA-APTES coating. Moreover, the (TA-APTES)Plus coating reserves the advantages of our previous TA-APTES coating, such as universality and distinct hierarchical structures. Take polypropylene (PP) microfiltration membrane as an example, the PP membrane modified by (TA-APTES)Plus not only possesses ultra-high pure water flux (11,990 L m −2 h −1 bar −1 ) and high separation efficiency (>99.8%) of oil-in-water emulsion, but also exhibits excellent stability. Considering its much better performance, the (TA-APTES)Plus coating may become a more powerful tool for membrane modification toward oil/water separation.

The weather resistance capability of insulating materials, i.e. surface performance including hydrophobicity, mechanical and electrical strength under diverse weather conditions, is considered of critical importance for high-voltage devices working outdoors. In this study, atmospheric pressure plasma jet with Ar/Hexamethyldisiloxane (HMDSO) assisted by γ-Aminopropyltriethoxysilane (APTES) and oxygen (O 2 ) addition is employed to deposit a robust insulating film with good weather resistance capability on the surface of Polymethylmethacrylate (PMMA). The gas flow rates of Si-containing precursors (HMDSO/APTES) and auxiliary gas (O 2 ) are varied to elucidate the correlation between precursor ratio and film performances. The mechanism for robust film deposition is explored by investigating reactions of active particles deduced from discharge characteristics, surface physical morphology and chemical composition variations. The results indicate that APTES plays a pivotal role in the enhancement of the film mechanical strength, while O 2 can further improve both mechanical and electrical performances. A robust superhydrophobic film is deposited, inhibiting the reduction in water contact angle by 81.6 % after the tape peel test compared with the film deposited by Ar/HMDSO system, and the flashover voltage is increased by 38.2 % with the optimal HMDSO/APTES/O 2 ratio of 7:5:1. The simultaneous improvements of the film hydrophobic, mechanical and electrical performances are contributed by crosslinking of silicone deposits and the introduction of -NH₂ groups. The weather resistance capability of the insulating material is effectively enhanced, providing guidance for outdoor insulation applications.
