Wearing a compression garment (CG) can effectively prevent and treat hypertrophic scars (HS), but the surface of CG is prone to bacterial growth. Therefore, it is particularly important to carry out antibacterial finishing on compression garment fabric (CGF). In order to achieve the purpose of synergistic antibacterial action, improving bacteriostatic rate, and enhancing biological safety, this study prepared a composite material of MXene (Ti3C2Tx), chitosan, and amino silane coupling agent (3-aminopropyl)triethoxysilane (APTES) and its antibacterial CGF. The binding mechanism between the antibacterial composite material and the CGF was explored, and the bacteriostatic rates, wearing properties, and wash fastness of the antibacterial CGF were studied. Results showed that Ti3C2Tx, chitosan, and APTES were covalently bonded to the CGF, achieving synergistic antibacterial effects. The antibacterial CGF without washing showed a bacteriostatic rate of 99.9% against both Gram-negative bacteria Esherichia coli (E. coli, AATCC 6538) and Gram-positive bacteria Staphylococcus aureus (S. aureus, AATCC 25922), with washing fastness reaching grade AA. Additionally, the comfort of the antibacterial finishing fabric was affected to a certain extent in terms of flexural rigidity and air permeability, but overall, the wearability of the antibacterial CGF also met the daily wearing needs of patients.

Surface heparinization is considered an efficient strategy to improve the hemocompatibility of polymeric membranes. We aim to realize the feasible surface heparinization of polylactide (PLA) membranes by means of a colourless 3-aminopropyltriethoxysilane (APTES) functionalized platform. APTES conjugated heparin (Hep–APTES) was first synthesized through the amidation reaction and then anchored onto PLA membrane via surface attachment, condensation, multilayer formation. The surface chemistry was confirmed by Fourier Transform Infrared-Attenuated Total Reflectance (ATR-FTIR) and X-ray Photoelectron Spectroscopy (XPS). The influences of heparinization time and micro-swelling agent (DMAc) on the heparin density, stability and sustained-release were investigated. The hydrophilicity, flux and morphology were also studied by contact angle, pure water flux and Scanning Electron Microscope (SEM). The hemocompatibility was evaluated by the activated partial thromboplastin time (APTT), prothrombin time (PT), the content of fibrinogen (FIB), platelet and Bovine Serum Albumin (BSA) adsorption respectively. All results demonstrated that APTES assisted surface heparinization provided a feasible and efficient strategy to improve the hemocompatibility of PLA membrane.

Silver-phosphate/graphene oxide/APTES (Ag 3 PO 4 /GO/APTES) composite materials modified by 3-aminopropyltriethoxysilane (APTES) were incorporated into polyvinylidene fluoride (PVDF) membrane to obtain light catalytic membrane. The structure and morphology of Ag 3 PO 4 /GO/APTES were characterized by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and thermogravimetric analyzer (TGA). Next, the morphology structure and roughness of Ag 3 PO 4 /GO/APTES/PVDF membrane were studied using SEM and Atomic force microscopy (AFM). The hydrophilicity and water flux of blended membranes were enhanced by the presence of a large number of hydrophilic groups on the surfaces of GO and APTES. Using Bovine serum albumin (BSA) solution as a pollution model, the multi-cycle anti-organic pollution ability of composite membranes was explored, and the anti-pollution performance was improved. The results showed that with the increase of Ag 3 PO 4 /GO/APTES content in the composite membrane, the rejection rate of dyes increases significantly. The enhanced photocatalytic degradation can be attributed to the presence of RGO which facilitates electron mediation and shuttle. This work provide a method for the efficient removal of dyes from wastewater.

Development of effective iodine capture materials and techniques is crucial for addressing the diverse applications of iodine and its significance in various contexts, including nuclear pollution control. This study presents the creation of a new 3-Aminopropyltriethoxysilane (APTES)-modified boron nitride (BN) aerogel designed for effective iodine capture. The internal structural units of BN aerogel , specifically the one-dimensional BN fibers, have been successfully functionalized with amine groups, resulting in the formation of an amine-rich SiO x capping layer on the surface of these fibers. The APTES modification not only establishes a stable connection within the internal BN fibers network but also imparts the material with a significant number of iodine capture sites. The resulting aerogel demonstrates an impressive iodine vapor capture capacity of 313.64 wt% at 350 K and atmospheric pressure, and up to 1028.96 mg/g in iodine/n-hexane solution, surpassing the capabilities of pure BN aerogel and most existing iodine capture materials. The excellent iodine capture performance of APTES-modified BN aerogel suggests its promising potential for future applications in iodine capture.

To eliminate the interfacial defects between polymeric matrix and inorganic fillers in hybrid membranes, various strategies have been proposed by modifying membrane materials or optimizing membrane formation process. In this work, a ternary cross-linked PVA-APTES-ZIF-90 (PVA, poly(vinyl alcohol); APTES, 3-aminopropyltriethoxysilane; ZIF-90, zeolitic imidazolate framework-90) membrane was developed to eliminate interfacial defects between PVA and ZIF-90 for enhanced ethanol dehydration performance, where APTES served as a covalently linked bridge to cross-link PVA and ZIF-90 simultaneously. The morphologies and physicochemical properties of the resultant membranes were characterized by various characterization techniques. Moreover, we also explored the effects of [ZIF-90]/[APTES] mole ratio and [ZIF-90]/[APTES] loading on the separation performance of the trinity membranes. The results indicated that ZIF-90 particles showed better dispersion and compatibility in PVA-APTES-ZIF-90 trinity membranes than in PVA/ZIF-90 hybrid membrane, attributed to the ternary cross-linking among PVA, APTES, and ZIF-90. Compared with pristine PVA membrane, PVA-APTES-ZIF-90 trinity membranes showed stronger anti-swelling and mechanical properties, as well as more excellent separation performance, which resulted from the incorporation of cross-linker APTES and ZIF-90 particles. The separation factor of the optimal PVA-APTES-ZIF-90 trinity membrane was improved by 215.4%, up to 552, accompanied by a total flux of 82 g/m 2 h. Ternary cross-linking among cross-linker, inorganic filler, and polymeric chain is therefore believed to be a feasible strategy in preparing polymeric-based hybrid membranes with high separation performance.

Detection of high-risk human papillomavirus (HR-HPV) is critical for early warning and accurate screening of cervical disease in women. Electrochemical biosensors offer a promising analytical strategy that can circumvent the structural complexity of traditional optical components found in current bioassays. In this work, an innovative electrochemical biosensor for HPV-16 detection was developed, utilizing advanced nanomaterial technology and optimized DNA probe grafting processes. The self-assembled composite nanofilm was optimized by conducting an orthogonal analysis. The nanofilm exploited the unique advantages and outstanding performance of (3-aminopropyl)triethoxysilane (APTES) and carbon quantum dots (CQDs), which act as a “molecular bridge” between the biosensing interface and the electrode substrate. The electroactive molecule [Ru(NH 3 ) 6 ] 3+ facilitated the highly sensitive signaling of the target DNA by interacting with the double-stranded DNA. Under optimal conditions, the developed electrochemical DNA biosensor exhibited high sensitivity in detecting HPV-16, with a limit of detection (LOD) of 0.73 fM, which showed exceptional potential to be used in widespread point-of-care (PoC) screening programs, opening up new opportunities for various applications.

FeNi powders were insulated with APTES by solution method and solidification method, respectively. Different coating mechanisms have been systematically studied according to analysis on microstructure, surface charge state, thermal stability of magnetic powders and magnetic properties of corresponding soft magnetic composites (SMCs). It was found that a slight amount of polysiloxane and amorphous silica would be deposited on FeNi powders in solution method, resulting in an ultra-thin insulation layer. In contrast, continuously increasing concentration of polysiloxane in reaction zone gives rise to a thick and smooth SiO 2 layer in solidification method. Owing to unique growth mechanisms of solidification method, it is easy to control the thickness of SiO 2 layer by adjusting the concentration of APTES, which is in favor of improving insulation quality. Accordingly, FeNi SMCs prepared in solidification method own much higher resistivity, lower μ ″ and lower tan δ (particularly at high frequency), compared with samples obtained by solution method with the same volume of APTES. Besides, increasing volume of APTES in solidification method leads to the decrease of both μ′ and μ″ . This work may not only provide novel insights into APTES-based insulation process, but also offer powerful technique for fabricating high-frequency SMCs.

Membrane based separation technology has great prospects in the treatment of oily wastewater, which involves serious environmental and health concern. In the present investigation, 3-aminopropyltriethoxysilane (APTES) was used to modify MXene nanosheets and amine functionalized carbon nanotubes (ACNTs) was used to control the layer spacing of MXene followed by the fabrication of a series of APTES/MXene-ACNTs composite membranes supported on cellulose acetate (CA) by vacuum filtration. The surface morphology analysis by scanning electron microscope (SEM) and atomic force microscopy (AFM) revealed that, the composite membranes exhibited excellent hydrophilicity as well as high efficiency in oil/water emulsion separation. The rejection ratios of composite membranes for lubricating oil emulsion and vegetable oil emulsion were found to be more than 99%. Compared to the pure MXene membrane M1 (500.7 L·m −2 ·h −1 ·bar −1 ), the pure water flux of the best modified membrane APTES/MXene-ACNTs/CA (M4) reaches up to 2892.8 L·m −2 ·h −1 ·bar −1 . Moreover, the modified membrane shows good anti-fouling and anti-swelling characteristics even after several cyclic consecutive cycles. This work demonstrates a new horizon in the applications of two-dimensional membrane materials.

Introduction To develop a fluorescent adhesive by incorporating 3-aminopropyltriethoxysilane (APTES)-modified ZnO quantum dots (A-ZnOQDs) and to evaluate its bond strength, rheological properties, cytocompatibility, and removal performance. Methods ZnOQDs were modified with APTES and blended with commercial orthodontic adhesive to construct the fluorescent adhesive, which was divided into four groups (0, 2, 4, and 6 wt.%). Shear bond strength (SBS) was measured with a universal testing machine. Rheological properties were evaluated through a dynamic shear rheometer (DSR) test. Cytocompatibility was assessed with a CCK-8 kit. Bracket bonding and debonding procedures were performed on a head simulator. Adhesive removal effectiveness during bonding and debonding procedures was assessed. Results There was no significant difference in SBS among four groups (0%: 10.06 ± 4.81 MPa, 2%: 8.98 ± 3.70 MPa, 4%: 10.88 ± 5.12 MPa, 6%: 8.09 ± 3.43 MPa, p > 0.05). DSR displayed that the rheological curves of group-2% and group-4% were close to that of group-0%. CCK-8 assay indicated cell vitality did not differ among group-0%, group-2%, and group-4% ( p > 0.05). Group-4% showed less excess adhesive area (0%: 1.81 ± 1.58 mm 2 , 4%: 0.95 ± 1.33 mm 2 , p = 0.0465), less remnant adhesive area (0%: 0.73 ± 0.79 mm 2 , 4%: 0.07 ± 0.21 mm 2 , p = 0.0002), more time taken in removing excess adhesive (0%: 40.76 ± 6.44 s, 4%: 47.19 ± 8.40 s, p = 0.0046), and similar time taken in removing remnant adhesive (0%: 40.04 ± 10.05 s, 4%: 43.54 ± 10.18 s, p = 0.2365). Conclusions Fluorescent orthodontic adhesive containing 4 wt.% of A-ZnOQDs with reliable SBS, rheological properties, and cytocompatibility was successfully constructed, with proof that it can be recognised and removed efficiently.

In order to improve the tribological properties of titanium substrate, self-assembly technique was used to prepare a graphene-silane coating: RGO-APTES coating on titanium substrate. The γ-aminopropyltriethoxysilane (APTES) was used to prepare a self-assembled APTES coating as a function of adhesive interlayer, aiming to improve the assembly efficient for graphene coating. The influence of that interlayer on the assembly and tribological properties of graphene coatings on titanium substrate was investigated. Morphology, thickness, chemical characteristic and tribological tests were utilized to investigate the assembly process and tribological properties of coatings. The results show that: (1) the pH values of APTES aqueous solution plays an important role in the molecule orientation of the APTES interlayer, and thus the properties of graphene coating is influenced. When pH is approximately 8.5, the molecule orientation of the interlayer is consistent, so that it has improved adsorption effect on graphene sheets and the graphene coating is uniformly distributed and well-covered; (2) the thickness influences the tribological properties of graphene-APTES coating -- single layered APTES interlayer provides a stronger interlayer strength. The obtained RGO-APTES2 samples have novel friction reducing and wear resisting properties, and can be applied on the surface of titanium substrate as lubricating coating.

The development of high-performance hydrogen separation membranes is a crucial step in the advancement of sustainable energy technologies and the achievement of carbon neutrality. In this study, zeolitic imidazolate framework-8 (ZIF-8) membranes with an ultra-high selectivity for hydrogen over carbon dioxide were successfully synthesised on polydopamine/3-aminopropyltriethoxysilane (PDA/APTES) modified Al 2 O 3 supports. The interfacial layer exhibited excellent adhesion and a high density of functional groups, which served as nucleation sites for the growth of ZIF-8 crystals. The resulting membranes exhibited a dense and defect-free structure, achieved through an optimised 12 h in-situ growth process. The membranes exhibited excellent gas separation performance, with hydrogen(H 2 ) permeance reaching 14 × 10 −7 mol·Pa −1 ·m −2 ·s −1 and ideal selectivities of 20.3, 22.1, and 26.8 for H 2 /CO 2 , H 2 /N 2, and H 2 /CH 4 , respectively, at 25 °C and 0.2 MPa. In comparison with the ZIF-8 membrane that was synthesised on a pure PDA modified layer, the H 2 permeance increased by 14.8 %. Notably, the selectivity for H 2 /CO 2 increased by almost threefold. Moreover, long-term stability tests demonstrated the durability and robustness of the ZIF-8 membranes under operational conditions.

In recent years, all-inorganic halide perovskite quantum dots (IPQDs) have received a lot of attention as a new fluorescent material with excellent fluorescence properties. But their instability in polar solvents is the major factor that obstructs their applications in analysis. In this work, a novel fluorescent sensor was simply synthesized by room temperature synthesis for the detection of tetracycline (TC) in highly polar ethanol. At room temperature, a silicon layer was easily modified by in situ hydrolysis of 3-aminopropyltriethoxysilane (APTES) on the surface of IPQDs to synthesize a new type of fluorescent sensor without adding water or an initiator, which can be stably present in ethanol. The novel method has shown high selectivity and sensitivity to TC in ethanol, and the detection limit can even reach 76 nM. The mechanism of fluorescence quenching is mainly the electron transfer between TC and IPQDs. Furthermore, the sensor was successfully applied to the detection of trace TC in actual samples. Our research has laid the foundation for improving the stability of perovskite quantum dots and their development in the field of analytical chemistry.
