The surface stress–based transduction enabled by antibody functionalization has emerged as a promising paradigm for label-free biosensor development. However, the inherent limitations of conventional detection methods (e.g., high cost, complex modification, insufficient sensitivity) and the challenge of achieving high-throughput analysis hinder their practical clinical application. Herein, a high-throughput label-free biosensor array based on multi-component integration of gold nanoparticles (AuNPs), polydimethylsiloxane (PDMS) membrane, and conductive silver paste is proposed for sensitive and specific detection of alpha-fetoprotein (AFP), a pivotal biomarker for hepatocellular carcinoma (HCC). The specific immunoreaction between immobilized anti-AFP antibodies and target AFP induces compressive surface stress, which triggers PDMS membrane deformation and regulates the electrical resistance of the AuNP conductive layer, realizing the stress-electric coupling transduction. Systematic optimization of antibody surface density (50 μg/mL) and AuNP layer thickness (0.67 μm) maximizes antigen capture efficiency and mechano-electrical transduction performance. The proof-of-concept application for AFP detection demonstrates remarkable analytical performance: a linear detection range of 0–50 ng/mL, a low limit of detection (LOD) of 0.225 ng/mL, high specificity against interfering biomolecules. Furthermore, accurate detection of AFP in clinical serum samples (relative error < 5.05%, RSD < 2.97%) confirms its practical applicability. All these results indicate that the integrated design and parameter optimization of the AuNP-PDMS-based biosensor array enhance the performance of surface stress biosensors, providing a cost-effective platform for the sensitive detection of clinical cancer biomarkers.

Owing to the numerous hazards associated with oily wastewater, superhydrophobic materials desirable for oil-water separation have attracted considerable attention. Herein, a double hydrophobic polyhedral oligomeric silsesquioxane-polystyrene (POSS-(PS) 8 ) star-shaped copolymer was synthesized by atom transfer radical polymerization (ATRP). The superhydrophobic coating for oil-water separation was prepared by PDMS anchoring POSS-(PS) 8 on the surface of cotton fabric (CF) through nonsolvent induced assembly. The influence of POSS-(PS) 8 and PDMS solution concentration on the optical properties and durability of result superhydrophobic coating were evaluated. Notably, the optimal PDMS dosage endows the superhydrophobic coating with both high optical transmittance (88.4 ± 0.3%) and high haze (87.6 ± 0.6%). Furthermore, the superhydrophobic cotton fabric (SCF) was investigated revealing it has the ability to efficiently separate various oil-water mixtures due to its superhydrophobicity, and maintain good separation efficiency even after 30 cycles. This work will provide a feasible strategy for potential application of the low cost and environmentally friendly SCF in oil-water separation.

With the increasingly severe electromagnetic wave (EMW) pollution, developing comfortable and durable multifunctional electromagnetic wave absorption (EWA) textiles has become an urgent need. In this work, a functional textile integrating superhydrophobicity, EWA performance, and photothermal property was successfully fabricated via the atomized spraying method. A ZIF-8/PPy/ZIF-8 (ZPZ) sandwich structure was constructed on polyester (PET) fabric, followed by surface modification with poly(dimethylsiloxane) (PDMS). Benefiting from the synergistic effect of the ZPZ structure, the middle PPy layer contributes to dielectric loss. ZIF-8 constructs a macroscopic multilevel scattering framework to optimize impedance matching, while it provides high-density polarization sites to enhance dielectric loss, which achieves broadband strong absorption. At a thickness of 3.4 mm, the minimum reflection loss (RLmin) is −54.55 dB and the maximum effective absorption bandwidth (EABmax) is 7.92 GHz. PDMS can not only adjust the complex impedance coefficient for electromagnetic wave absorption, but also offers a self-cleaning property and durable superhydrophobicity to protect the stability of the internal structure, capable of withstanding repeated washing, abrasion, and chemical erosion. Additionally, the conjugated molecular structure in PPy features abundant delocalized π electrons and a narrow band gap. PDMS-ZPZ-PET fabric demonstrates highly efficient and stable photothermal performance over multiple cycles. This simple and effective preparation method offers a research direction for the advancement of high-performance EWA textiles.

With the escalating environmental challenges posed by CO 2 emissions, particularly the greenhouse effect, the development of efficient CO 2 utilization and storage technologies have become critically important. The mixed matrix membranes (MMMs) have emerged as promising candidates for gas separation due to their superior permeability and selectivity. However, practical applications are often hindered by issues such as nanoparticle agglomeration and poor compatibility between fillers and polymer matrices. In this study, a pre-assembly strategy was proposed. Through 2-methylimidazole (Hmim) served as a molecular bridge connecting the ZIF-67 with the polydimethylsiloxane-poly(ethylene oxide) (PDMS-PEO) block copolymer, the ternary ZIF-67-Hmim-PDMS-PEO nanofluid was constructed, which was subsequently blended with Pebax1657 to fabricate high-performance MMMs for CO 2 separation. Comprehensive characterization of the ZIF-67-Hmim-PDMS-PEO/Pebax1657 MMMs was conducted using SEM, XRD, FTIR, TGA, and DSC techniques. The results demonstrated that the ternary blending strategy involving ZIF-67, Hmim, and PDMS-PEO not only significantly enhanced the dispersion stability of ZIF-67 nanoparticles but also improved their compatibility with the polymer matrix. Remarkably, the incorporation of ZIF-67-Hmim-PDMS-PEO nanofluid led to substantial improvements in CO 2 permeability while maintaining selectivity. The membrane with 20 wt% ZIF-67-Hmim-PDMS-PEO demonstrated CO 2 /N 2 selectivity significantly surpassed that of the membrane prepared without pre-assembly. The membrane containing 30 wt% nanofluid exhibited a 235% enhancement (343.0 Barrer) in CO 2 permeability compared to pristine Pebax1657 membranes, with the selectivity of 51.2, reaching the 2008 upper bound for CO 2 /N 2 separation. These findings highlight the effectiveness of our approach in addressing key challenges in MMMs development for advanced gas separation applications.

Triboelectric nanogenerators (TENGs) hold significant potential for a wide range of applications such as harvesting small mechanical energy and enabling self-powered sensing technologies. However, their broader implementation is hindered by limited output performance and a short operational lifespan. This work tackles these challenges by developing a composite film with high charge density and enhanced wear resistance, consisting of molybdenum disulfide (MoS2) nanosheets and polydimethylsiloxane (PDMS). The 3 wt % MoS2/PDMS composite film exhibited an 8.8% reduction in friction coefficient compared to pure PDMS. In tribological testing, the composite film showed a significant increase in the number of linear cycles by 146.6% compared to pure PDMS. Under a contact pressure of 8.2 N and an operating frequency of 1.96 Hz, the two-electrode contact-separation mode TENG demonstrated remarkable peak performance metrics: an open-circuit voltage (Voc) of 410 V, a short-circuit current (Isc) of 42 μA, and a short-circuit transferred charge (Qsc) of 76 nC, representing improvements of 2.05, 2.1, and 2.17 times, respectively, compared to a pure PDMS-based TENG. When integrated with a transformer–rectification circuit, the TENG achieved a peak power output of 2.8 mW, sufficient to continuously power capacitors and light up 66 white LEDs. Notably, the TENG maintained stable output performance even after enduring 10,000 operational cycles. An arched TENG design was also created to detect the motion state of the human body. This research offers critical insights and advancements in the design of innovative triboelectric materials for TENG applications, paving the way for enhanced output performance and durability in self-powered systems.

This study investigates the synthesis, characterization and adsorption efficiency of PDMS@Li/ZnAl-LDH as a potential adsorbent for lithium recovery from Salt Lake brine with a high Mg/Li ratio. Synthesized via co-precipitation, the adsorbent exhibited excellent stability across a wide range of pH and temperature, along with a well-defined layered crystalline structure. The maximum adsorption capacity of Li + is 14.1 mg/g in lithium brine and 9.4 mg/g in the Qarhan Salt Lake's brine with impressive selectivity, as indicated by separation factors of 215, 838 and 175 for Li + /K + , Li + /Na + and Li + /Mg 2+ , respectively. Microspheres formed by Li/ZnAl-LDH in ultra-pure water exhibited tunable pore size and porosity as compared to Li/Al-LDH, which enhanced the Li + adsorption. Cyclic adsorption and zinc dissolution tests confirmed the adsorbent's excellent reusability with no significant structural degradation. Furthermore, using NaAlO 2 as a precursor reduces cost, making Li/ZnAl-LDH a viable option for large-scale lithium recovery. This work presents a sustainable, cost-effective strategy for lithium recovery with potential industrial applications.

Circularly polarized luminescence (CPL) has emerged as a critical technology for anticounterfeiting and optical display applications due to its unique chiroptical properties. We report a multicolor CPL-emitting elastomeric film (P37/PSK@SiO2-PDMS) that synergistically combines chiral helical polyacetylene (P37) and a surface-engineered perovskite (PSK@SiO2) through hydrogen-bond-directed assembly. Confinement within the PDMS matrix drives P37 to self-assemble into a chiral supramolecular structure through hydrogen bonding, inducing a chiroptical inversion. Simultaneously, surface modification of PSK@SiO2 enhances its compatibility with PDMS while enabling efficient chirality and energy transfer from P37 via interfacial hydrogen bonds. The resulting material exhibits exceptional CPL performance, achieving a maximum dissymmetry factor of 4.3 × 10–2 and a high photoluminescence quantum yield up to 67%. The PDMS matrix not only stabilizes the PSK components but also enables reversible, strain-tunable CPL modulation through its elastomeric properties. This work establishes a hydrogen-bonding paradigm for designing high-performance chiral PSK materials, while demonstrating their potential for dynamic photonic applications.

Tactile sensors are of great significance for robotic perception improvement to realize stable object manipulation and accurate object identification. To date, developing a broad-range tactile sensor array with high sensitivity economically remains a critical challenge. In this study, a flexible capacitive tactile sensor array, consisting of a carbon nanotube (CNT)/polydimethylsiloxane (PDMS) film, parylene films, and two polyimide (PI) films patterned with electrodes, is facilely prepared. The CNT/PDMS film, acting as a giant dielectric permittivity material, is utilized to improve the sensitivity, while the parylene film serves as the scaffold architecture to extend the working range of the tactile sensor array. Also, it is promising to realize mass production for this sensor array due to the scalable fabrication procedure. The as-prepared sensor exhibits excellent sensing performance with a high sensitivity of 1.61% kPa−1 (<1 MPa), an ultra-broad pressure working range of 0.9 kPa–2.55 MPa, an outstanding durability, a stability up to 5000 cycles, and a fast response time. By integrating our tactile sensor array with a robotic gripper, we show that robots can successfully differentiate object shapes and manipulate light and heavy objects with a closed-loop pressure feedback, demonstrating its great potential in robotic perception and wearable applications.

Electromagnetic interference (EMI) shielding materials with absorption-dominated EMI shielding mechanism can effectively annihilate electromagnetic waves (EMW) and avoid their repeated EMW pollution. However, it is difficult to achieve this goal for conductive polymer-based composites (CPC), because the interface impedance mismatch between air and CPC leads to massive reflection of EMW at the interface. Pores are beneficial to EMW penetrating into the interior of CPC and causing their multiple reflection, scattering and absorption in pores, thus endowing CPC with absorption-dominated EMI shielding characteristic. Herein, highly conductive silvered aramid microfibers (CAMF) were first synthesized via dopamine-assisted electroless deposition of silver coating on aramid microfibers (AMF), and then the conductive porous PDMS composite foams (PDMSF) with absorption-dominated EMI shielding characteristic were prepared and optimized via salt template method. As a result, PDMSF with 1.7 vol% silver content, the conductivity of PDMSF can reach 10 -1 S/m, the EMI shielding efficiency (EMI SE) can reach 36.7 dB in X-band, and the average absorption ratio in EMI SE is 87%, while the density of PDMSF is only 0.28 g/cm 3 . The combination of lightweight, high EMI SE and absorption-dominated EMI shielding characteristic makes the porous PDMSF the latent EMI shielding materials in special constructions (e.g. military, confidential and nuclear facilities, etc.), aerospace, military equipments and transportation, etc.

Resistive-type strain sensors have been widely studied because of their high precision and convenient measurement. But the high sensitivity and large strain range of this kind of sensor conflict with each other. It is difficult to prepare a sensor with high sensitivity and a large tensile range at the same time. Here, we propose a method to use AgNWs/Ag microparticles (AgMPs) and PDMS to simultaneously manufacture two strain sensors with different principles, a crack-based sensor and a composite-based sensor. On the one hand, the crack-based sensor has a low detection limit of 0.5% strain and high sensitivity of GF ≈ 90 at the strain of 0 ∼ 50%. It is suitable for the detection of small strains and can detect throat vibration when speaking. On the other hand, the composite-based sensor has a large strain range of 0 ∼ 240% and excellent stability. After 1000 cycles of stretching-releasing at 50% strain, the resistance change rate remains unchanged. It is suitable for the detection of large strains. Moreover, the sensitivity and working range of the composite-based sensor can be adjusted by changing the ratio and total amount of AgNWs/AgMPs composites. It can accurately monitor the different bending angles of the elbow joint and a people's walking status and pace. The strain sensor prepared by this method has great practical value in wearable devices and electronic skin.

Superhydrophobic cotton fabric was prepared by coating fluorine-free cationic polyhedral oligomeric siloxane/polydimethylsiloxane-modified polyacrylate emulsion using the pad-bath method. Due to the successful introduction of heptaoctylmethacryloxypropyl polyhedral oligomeric siloxane and monovinyl polydimethylsiloxane, the film with a rough structure and low surface energy was formed on the cotton fabric surface, exhibiting excellent superhydrophobicity with a water contact angle of 161°. Additionally, the finished cotton fabric showed exceptional self-cleaning and anti-foiling abilities. The finished cotton fabric had a separation efficiency of over 97% for oil–water mixtures and maintained a high separation efficiency of over 96% after 20 cycles of separating the n-hexane/water mixture. In addition, the separation of different water-in-oil emulsions was achieved by overlapping three layers of finished cotton fabric. This suggests that the as-prepared superhydrophobic cotton fabric will be a promising material in application for treating oil–water mixtures and water-in-oil emulsions due to the low-cost, simple fabrication method and the superior separation capabilities.

Flexible and transparent surface-enhanced Raman scattering (SERS) substrates have attracted much attention as a fast, sensitive and in situ detection platform for practical applications. However, the large-area fabrication of flexible and transparent SERS substrates with high performance is still challenging. Here, a flexible and transparent SERS substrate based on large-area thin PDMS film decorated with Ag microlabyrinth/nanoparticles hierarchical structures (denoted as ALNHS@PDMS) is fabricated by using the floating-on-water method and magnetron sputtering technology. By optimizing the sputtering time, the ALNHS with multiple hot spots are uniformly distributed on the PDMS surface. Based on characterizing the rhodamine 6G (R6G) with a portable Raman spectrometer, the optimal ALNHS@PDMS film exhibits a high enhancement factor (5.2 × 10 6 ), excellent uniformity and reproducibility, as well as superior mechanical stability. In addition, thanks to the good sticky feature and bi-directional activation property of the thin ALNHS@PDMS film, the prepared flexible and transparent SERS substrate can achieve in situ detection of malachite green residues (10 -6 M) on apple and tomato skins. This large-area, thin, mechanically robust, flexible and transparent ALNHS@PDMS film, integrated with a portable Raman spectrometer, shows great potential for point-of-care testing (POCT) in practical applications.
