Antibacterial properties are as critical as filtration efficiency in water treatment membranes, as they determine longevity and biofouling resistance. This study reports the fabrication of flexible antibacterial films featuring an in situ fluorine-doped laser-induced graphene (F-LIG) surface, generated via direct CO₂ laser writing on fluorinated polyimide (F-PI) substrates. By adjusting laser parameters, the surface wettability of F-LIG is tuned from hydrophilic to highly hydrophobic (contact angle: 131.5°). The hydrophobic F-LIG exhibited synergistic antibacterial activity through (1) chemical inhibition, where fluorination-induced low surface energy suppressed bacterial adhesion, and (2) physical disruption, where nanoscale roughness mechanically damaged bacterial cells. Antibacterial tests against Escherichia coli and Staphylococcus aureus demonstrated up to 80.7% bacterial removal, surpassing the hydrophilic variant. Furthermore, a bacterial-responsive Janus membrane is fabricated by combining an F-LIG top layer with a porous fluorinated polyimide (F-PPI) substrate, prepared via non-solvent-induced phase separation (NIPS). Permeability and dye removal experiments using pigment blue 15:3 and methylene blue revealed that the porous F-LIG membranes achieved removal efficiencies of up to 96.3% and 83.9%, respectively, despite slightly lower permeability than commercial PVDF filter paper. These results highlight the promise of F-LIG-based membranes that integrate antibacterial and filtration functions within a single platform.

Self-assembled monolayers (SAMs) have long become an important element of modern nanotechnology. Apart from their primary use in tailoring the chemical and physical properties of surfaces and interfaces, they can be modified by physical tools, with electron irradiation being probably the most useful and versatile one. Here, the development and current state of this field is reviewed, addressing both fundamental aspects of this modification and the related implications and applications. Various types of SAMs, differing in their reaction to electron irradiation, are considered, and the impact of relevant factors affecting these reactions, such as the SAM quality, primary electron energy, and temperature, is analyzed. Based on this knowledge, the current applications of SAM engineering by electrons are introduced and discussed. These applications include tuning the SAM properties, preparation of binary SAMs, conventional and chemical lithography, fabrication of carbon nanomembranes (CNMs), enabling metal deposition onto SAMs, and design and fabrication of biointerfaces. Some of these applications, like chemical lithography and functional CNMs, are unique and can hardly be realized with any other technology. They hold significant potential for the future and will presumably soon make a transition from prototype laboratory experiments to real-life industrial applications.

The development of functional surfaces with engineered wetting properties and droplet behaviors has attracted significant interest for applications in biomedical engineering, electronics, and microfluidics. However, achieving precise, localized engineering of surface wettability remains a significant challenge in both fabrication and modeling. In this study, a novel acoustic assembly photopolymerization (AAP) method is introduced for fabricating surfaces with predictable anisotropic and gradient wettability. The relationship between the APP process parameters and the fabricated film properties is established to enable the accurate fabrication of surfaces capable of self-guided liquid manipulation. Theoretical models of flow dynamics in open capillary grooves are developed to predict the liquid flow behavior within microchannels. By tailoring the process-property relationship, the droplet motion and droplet transport time can be precisely controlled within a 5–30 s window. Experimental validation confirms that AAP-fabricated surfaces enable predictable droplet transport with less than 5% mean error from theoretical predictions, demonstrating tunable hydrodynamic performance. This work advances the understanding of microscale fluid dynamics on anisotropic surfaces and presents a scalable approach for manufacturing next-generation microfluidic devices. Notably, the demonstrated capability for designed, gradient-driven liquid transport without external energy input opens new avenues for on-chip chemical synthesis, point-of-care diagnostics, and biosensing applications.

This study presents the development of a novel material capable of efficiently enriching and recovering pathogenic bacteria from food matrices without requiring surface modification of biological components or complex chemical conjugation. A nanocellulose-based chitosan aerogel (CNF-CS) is synthesized via cross-linking of nanocellulose, extracted from pulp, with chitosan. The CNF-CS aerogel enables selective adsorption of negatively charged bacterial cells through electrostatic interactions. When integrated with a custom-designed micro-injection extrusion enrichment device, the system achieves rapid and efficient enrichment and recovery of foodborne pathogens. The CNF-CS aerogel-based system demonstrated a high enrichment efficiency of (96.30 ± 1.01)% and an elution rate of (89.16 ± 3.08)% for target pathogens. The entire enrichment and elution process is completed within (6.16 ± 0.05) min using 800 mL liquid samples or complex real-food matrices, including milk, watermelon, and oyster. Furthermore, the constituent materials of the CNF-CS aerogel are environmentally benign, biodegradable, and derived from sustainable sources. The aerogel can be tailored in terms of size, shape, and thickness to meet specific application requirements, highlighting its adaptability and strong potential for practical implementation and widespread adoption.

Superhydrophobic surfaces have important application prospects and value in industry and daily life. However, the practical application of superhydrophobic surfaces is severely hindered by their poor durability. Endowing artificial superhydrophobic surfaces with self-healing ability has become a key development direction for prolonging their service life. According to the fabrication principles of superhydrophobic surfaces, the repair of superhydrophobicity can be achieved through the migration of low-surface-energy substances or the reconstruction of hierarchical micro/nanostructures. While the repair of both chemical compositions and micro/nanostructures is equally important for regaining superhydrophobicity, restoring the structures is significantly more difficult. Moreover, current research focuses more on the restoration of surface chemical compositions rather than micro/nanostructures. This review systematically summarizes the recent development in structurally self-healing superhydrophobic surfaces, mainly including the biomimetic dynamic repair mechanisms and stimuli-responsive repair approaches for superhydrophobic micro/nanostructures. The recovery mechanisms of surface micro/nanostructures are mainly based on particle reconstruction, polymer swelling effect, elastic recovery behavior, shape-memory effect, phase-change property, and reversible dynamic bonds. Various stimuli-responsive repair approaches (e.g., heat-, light-, electricity-, or solvent-induced, and autonomous repair) for superhydrophobic micro/nanostructures are introduced sequentially. Finally, the challenges and future prospects of structurally self-healing superhydrophobic surfaces are discussed.

Electronic textiles represent a transformation in wearable biomedicine by integrating sensing, actuation, data communication, and therapeutic delivery into lightweight and deformable fabric. Recent advancements in conductive polymers, carbon nanomaterials, and natural fiber composites have significantly enhanced the strain sensitivity, mechanical durability, and long-term biocompatibility of e-textiles. This review synthesizes the current state of the art in e-textile materials and addresses three core research questions: fabrication technologies and materials, sensing mechanisms, and energy harvesting and storage systems. Hybrid materials incorporating PEDOT: PSS-coated polyurethane, graphene-silver composites with sheet resistance, silk-polypyrrole hydrogels, and ZnO-patterned piezoelectric structures demonstrate tunable conductivity, exceptional stretchability, and multi-responsive properties. Multimodal sensing technologies, such as capacitive, resistive, bioimpedance, piezoelectric, tribioelectric, and optical, enable real-time monitoring of cardiovascular, respiratory, neuromuscular, and biochemical markers. Self-healing ionogel fibers with a dynamic covalent network and a degradable thermoset provide durability and sustainability. Further, integrating an energy system comprising supercapacitors, triboelectric nanogenerators, and piezoelectric fibers eliminates the need for batteries. Closed-loop therapeutic systems autonomously modulate treatment based on biosensor feedback, including glucose-responsive drug delivery and electroactive wound healing. Challenges remain in long-term reliability, standardization, and large-scale manufacturability. This review identifies future directions encompassing artificial intelligence integration, biodegradable materials, and multi-modal sensor fusion to advance clinical translation of e-textile platforms for personalized, preventive, and decentralized healthcare.

To the increasing demand for textiles that are both health-conscious and environmentally friendly, this study investigates the production of antimicrobial textiles using a binder-free, plasma-assisted dip-coating technique. Silver-doped Zinc Oxide (Ag–ZnO) nanocomposites are synthesized and applied to cotton-polyester (CVC) and cotton-black viscose (CBV) blend-knit fabrics. Silver doping reduced the ZnO crystallite size to 25.97 nm and modified its surface energy and growth characteristics. X-ray diffraction confirmed the hexagonal wurtzite phase of ZnO along with distinct silver peaks, verifying successful doping without structural distortion. FTIR analysis showed strong Zn─O and Ag─O bonding, while FESEM revealed uniform nanoparticle coverage (40–80 nm) across both fabric types. Antibacterial efficacy, tested via the Kirby-Bauer disk diffusion method, showed inhibition zones of up to 17 mm for E. coli and 15 mm for S. aureus. Notably, significant antibacterial activity remained after 10 home laundering cycles with detergent. CFU demonstrated a potent antibacterial response against E. coli. Therefore, better tensile characteristics and sufficient elongation are found in the bundle fiber strength test, indicating increased comfort and durability. The enhanced comfort behavior and effective moisture management are further highlighted by the micro-drop wicking test, which revealed superior moisture absorption and spreading ability.

Low-dimensional materials hold great promises for exploring emergent physical phenomena, nanoelectronics, and quantum technologies. Their synthesis often depends on catalytic metal films, from which the synthesized materials must be transferred to insulating substrates to enable device functionality and minimize interfacial interactions during quantum investigations. Conventional transfer methods, such as chemical etching or electrochemical delamination, degrade material quality, limit scalability, or prove incompatible with complex device architectures. Here, a scalable, etch-free transfer technique is presented, employing Field's metal (51% In, 32.5% Bi, and 16.5% Sn by weight) as a low-melting-point mechanical support to gently delaminate low-dimensional materials from metal films without causing damage. Anchoring the metal film during separation prevents tearing and preserves material integrity. As a proof of concept, atomically precise graphene nanoribbons (GNRs) are transferred from Au(111)/mica to dielectric substrates, including silicon dioxide (SiO₂) and single-crystalline lanthanum oxychloride (LaOCl). Comprehensive characterization confirms the preservation of structural and chemical integrity throughout the transfer process. Wafer-scale compatibility and device integration are demonstrated by fabricating GNR-based field-effect transistors (GNRFETs) that exhibit room-temperature switching with on/off current ratios exceeding 10³. This method provides a scalable and versatile platform for integrating low-dimensional materials into advanced low-dimensional materials-based technologies.
