Electrospun nanofibers are particularly well-suited for E-skin applications due to their exceptional mechanical properties, tunable breathability, and lightweight nature. Nanofiber-based composite materials consist of three-dimensional structures that integrate one-dimensional polymer nanofibers with other functional materials, enabling efficient signal conversion and positioning them as an ideal platform for next-generation intelligent electronics. Here, this review begins with an overview of electrospinning technology, including far-field electrospinning, near-field electrospinning, and melt electrospinning. It also discusses the diverse morphologies of electrospun nanofibers, such as core-shell, porous, hollow, bead, Janus, and ribbon structure, as well as strategies for incorporating functional materials to enhance nanofiber performance. Following this, the article provides a detailed introduction to electrospun nanofiber-based composite materials (i.e., nanofiber/hydrogel, nanofiber/aerogel, nanofiber/metal), emphasizing their recent advancements in monitoring physical, physiological, body fluid, and multi-signal in human signal detection. Meanwhile, the review explores the development of multimodal sensors capable of responding to diverse stimuli, focusing on innovative strategies for decoupling multiple signals and their state-of-the-art advancements.

However, these immobilization strategies inevitably compromise the interfacial mass diffusion and cause activity decline relative to the suspended catalyst. Here, we propose a binder-free surface immobilization strategy for fabrication of high-activity photocatalytic membrane. Through a simple dimethylformamide (DMF) treatment, the nanofibers of polyvinylidene fluoride membrane were softened and stretched, creating enlarged micropores to efficiently capture the photocatalyst. Subsequently, the nanofibers underwent shrinking during DMF evaporation, thus firmly strapping the photocatalyst microparticles on the membrane surface. This surface self-bounded photocatalytic membrane, with firmly bounded yet highly exposed photocatalyst, exhibited 4.2-fold higher efficiency in hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) photosynthesis than the matrix-embedded control, due to improved O<sub>2</sub> accessibility and H<sub>2</sub>O<sub>2</sub> diffusion. It even outperformed the suspension photocatalytic system attributed to alleviated H<sub>2</sub>O<sub>2</sub> decomposition at the hydrophobic surface. When adopted for UV-based water treatment, the photocatalytic system exhibited tenfold faster micropollutants photodegradation than the catalyst-free control and demonstrated superior robustness for treating contaminated tap water, lake water and secondary wastewater effluent. This immobilization strategy can also be extended to the fabrication of other photocatalytic membranes with diverse catalyst types and membrane substrate. Overall, our work opens a facile avenue for fabrication of high-performance photocatalytic membranes, which may benefit advanced oxidation water purification application and beyond.</p>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"17 1","pages":"301"},"PeriodicalIF":26.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12176716/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144324120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report the discovery of two-dimensional (2D) TiO2, characterized by a micro-sized lateral dimension (~1.6 μm) and atomic-scale thickness, which fundamentally resolves these long-standing issues. The 2D structure enables exceptional light management, achieving 80% visible light transparency-rendering it nearly invisible on the skin-while maintaining UV-blocking performance comparable to unmodified rutile TiO2 nanoparticles. Its larger lateral size results in a two-orders-of-magnitude reduction in skin penetration (0.96 w/w%), significantly enhancing biosafety. Moreover, the unique layered architecture inherently suppresses the generation of reactive oxygen species (ROS) under sunlight exposure, reducing the ROS generation rate by 50-fold compared to traditional TiO2 nanoparticles. Through precise metal element modulation, we further developed the first customizable sunscreen material capable of tuning UV protection ranges and automatically matching diverse skin tones. The 2D TiO2 offers a potentially transformative approach to modern sunscreen formulation, combining superior UV protection, enhanced safety and a natural appearance.","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"5 1","pages":"300"},"PeriodicalIF":26.6,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
