Here we report a manually operated portable water disinfection system that can inactivate 99.9999% of Vibrio cholerae within 1 min and demonstrate broad-spectrum disinfection against bacteria, fungi, parasites and viruses. Amino-modified SiO<sub>2</sub> nanoparticles loaded with Au nanoparticles capture hydrated electrons and transfer them to the electret surface to generate localized nanoscale electric fields, which are further strengthened by hydrophobic fluorinated groups. This interfacial architecture not only promotes charge accumulation and transfer, but also leverages the intensified electric field to actively drive reactive oxygen species generation at the solid-liquid-air interface, thereby markedly enhancing the disinfection rate and efficacy compared with existing contact-electrification-based disinfection technologies. Owing to its ease of operation, our interfacial electric-field-enhanced disinfection system is readily deployable in disaster relief and resource-constrained regions.</p>","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":" ","pages":""},"PeriodicalIF":34.9,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145302031","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}

However, current techniques often rely on destructive endpoint assays that require cell lysis, losing spatial, temporal and dynamic context. Nanoscale sensors offer a transformative solution by enabling minimally invasive, continuous monitoring of intracellular activities. Here we propose a spatial classification of intracellular sensing technologies—near cell, on cell and in cell—and use this framework to evaluate the sensing modalities on the basis of their invasiveness, signal fidelity and resolution. We highlight emerging sensor platforms that are capable of detecting ions, metabolites, electrical signals and mechanical changes, as well as artificial intelligence-driven strategies for decoding complex cellular data streams. We further consider the integration of these nanosensors into three-dimensional, physiologically relevant models such as organoids to create ‘smart organoids’ that report on their internal state autonomously and in real time. Finally, we discuss the major challenges in achieving intelligent intracellular sensing, including issues of sensor miniaturization, biocompatibility, multiplexing and three-dimensional integration. Together, these advances set the stage for a new era of dynamic, high-resolution cell profiling that can accelerate drug discovery, disease modelling and personalized medicine. This Review provides insights into nanosensor technologies for monitoring cellular biomarkers, proposing a spatial framework to clarify their distinct advantages, challenges and performance for high-resolution, dynamic profiling of cellular analytes.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 10","pages":"1374-1387"},"PeriodicalIF":34.9,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145302099","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}

To address surface defects in the top perovskite junction, we introduce a piperazine-1,4-diium chloride treatment, which replaces less stable lithium fluoride. For interfacing the top and middle perovskite junctions, we optimize the size of gold nanoparticles deposited on atomic layer-deposited tin oxide for best ohmic contacting with minimal optical losses. Applying these strategies, our champion 1-cm2 triple-junction cell achieved a third party-verified reverse-scan power conversion efficiency of 27.06% with an open circuit voltage of 3.16 V. Scaling up to 16 cm2, the device produced a certified steady-state power conversion efficiency of 23.3%. Device longevity also improved by eliminating methylammonium and incorporating rubidium into the perovskite bulk alongside the piperazine-1,4-diium chloride surface layer. An encapsulated 1-cm2 cell retained 95% of its initial efficiency after 407 h at maximum power point and passed the IEC 61215 thermal cycling test.

Here, by combining density functional theory with Metropolis Monte Carlo methods, we discovered that sufficient stabilization in the RuO2 lattice could be achieved with less than 50 at.% of Ir, and that Ir in the first subsurface layer plays a critical role. By effectively dispersing Ir dopants within the RuO2 lattice, we demonstrated an Ir:Ru atomic ratio of only 1:6 that exhibited exceptional stability for over 1,500 h of continuous water electrolysis at 2 A cm-2. Our Ru6IrOx catalyst has the potential to reduce Ir loading by 80% compared with current commercial PEM water electrolysers, and its stability was further validated under industrial testing conditions in a 25-cm2 PEM electrolyser.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"28 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145241010","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}

Early in the regeneration process, pro-inflammatory macrophages contribute to immune imbalance, while in later stages, senescent stem cells reduce regenerative capacity. Here we demonstrate that nicotinamide adenine dinucleotide (NAD+) can reprogramme both types of dysfunctional cell. We developed a spatiotemporal-adaptive nanotherapeutic system for the delivery of NAD+ into selected cells during different phases of tissue repair. By replenishing intracellular NAD+ pools, this system reshapes the multicellular regeneration niche, by metabolically rewiring pro-inflammatory macrophages towards a pro-repair phenotype during the early phase, and enhancing the differentiation capacity of senescent stem cells at later stages. This strategy effectively restored impaired bone regeneration in osteoporotic mice and accelerated skin wound healing.

Determining the spatial distributions of coupled electronic and vibrational states is essential to understanding interacting polarons at a microscopic level but remains a challenge. Here we report the crystallization of electron polarons into quasi-one-dimensional polaron superlattices in highly n-doped single ethynylene-bonded polypentacenes. We employ integrated scanning tunnelling microscopy, atomic force microscopy and tip-enhanced Raman spectroscopy combined with first-principles density functional theory to correlate electronic, vibrational and structural information. The observed polaron superlattices exhibit different periodicities that depend on the doping levels. Their real-space polaron wavefunctions are determined by the intertwined electronic and vibrational periodic modulations associated with the periodic lattice distortions as resolved by atomic force microscopy. We can then identify the multiband charge-density-wave attributes of interacting polarons in these superlattices. Our findings provide microscopic insights in interacting polarons, which is important for the understanding of polaronic charge transport mechanisms in organic semiconductors.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"37 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145134307","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}
