Current machine vision sensors, including frame-based and event-based types, often fall short due to their limited temporal dynamics compared with the human retina, hindering their overall performance and adaptability. In this work, we present an event-driven retinomorphic photodiode (RPD) that mimics the retina’s layered structure and signal pathway. The RPD achieves this by vertically integrating an organic donor–acceptor heterojunction, an ion reservoir with a porous web-like morphology, and a Schottky junction into a single diode through controlled layer-by-layer fabrication and precise nanostructure modulation. Each component replicates a key retinal process, and their spontaneous interaction results in environment-adaptive dynamics. This design yields a dynamic range exceeding 200 dB, substantially reduces noise and data redundancy, and allows for high-density integration. We demonstrate that these improvements enable high-quality machine vision, even under extreme lighting conditions. Our work demonstrates a bottom-up approach to retinomorphic sensors, propelling the development of robust and responsive machine vision systems adaptable to complex and dynamic lighting environments.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"163 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684940","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}

Spatially indirect interlayer excitons (IXs) exhibit broad tunability of their emission energy via the quantum-confined Stark effect. However, the electrical tunability of IXs has not been exploited in cavity-coupled systems until now. Here we modulate the detuning between the cavity resonance and the IX emission in a monolithic Fabry–Perot cavity using an applied vertical electric field. We reveal a simultaneous enhancement of both the emission intensity and lifetime of weakly coupled IXs when in resonance with the optical cavity owing to strong Purcell inhibition and cavity transparency effects. We further investigate the tunable momentum dispersion of coupled IXs through back-focal-plane imaging and explain our results by the cavity coupling of IX transition dipoles as supported by theoretical modelling. Our work demonstrates an integration effort enabling the versatile tuning of highly interacting IXs within monolithic cavities, revealing the attractiveness of electrically tunable IX cavity coupling for both fundamental studies towards exciton condensate manipulation and future integration of excitonic devices.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"29 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144645478","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}

With an industrially friendly manufacturing method, we produce crumpled GO membranes with gas diffusion pathways controlled by a multidomain structure. These membranes achieve H2 permeability of approximately 2.1 × 104 barrer, significantly surpassing the permeability of flat lamellar GO membranes, which is below 100 barrer. Its H2/CO2 selectivity of 91 outperforms current membrane technologies. In addition, the crumpled membranes demonstrate stability under harsh conditions (−20 °C, 96% relative humidity), a critical requirement for practical applications. This work addresses the long-standing permeability–selectivity trade-off and establishes a robust, scalable platform for integrating two-dimensional materials into membrane technology for real-world applications.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"14 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622424","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, lack of highly effective sonosensitizers and control over chemodynamic therapy limit their application. Here we synthesize silver-doped zinc selenide quantum dots with atomically dispersed superficial Fe and show that they act as efficient sonosensitizers, catalysers and immunoreagents. Surface modification with an in situ self-assembly peptide drives accumulation in tumours. Superficial FeIII remains stable and converts to FeII only under ultrasonic processing, reverting to FeIII upon ultrasound cessation. Under ultrasound stimulation, superficial Fe undergoes valence change with concomitant amelioration of the hypoxic tumour microenvironment and production of sonodynamic therapy-beneficial hydroxyl radicals. Furthermore, silver doping suppressed nonradiative recombination of excitons, leading to improved production of singlet oxygen. Meanwhile, selenium promotes robust systemic immune responses for the inhibition of tumour metastases. This nano-platform allows control of valence switching of atomically dispersed catalysts, representing an effective tool for chemodynamic/sonodynamic/immunotherapy.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"1 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594140","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}

Here, inspired by the collective oscillation of spatially localized modes and Fourier duality between real and momentum spaces, we demonstrate a chiral emission of collective guided modes by leveraging the omnidirectional hybridization of individual guided resonances within a photonic crystal slab. Specifically, we encircle a uniform photonic crystal with isotropic boundaries and hybridize discrete bulk guided resonances into a series of collective modes owing to the scatterings of the boundaries. This results in a chiral spiral vortex emission in real space. By using asymmetric pumping to lift the chiral symmetry, we then achieve stable single-mode lasing oscillation of the spiral collective mode and confirm the nature of vortex emission through polarization-resolved imaging and self-interference patterns, thus demonstrating a vivid example of collective oscillations in the momentum space.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"27 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144521098","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 RNA detection methods are hindered by data complexity and error-prone protocols, restricting their widespread use. Here we present a solid-state nanopore-based approach, RNA single-nucleotide characterization and analysis nanolatch (RNA-SCAN) system, which simplifies the detection of nucleotide mutations and modifications in RNA with high resolution. Using phage RNA as a template, we tested multiple sequences and chemical modifications on nanolatches, allowing the detection of mismatches caused by nucleotide mutations through significant changes in positive event ratios using single-molecule nanopore measurements. This approach is also sensitive to modifications that either strengthen or weaken the interaction between the target RNA sequence and the nanolatch. As a proof-of-concept, we demonstrate successful discrimination of Escherichia coli and Salmonella spp. from total RNA based on nucleotide variations in their 16S rRNA, as well as quantification of different Salmonella spp. and detection of m5C1407 modification on E. coli 16S rRNA. The RNA-SCAN approach demonstrates the feasibility of combining RNA/DNA hybrid nanotechnology with nanopore sensing and diagnosing RNA-related health conditions.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"46 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144500490","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}
