Here we demonstrate that twisted bilayer stacking can induce dipolar vortices in metallic SrRuO3 membranes, despite the presence of free charge. These vortices are correlated with moiré-periodic flexoelectricity induced by shear strain gradients, and their magnitude depends on both the twist angle and proximity to the interface. In addition, below the ferromagnetic Curie temperature of the films, ferromagnetic order coexists—and appears to compete—with the dipolar order, showing opposite twist-angle dependencies of the respective magnitudes of the two multiferroic order parameters. Density functional theory calculations provide insight into the microscopic origin of these observations. These findings extend the scope of topological polarization design beyond dielectric materials and into metals.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"10 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087802","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}

Conventional semiconductor photosensors lack intrinsic mechanisms for spike generation with tunable amplitude, requiring complex multitransistor architectures and limiting efficiency. Here we report an event-driven organic photosensor that integrates temporal-contrast detection and amplitude modulation within a single active layer by coupling ionic and electronic transport in an organic mixed ionic–electronic conductor. In a bulk heterojunction with a non-fullerene acceptor, fast electron extraction generates excitatory photocurrent spikes, whereas ion-compensated hole accumulation in the organic mixed ionic–electronic conductor donor provides voltage-tunable inhibitory control over spike amplitude—functionally analogous to attentional gain modulation in biological vision. This enables in-sensor amplitude–temporal coding, preserving motion-relevant contrast in bias-weighted optical events and reducing redundant read-out. These results establish ionic–electronic coupling in organic mixed ionic–electronic conductors as a materials strategy for adaptive, low-power neuromorphic vision hardware.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"23 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087823","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 we develop masked AAVs, whose transduction is blocked and restored only on pathological activation or by activation triggered by exogenous signals. The masking effect is accomplished by genetic encoding of non-canonical amino acid with tetrazine groups into AAV capsid proteins, allowing efficient reaction with trans-cyclooctene-modified truncated AAV receptor or polyethylene glycol to completely block viral infectivity in mice. With three different cleavable linkers, masking groups are selectively removable through liver-specific protease matriptase-2, near-infrared light or inflammation-associated reactive oxygen species, thus restoring the infectivity of AAVs and allowing localized transduction in mice. Systemic administration of protease-activated masked AAVs enables tissue-specific gene delivery to the liver, while administration of near-infrared-activated masked AAVs provides localized transduction in irradiated regions such as muscles and brain. Intravenous administration of reactive-oxygen-species-activated AAVs achieves targeted gene delivery to the myocardium in a cardiac ischaemia-reperfusion injury model, resulting in the localized expression of VEGF-A165 and myocardial repair.</p>","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149081534","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}
