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. Our work presents a spatiotemporal-adaptive nanomedicine platform that bridges cell metabolism, nanomedicine and regeneration therapy.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"124 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145203628","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}

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}

While extracellular vesicles hold substantial biomedical potential, conventional methodologies for isolating extracellular vesicles require elaborate preprocessing and, therefore, remain labour intensive and limited by throughput. To overcome these challenges, we present a facile fabrication route for generating a meso-macroporous hydrogel matrix with pores of ~400 nm for customizable extracellular vesicle isolation. By combining surface charge-selective capture of extracellular vesicles within the hydrogel matrix and their recovery by high ionic strength, we report direct extracellular vesicle isolation with a throughput range from microlitre to litre scales, without preprocessing, for various biofluids, including whole blood, plasma, ascites, saliva, urine, bovine milk and cell culture media. Furthermore, we demonstrate that the meso-macroporous hydrogel also serves as a solid-phase matrix for preserving extracellular vesicles for on-demand downstream analyses, making it applicable for therapeutics, cosmeceuticals and disease diagnostics.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"87 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145134574","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}

Solid-state nanopores provide an effective method to linearize and thread full-length proteins in a single file. However, slowing their rapid translocation remains a challenge for accurate, time-resolved ion-current-based fingerprinting. In this work, we present a click-chemistry-based strategy for covalently attaching short oligonucleotides to cysteine residues on denatured proteins across a broad range of molecular weights. The negatively charged oligonucleotides increase the capture rate by a factor of ten compared with native proteins and induce a distinct 'stick-slip' motion that slows protein passage through the nanopore by more than 20-fold. These oligonucleotide tags also produce characteristic, time-resolved ion current pulses that serve as unique protein-specific signatures. To uncover the physical mechanism responsible for the protein translocation dynamics, we model our system using all-atom molecular dynamics and finite element simulations. By leveraging a supervised machine learning classifier, we demonstrate that a small number of translocation events is sufficient to identify individual proteins, achieving near-perfect classification accuracy. To demonstrate the robustness of the method, we successfully distinguish between VEGF-A isoforms (VEGF-165 and VEGF-121), which are relevant to cancer diagnostics, within a mixed protein sample. Our nanopore-based fingerprinting technique eliminates the need for affinity reagents, such as protein-specific antibodies, or motor proteins, offering a rapid, direct and cost-effective approach for single-molecule protein identification and classification.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"95 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145134308","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}
