Herein, the efficient selective bimetallic atomic electrode interface was cultivated via high-throughput screening, achieving self-adaptive parallel electrochemical reduction of Cu(II) and As(III). Combined in situ X-ray absorption fine structure (XAFS) spectroscopy and coordination field theory verified the Ni–Cu specific energy level matching promoted by permitted d–d transition and also reproduced the microscopic dynamic reduction process. Additionally, it was discovered that the Fe–As specific bonding and energy barrier of the smallest potential-determining step (1.40 eV) were derived from the linear shift of the main s and p peaks of the key arsenic intermediates to the high-energy orbital. This work offers insights into transient reaction dynamics by in situ methods and theoretical simulations, which broadens the design of multisite atomic catalysts.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"16 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143258444","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}

In this study, a composited microneedle that incorporated drug-loaded conjugated polymer nanoparticles and basic fibroblast growth factor was prepared to eliminate biofilms and promote vascular regeneration. This microneedle released minocycline under near-infrared (NIR) light, effectively penetrating bacterial biofilms. The photothermal properties of the conjugated polymers, combined with the antibacterial action of minocycline, contribute to the eradication of biofilms and the elimination of drug-resistant bacteria. Moreover, it regulated the wound microenvironment by reducing the level of oxidative stress, as well as the production of inflammatory factors at the wound site. Meanwhile, it effectively boosted cell migration and promoted angiogenesis to accelerate diabetic wound healing. This composited microneedle for biofilm elimination represents a promising approach for promoting diabetic wound healing.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"138 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143192657","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, achieving high-resolution near-field imaging with polarization and temporal sensitivity remains a significant challenge. In this work, we present a novel nonlinear optical microscopy technique based on degenerate four-wave mixing to enable spectrum- and polarization-resolved near-field imaging of plasmonic nanoantennas. By using a mid-infrared pump and near-infrared probe, we capture detailed spatial distributions of plasmon-enhanced near-field intensity and polarization characteristics, revealing distinct polarization patterns and frequency-dependent enhancements. Our method enables the observation of resonance-induced spectral shifts and subwavelength spatial resolution, offering valuable insights into plasmonic field behaviors, particularly in the mid-infrared range. This approach provides a powerful tool for exploring and understanding the complexities of plasmonic nanostructures, with significant potential for advancing nano-optics applications.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"23 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143258545","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 adopted copper as the principal component of nanoparticles (NPs), given its features of coordination with different benezenecarboxylate ligands to form metal–organic frameworks and complexes with distinct morphologies. As a result, four types of shape-tunable copper-coordinated NPs (CuCNPs) are developed: cuboctahedron, needle, octahedron, and plate NPs. Biocompatibility of CuCNPs varies across different cell lines (RAW264.7, THP-1, HEK 293 and HeLa) in a shape-dependent manner, with needle-shaped CuCNPs showing pronounced cytotoxicity (IC50:104.3 μg mL–1 at 24 h). Among different shapes, a notable increase of 8.47% in the CD206+ subpopulations is observed in needle-shaped CuCNPs, followed by 77% enhancement at 48 h. Overall, this study underscores the shape-dependent immune-regulatory effects of CuCNPs and sheds light on the rational design of nanoscale metal complexes for potential immunotherapy.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"21 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143258450","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, their applications are often restricted by their intrinsic fragility and decreased processability. Herein, a hierarchical fibrous MOF/ionic liquid (IL) membrane was constructed by assembling well-ordered ZIF-8 nanounits with an encapsulated IL along the polyimide (PI) fibers. This design promotes the formation of an efficient three-dimensional gas transfer network and generates an abundance of nanopores decorated with CO2-philic units, thereby enhancing the separation of CO2 from N2. The hierarchical fibrous PI/ZIF-8/IL membranes exhibit remarkable structural features, including a large specific surface area of 79.89 m2 g–1, a high porosity of 93.28%, and excellent mechanical stability. Moreover, the PI/ZIF-8/IL membranes demonstrate an enhanced CO2 adsorption capacity of 3.32 mmol/g at 298 K and 1 bar, an excellent CO2/N2 selectivity of 28, and a stable recyclable regeneration capability. The integrated hierarchical pore structure proposed in this study provides a practical direction for the rational design of MOF/IL membranes for targeted gas separation applications.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"11 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143258727","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}
