However, these oxides are highly susceptible to surface damage during conventional top-electrode deposition processes, which leads to interfacial disorder and degraded switching reliability. Here, we demonstrate a highly reliable and flexible NbO_x–NbSe₂ memristor utilizing a damage-free van der Waals (vdW) metal transfer technique. By gently laminating a prefabricated gold (Au) electrode onto the NbO_x–NbSe₂, a pristine and chemically undisturbed metal/oxide interface is achieved. While metallization-induced barrier damage causes a large OFF-state direct tunneling (DT) current in the evaporated-metal memristor (Ev-MEM), preserving the pristine oxide interface in the transferred-metal memristor (T-MEM) effectively suppresses this OFF-state DT current. Consequently, the T-MEM exhibits an ON/OFF ratio of 10⁵—a 1,000 times improvement over the Ev-MEM (10²)—along with a stable retention time of &gt; 10⁴ s and an endurance exceeding 10³ cycles. Furthermore, the T-MEM exhibits exceptional synaptic linearity (<i>β</i> = 0.6) and a full dynamic range (0–1), in contrast to the Ev-MEM, which suffers from poor linearity (<i>β</i> = 3.1) and a limited dynamic range (0.2–1). As a result, a hardware-aware convolutional neural network (CNN) simulation shows a near-ideal MNIST image recognition accuracy of 98.1% for the T-MEM based system, significantly outperforming the Ev-MEM counterpart (75.8%). In addition, capitalizing on the inherent flexibility of the 2D NbSe₂ and the vdW interface, devices fabricated on a polymer substrate demonstrate remarkable mechanical robustness, maintaining stable switching characteristics over 200 bending cycles at a 30° angle. Our findings establish that damage-free vdW metal integration is a crucial prerequisite for developing reliable, highly accurate, and flexible neuromorphic hardware.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"13 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13447627/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148676891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study first analyzes clinical data of fractional flow reserve, optical coherence tomography (OCT), and computed tomography from 180 patients over a 9 years period, with an average follow-up of 2 years. When the plaque progression and healthy control groups were compared in a 1:1 match (n = 10 each), analysis of single artery images failed to detect plaque progression. Therefore, 100–200 image frames were used to reconstruct patient-specific coronary anatomy using computational fluid dynamics, enabling prognostic assessment of plaque progression. The results suggest that steep plaque slopes promote plaque progression by increasing shear stress and hemodynamic disturbance accompanied by greater macrophage recruitment than gentle slopes, which was validated by a microfluidic model. Moreover, increased activation and fusogenic potential of macrophages in steep plagues justified the development of fusogenic macrophage (FM)-vesicles to detect plaque progression. The fusion potential enables FM-vesicles to self-target fusogenic macrophages more efficiently than in vitro compared to macrophages, showing superiority over liposomes and macrophage-vesicles. The membrane fusion mechanism facilitates lysosomal escape, allowing prolonged cytosolic retention without degradation. Rabbit carotid ligation was used to produce steep and gentle plaques by controlling the incision direction. When gold nanoparticles were loaded into FM-vesicles and injected into these arteries ex vivo, OCT accurately imaged the plaque slope and detected changes in signal intensity. This study presents the translational potential of FM-vesicles for clinical application by reducing diagnostic outliers in the detection of plaque progression.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"13 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2026-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s40580-026-00567-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148614706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sublethal H₂O₂ exposure impaired stiffness-dependent cytoskeletal remodeling, focal adhesion maturation, and traction-force generation during cell spreading. Quantitative force mapping further revealed disrupted contraction-unit (CU)-associated nanoscale force coordination at the cell periphery, characterized by increased alignment of neighboring traction-force vectors and reduced opposing contractions.

We first summarize enabling technologies, including advanced in vitro and ex vivo systems, organoids, microphysiological systems, high-dimensional single-cell multi-omics and label-free hyperspectral imaging, AutoML, generative AI, physiologically based kinetic modeling, and in vitro-to-in vivo extrapolation. We then analyze the regulatory landscape, emphasizing OECD harmonization efforts, the Mutual Acceptance of Data system, and regional developments across Europe, Africa, the Americas, and Asia–Pacific. A central theme is that regulatory acceptance of NAMs for nanomaterials requires not only biological relevance, reproducibility, and context-of-use definition, but also robust physicochemical characterization, exposure control, dosimetry, and data interoperability. Industrial implementation in pharmaceuticals, cosmetics, agrochemicals, antimicrobials, and environmental protection is discussed as a measure of regulatory readiness and scalability. Finally, we outline future directions involving Smart NAMs, digital twins, and Safe and Sustainable by Design (SSbD) frameworks.
