1. Nanoconfined Bi2Se3@Carbon-Tube Inbuilt Heterointerface for Highly Stable Flexible Multimodal Sensor.
1. 纳米限域Bi2Se3@碳管内置异质界面用于高稳定柔性多模态传感器PMID:日期:2026-09-30Flexible sensors normally require highly stable structural interfaces to sense various signals continuously and steadily under repeated deformation. Especially, for carbon-tube-derived flexible devices, however, functional components are typically deposited on the exterior of conductive networks, where they disrupt tube-tube contacts and leave active interfaces vulnerable to aggregation, delamination, and signal drift. Here, we report an internally nanoconfined Bi2Se3@carbon-tube hybrid with an inbuilt heterostructure architecture, in which Bi2Se3 is grown inside bamboo-like carbon tubes (BCTs). The BCT shell serves as both a continuous carrier pathway and a mechanically protective sheath, while the built-in Bi2Se3-carbon interface enables stable thermoelectric and photoinduced carrier transport. Compared with the externally decorated BCT@Bi2Se3, the product forms a more stable ink dispersion (over 130 days) and uniform spray-coated films, and the derived flexible sensor displays superior bending-piezoresistive (over 3000 cycles), thermoelectric (7-fold higher), and photoelectric (3.4-fold higher) multimodal response behaviors in a single device. Furthermore, mounted on a robotic finger, the sensor provides complementary descriptors of material, geometry, and optical appearance, showing an identified accuracy of 100% for six similar cups by fusing these signals to a one-dimensional convolutional neural network model. This internal encapsulation strategy converts fragile hybrid interfaces into protected, transport-efficient heterointerfaces for durable robotic perception.

2. Nonsurgical Platelet Membrane-Decorated Gold Yarnball Brain Antenna for In Situ Nitric Oxide Generation and Neuronal Regeneration.
2. 非手术治疗的血小板膜修饰金线球脑天线用于原位一氧化氮生成和神经元再生PMID:日期:2026-09-16Bioelectronic implants for brain stimulation are widely used to treat neurological disorders and promote neuronal repair; however, their clinical application is limited by invasive surgical implantation. To address this challenge, here, platelet membrane-decorated gold yarnballs double as a brain antenna and a miniaturized chemo-electrical reactor for neuron electric stimulus and gas-controlled release in traumatic brain injury (TBI). The platform consists of a nitric oxide (NO) donor-functionalized platelet membrane (PMNO) conjugated onto a gold yarnball nanoparticle (GNP). Upon exposure to an external high-frequency magnetic field (HFMF), the conductive GNP generates eddy currents that electrically stimulate neural regeneration while simultaneously triggering controlled NO release from PMNO. This dual-mode stimulation enhances neurogenesis, suppresses astrocyte activation, and promotes angiogenesis at the injury site, leading to significantly improved synaptic differentiation and neurite outgrowth of neural stem cells (NSCs). In vivo studies show that combined wireless electrical stimulation and NO signaling suppress inflammation, enhance vascularization, and promote neuronal regeneration in TBI. Behavioral analyses further reveal improved motor coordination and functional recovery in treated mice. The system offers a noninvasive alternative to implanted bioelectronic devices.

3. Photon-Driven Cluster Fluxionality: Breaking the Bulk Stoichiometry Ceiling in Subnanometric Molybdenum Oxides.
3. 光子驱动的团簇流变性：突破亚纳米氧化钼的体相化学计量上限PMID:日期:2026-09-08We investigate the low-temperature (40 K) oxidation behavior of size-selected molybdenum clusters supported on epitaxial graphene. By combining high-resolution X-ray photoelectron spectroscopy with first-principles density functional theory, we demonstrate that subnanometric clusters can break the stoichiometric ceiling of bulk transition-metal oxides. Quantitative agreement between experiment and theory is achieved only when the clusters accommodate an unusually high oxygen content, with metal-to-oxygen ratios reaching up to Mo:O = 1:5, far exceeding the 1:3 limit of bulk oxide MoO3. This superstoichiometric regime is a consequence of coordination plasticity, where the molybdenum framework undergoes pronounced structural expansion to stable tetrahedral MoO4 motifs that are energetically inaccessible in extended solids. We provide compelling evidence that this process is mediated by photon-driven structural fluxionality: with kinetic energies exceeding 10 eV, secondary electrons generated during photoemission represent the only source to provide the vibrational excitations necessary to overcome the thermal constraint for structural transformation, allowing the clusters to disrupt the atomic connectivity and reach low-energy isomer configurations characterized by large structural expansion. Furthermore, atomic valence, rather than formal oxidation state, provides a physically meaningful and transferable descriptor for interpreting the main trend in core electron binding energy shifts in nanoscale disordered systems. These findings reveal a fundamentally non-bulk oxidation mechanism governed by non-thermal energy-activated structural dynamics, outlining a strategy for engineering oxygen-rich reactive sites at the ultimate size limit.

4. Covalently Self-Polymerized Bioactive Poly(dopamine-silicon) Nanoplatform Reprograms Macrophage Metabolism, Modulates Redox Homeostasis, and Promotes Efficient Angiogenesis for Inflammation Injury Repair.
4. 共价自聚合生物活性聚（多巴胺-硅）纳米平台重编程巨噬细胞代谢、调控氧化还原稳态并促进高效血管生成以修复炎症损伤PMID:日期:2026-09-08The inflammation-related tissue injury repair is still a challenge, in which the metabolic disturbance of macrophages induces cascade amplification of inflammatory mediators and hinders tissue repair. Herein, we developed covalently self-assembled poly(dopamine-silicon) nanoparticles (DS NPs) that integrate enzyme-mimetic catalysis with bioactive ion release to achieve sequential redox modulation and metabolic immune regulation in infected wounds and lung injury models. The covalent linkage reorganized dopamine into a stable amorphous network, preventing π-π stacking and exposing reactive catechol groups, thereby enhancing antioxidant and superoxide dismutase-like activities, which efficiently eliminated reactive oxygen/nitrogen species and corrected oxidative imbalance. Meanwhile, DS NPs supported mitochondrial oxidative phosphorylation and modulated macrophage polarization toward an M2 phenotype with an 89% reduction in TNF-α expression. The immunometabolic reprogramming promoted the transition from inflammation to regeneration, while the sustained release of bioactive silicate ions synergistically promoted angiogenesis by upregulating ANG expression in HUVECs by 2.06-fold. As a proof of concept, in MRSA-infected wound and the early inflammatory stage of acute lung injury models, DS NPs suppressed cytokine overexpression, accelerated re-epithelialization, and restored microvascular integrity. This work demonstrates a biomimetic hybrid platform that can integrate modulation of the inflammatory microenvironment, metabolic reprogramming, and tissue regeneration, offering a promising therapeutic strategy for early intervention in inflammation-associated tissue injuries.

5. Nanoscale Geometrical Patterning for Junctionless Thermoelectrics.
5. 无连接热电材料的纳米级几何图形PMID:日期:2026-09-08Typical thermoelectric phenomena require a junction between two dissimilar or chemically/electrically modified materials with different Seebeck coefficients, where temperature gradients generate a voltage (Seebeck effect) and applied electrical currents induce localized heating/cooling (Peltier effect). Here we show that periodic geometrical patterning alone is sufficient to generate spatially extended thermoelectric responses, such as the Seebeck coefficient, governed by a characteristic thermoelectric relaxation length, without requiring compositional modification or heterojunctions. Specifically, we found that the Seebeck coefficient, the key parameter governing thermoelectric performance, can be engineered over arbitrarily shaped, large-area regions of a uniform two-dimensional (2D) material through geometrical patterning. The modification of the Seebeck coefficient extends exponentially from the geometric discontinuity with a characteristic "decay length", dTE ∼ 0.4 μm. By constructing nanopatterns of voids with pitch smaller than dTE, we effectively achieve a thermoelectric effect without material "junctions", providing alternative routes to manipulate the directionality of thermoelectric response in diverse scaled 2D devices for nanoelectronics, photodetectors, sensors and energy applications.

6. High-Pressure Chemistry toward the Modulation of the Structure and Properties of Nanocrystals.
6. 高压化学对纳米晶体结构与性质的调控PMID:日期:2026-09-08High-pressure chemistry, capable of modulating material structures and properties under extreme thermodynamic conditions, has emerged as a powerful tool for advancing nanoresearch. Semiconductor nanocrystals exhibit distinctive size- and shape-dependent physicochemical properties arising from strong quantum confinement effects. However, conventional ambient-pressure strategies for controlling their structure and luminescent behavior face inherent limitations. This review comprehensively surveys advances in high-pressure nanocrystal research spanning 2016 to 2025, with concentrated coverage of breakthrough discoveries published between 2020 and 2025. Our core scope centers on luminescent nanocrystal systems, namely chalcogenides, core-shell quantum dots, and halide perovskites. To deliver a well-rounded overview, we additionally incorporate relevant progress on ligand-capped nanoparticles and magnetic Fe3O4 nanocrystals. The discussion is organized into five interrelated thematic modules: (i) pressure-induced structural phase transitions; (ii) pressure-regulated nanocrystal morphology and assembly; (iii) pressure-driven surface engineering of nanocrystals; (iv) pressure engineering of core-shell nanocrystal interfaces; and (v) pressure-induced emission. We elucidate the regulatory mechanisms of high pressure, including the modulation of structure, enhancement of surface interactions, optimization of interfacial coupling, and formation of self-trapped excitons (STE). Additionally, this review highlights the application of high-pressure techniques in resolving long-standing ambient-pressure controversies in nanocrystal luminescence mechanisms. Finally, the challenges and outlook of high-pressure chemistry toward the modulation of the structures and properties of nanocrystals are summarized. We sincerely hope that this review will provide guidance for the rational design and precise modulation of high-performance nanomaterials, and further promote the cross-development of high-pressure chemistry and nanomaterials science.

7. Beyond Imaging: Localized Synthesis, Fabrication, and Surface Modification via Scanning Electrochemical Cell Microscopy.
7. 超越成像：通过扫描电化学池显微镜实现局部合成、制备与表面改性PMID:日期:2026-09-08Meniscus-confined electrochemical deposition (MCED) enables highly localized material synthesis, transformation, and surface modification. The Perspective highlights scanning electrochemical cell microscopy (SECCM) as a highly versatile MCED platform. While primarily developed for electrochemical imaging, SECCM also functions as a direct-write tool capable of producing complex architectures and probing associated localized electrochemical phenomena. We focus on a concise technical overview to position SECCM within a broader MCED landscape. We then examine its application across key material processes: metal and metal alloy deposition, surface functionalization and reagent delivery, and polymer synthesis. In each case, SECCM not only enables material fabrication or dissolution with high spatiotemporal control but is also capable of revealing nanoscale mechanistic insights from the analysis of the electrochemical response and/or the use of integrated capability, such as complementary microscopy. By framing SECCM as a fabrication platform, this work aims to connect the SECCM and MCED communities and encourage interdisciplinary adoption. We discuss emerging opportunities in device integration, materials design, and fundamental electrochemistry as well as key practical challenges while outlining future directions for expanding the capability of SECCM as a nanoscale manufacturing tool.

8. A Rapid Poly(ethylene glycol)-Assisted Magnetic Isolation Approach for High-Throughput Extracellular Vesicle Isolation and Subsequent Biomarker Analysis.
PMID:日期:2026-09-08Extracellular vesicles (EVs) are crucial mediators of intercellular communication and have the potential to serve as biomarkers for disease diagnosis and therapeutic monitoring. However, most EV isolation methods often require large sample volumes and specialized instruments or involve trade-offs between purity, yield, cost, and scalability. We developed MagPEG, a workflow that combines poly(ethylene glycol) (PEG)-mediated EV aggregation with magnetic beads to provide a simple, reproducible alternative to ultracentrifugation, size-exclusion chromatography, and commercial precipitation kits. Our optimization experiments clarified the PEG concentration, ionic strength, and bead surface chemistry that collectively influence EV aggregation, capture efficiency, and contaminant coprecipitation, allowing us to define conditions that improve purity while maintaining high recovery. Compared with commonly used methods, MagPEG produced EVs with comparable size distribution, EV markers, and proteomic profiles while relying only on standard laboratory supplies. A key feature of the platform is that EVs and EV-associated DNA, RNA, and proteins can be sequentially extracted from the same bead-bound material, reducing sample loss and hands-on time and enabling multiomic analysis for limited clinical or small animal samples. MagPEG is compatible with downstream applications including proteomics, bead-based assays, and miRNA quantification. When applied to human serum, the method supported high-throughput EV proteomic profiling and enabled the identification of Alzheimer's disease-associated protein signatures, illustrating its utility for biomarker discovery. Overall, our results establish MagPEG as a powerful, rapid, scalable, and high-throughput solution for translational applications in biomarker discovery.

9. In Situ Transmission Electron Microscopy Observation of Redox-Structure-Coupled Resistive Switching in High-Entropy Oxide Memristors.
9. 高熵氧化物忆阻器中氧化还原-结构耦合阻变行为的原位透射电子显微镜观察PMID:日期:2026-09-08High-entropy oxides (HEOs) have emerged as potential candidates for resistive random-access memory (RRAM) owing to their structural robustness and highly tunable electronic configurations. In this study, a transition-metal HEO thin film composed of Ca, Ti, Sr, Ta, Nb, and O was integrated into Au/HEO-based RRAM devices that exhibited a low SET voltage, fast switching speed (30 ns), and long data retention time (104 s). The underlying resistive switching mechanism was uncovered by employing in situ transmission electron microscopy to observe the real-time structural evolution under an electrical bias. A localized monoclinic-to-cubic symmetry transition was observed during the SET process. Energy-dispersive X-ray spectroscopy and electron-energy-loss spectroscopy analyses revealed cationic rearrangements and Ti/Nb redox interactions accompanied by the generation of oxygen vacancies. These results establish the redox-structure-coupled mechanism for understanding resistive switching in complex oxides. In addition, the HEO-based memristors exhibit stable switching characteristics and synaptic plasticity, highlighting their feasibility for next-generation memory and neuromorphic applications.

10. Metal-Phenolic Nanocatalysts Block Transient Receptor Potential Vanilloid 1 and Regulate Bone Homeostasis for Arthritic Analgesia and Therapeutics.
10. 金属-酚纳米催化剂阻断瞬时受体电位香草酸亚型1并调控骨稳态用于关节炎镇痛和治疗。PMID:日期:2026-09-08Inflammatory arthritis is a chronic immune disorder characterized by synovial inflammation, pain, and progressive joint destruction, yet most current therapies focus on the regulation of a single pathological process or symptom. In the present work, we report the establishment of self-assembled strontium-caffeic acid nanoparticles (CA-Sr NPs) through metal-polyphenol coordination, which function as an integrated neuro-immune-bone modulator for inflammatory arthritis therapy. By coupling redox catalysis with TRPV1-associated Ca2+ antagonism and Sr2+-enabled osteoregulation, CA-Sr NPs exhibit combined effects of sustained reactive oxygen species scavenging and enhanced regulation of the Ca2+-permeable TRPV1 channel on macrophages and dorsal root ganglion (DRG) neurons, thus repolarizing macrophages from M1 to M2 phenotype and suppressing the pathological Ca2+ influx and neuronal hyperexcitability, respectively. Meanwhile, CA-Sr NPs promote osteoblast activity while inhibiting osteoclast differentiation. In the Complete Freund's Adjuvant-induced murine arthritis model, CA-Sr NPs markedly alleviated multiple inflammatory arthritis symptoms, including joint swelling, pain, and bone erosion. Collectively, this study highlights highly promising therapeutic potentials of CA-Sr NPs for inflammatory arthritis management and broadens the scope of metal-phenolic nanocatalysts toward treating neuro-immune-bone disorders.
