Herein, we verify that the FAP+αSMA+ CAFs subtype in the 4T1 murine model effectively recapitulates its counterpart in human triple-negative breast cancer (TNBC), demonstrating strong tumor-promoting activity. We specifically engineer these CAFs in situ to enhance antitumor immunity using an innovative nanodrug, IL-15 plasmid-loaded FAP-sensitive MgCa/z-Gly-Pro-pamidronate acid nanoparticles (PN/MCG NPs). PN/MCG NPs can reverse the tumor-promoting phenotype of FAP+ αSMA+ CAFs and engineer FAP+ αSMA+ CAFs to sustain IL-15 expression. These engineered FAP+ αSMA+ CAFs significantly reduce the tumor immune suppression. Gene set enrichment analysis (GSEA) reveals enhanced immune cell proliferation and activation. Furthermore, we also prove that FAP+ αSMA+ human mammary fibroblast cells (FAP+ αSMA+ HMFs) also can be engineered by PN/MCG NPs in vitro.

Cognitive impairment is a common and debilitating complication of traumatic brain injury (TBI), yet its underlying mechanisms remain poorly understood and effective clinical interventions are lacking. In this study, we observed persistent cognitive deficits in a mouse model of TBI, a phenomenon that has been widely documented in previous studies, and importantly, we found that these impairments were closely associated with increased hippocampal NSCs (H-NSCs) senescence. To investigate the cause of NSCs' senescence, we analyzed cerebrospinal fluid samples from TBI patients and hippocampal tissues from TBI mice and identified persistently elevated levels of IL-1β post TBI. In vitro, IL-1β successfully induced NSCs' senescence and suppressed neurogenesis. Induced pluripotent stem cell-derived small extracellular vesicles (iPSC-sEVs) reversed IL-1β-induced senescence and restored neurogenic potential in H-NSCs. In vivo, iPSC-sEVs alleviated cognitive deficits and H-NSC senescence after TBI. Integrated proteomic and NSC cell transcriptomic analyses revealed that the β-catenin/ID2/CDKN2B (p15INK4b) signaling axis plays a critical role in regulating H-NSC senescence, which was further validated through inhibitor experiments. In summary, our findings demonstrate that iPSC-sEVs attenuate NSC senescence and improve cognitive function following TBI via modulation of the β-catenin/ID2/CDKN2B (p15INK4b) axis.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"58 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145339011","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}

Moreover, a large-scale P(ANI-AA)-CoFe/NiO/BiVO4 system sustains a photocurrent of 27 mA with 500 h long-term operational stability at 1.1 V vs RHE, outperforming previously reported PEC systems.

Dual-gate and gate-all-around geometries are often employed to improve gate control in very short channel length transistors. This can introduce significant process complexity to the device fabrication compared to that of single-gate transistors. It is shown in this paper that substantial reductions in short channel effects are possible in single-gate FETs with indium gallium zinc oxide semiconductor channels by modifying the design of the source and drain electrodes to possess an array of tapered tips that are designated as nanospike electrodes. FETs with channel lengths of 20-25 nm and nanospike electrodes have DIBL and other key metrics that are comparable to those in much larger (70-80 nm) channel length FETs with a conventional source/drain electrode design. These improvements stem from better gate control near the source and drain electrode tips due to the shape of these electrodes. These bottom-gate FETs had a gate insulator consisting of a 9 nm thick Al2O3 and independent Ni gates. This design approach is expected to be very helpful for a variety of semiconductor technologies being considered for back-end-of-line applications.

In this study, we demonstrate a near-field approach for probing and modulating dark exciton-plasmon hybrid states through planar plasmonic nanostructures at room temperature. The designed meta-structure from the hole array on Au films generates surface plasmon polariton (SPP) interference hotspots with precisely controlled out-of-plane electric fields, enabling direct access to dark exciton and coupled states in monolayer WSe2. By integrating transmission-mode scanning near-field optical microscopy with in situ photoluminescence spectroscopy, we achieve simultaneous spatial mapping and spectral characterization of dark exciton-SPP hybrid states. We further propose the \"quantitative modulation via spacer thickness\" theory and approach, which quantifies the system's ultimate coupling capability and enables precise control over both the coupling strength and relative luminescence intensity of dark excitons. Our stress-free planar open cavity design provides a simple yet versatile platform for scalable excitonic devices, such as on-chip lasers and valleytronic systems.

Herein, Fe3O4 nanoparticle enantiomers were synthesized to clarify the concept of chirality-selective neuromodulation, followed by mechanistic investigation. Nerve scaffolds loaded with different Fe3O4 enantiomers were implanted into rat models of PNI or DPN, followed by functional and morphological assessments. Transcriptomic and experimental analyses indicated that dextrorotatory Fe3O4 enantiomers (D-Fe3O4) were endocytosed by Schwann cells, promoting their proliferation, migration, and differentiation into the remyelinated phenotype through the autophagy-driven p-JNK/EPHA5 pathway. Furthermore, implants loaded with D-Fe3O4 exhibited more rapid structural reconstruction along with better sensory and locomotive restoration in the PNI and DPN models. The functional neural repair achieved through D-Fe3O4 led to maintenance of the morphology of target organs and limb health.

In particular, low power consumption and high reliability induced by ultrathin heterostructures with clean van der Waal interfaces make 2D TMDs highly attractive for flash memory applications. Among the TMDs, tantalum disulfide (TaS2) behaves as a metal with a work function of ∼5.6 eV and readily undergoes oxidation. In this study, we propose a 2D MoS2 flash memory device incorporating the oxidation property of TaS2, which is used for charge trapping. We found that a thickness-controlled high-quality tantalum oxide (TaOx) layer is formed on the surface of TaS2 through time- and temperature-adjusted ultraviolet ozone (UVO) treatments, serving as a tunneling insulator in a charge trapping stack. This approach produces a precisely controlled TaOx tunneling layer, achieving a large hysteresis-to-gate sweep range ratio of 74.3% and a reliable retention with an on/off current ratio exceeding 103 after 10,000 s in a flash memory device with MoS2 channel. Effects of oxide thickness, controlled by temperature during UVO treatment, on charge trapping properties and hysteresis behavior were systematically investigated to obtain the best memory characteristics. Furthermore, the TaOx/TaS2 charge trapping stack is demonstrated to be universally applicable to the other 2D TMD WSe2. These results suggest that the proposed UVO-based self-formation of charge trapping and tunneling layers in 2D metals represents a promising strategy for achieving high reliability and performance in flash memory devices, contributing significantly to advancements in 2D material-based memory technologies.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"23 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351583","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}
