Monitoring both inhalation and exhalation is crucial for lung function assessment and patient outcomes. However, current sensors lack sufficient stability and also lack the ability to differentiate between inhalation and exhalation, limiting clinical effectiveness. Inspired by bat-wing hair structures, we report an all-optical fiber sensilla for bidirectional airflow detection. Optical Merkel cells and microhairs are integrated at the fiber tip through femtosecond laser 3D nanoprinting. Bidirectional airflow interacts with the hair structures, inducing opposing nanoscale deformations of the Merkel cells, which causes spectral drift in different directions. The device enables bidirectional flow detection with sensitivities of 19.16 nm/(L/min) and −24.46 nm/(L/min), a record-high stability over 10,000 cycles. The ultracompact design allows seamless integration into trachea or masks. The device effectively identifies respiratory patterns, distress signals, and apnea signs, providing a noninvasive and precise tool for CRD management and emergency response.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"16 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672641","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 present two Si QD:anthracene hybrid systems with molecular silane or germane bridges that, for the first time, enable access to an intermediate QD-anthracene coupling regime. We first describe a new surface functionalization approach that uses methyl radical-mediated dehydrocoupling to install aryldialkylsilanes and germanes onto hydride-terminated Si QD surfaces. Transient absorption spectroscopy and density functional theory calculations show these tetrel bridges mediate QD-anthracene coupling strengths that are intermediate between π-conjugated vinyl and nonconjugated ethyl bridges. We optimize the new hybrids in a triplet upconversion system with 9,10-diphenylanthracene emitters and achieve photon upconversion efficiencies of 6.2% and 5.1% for silane and germane systems, respectively. This work shows that main group element bridges can provide access to QD-transmitter coupling characteristics that are distinct from conventional organic bridges.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"2 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672640","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, the inability to identify and track individual microtubules has constrained their applications to ensemble behaviors, limiting their potential for single-entity-based nanotechnologies. To address this challenge, we present a novel method for encoding digital information directly onto individual microtubules using photobleaching patterns. Binary numbers (1 to 15) were encoded within ∼12 μm segments of moving microtubules by photobleaching with a stationary pulsed laser, creating spatial frequency patterns corresponding to distinct bits of information. Fourier analysis enabled the accurate retrieval of the encoded data, demonstrating the feasibility of direct information storage and retrieval on macromolecular structures. This approach offers a transformative solution for recording microtubule trajectories within nanotechnological devices by encoding path information directly onto microtubules at branch points, obviating the need for video-based tracking. We anticipate that this innovation will advance the development of individualized microtubule-based technologies.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"93 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672643","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, the development of nanophotonic circuits utilizing plasmons is strongly hampered by the absence of fundamental building blocks such as long-lived deep-subwavelength plasmons, plasmonic waveguides, and field-effect plasmonic transistors (FEPTs). Here, we demonstrate Luttinger-liquid FEPTs based on metallic–semiconducting carbon nanotube junctions. In these devices, the propagation of plasmon waves across the junction can be efficiently controlled by electrostatic gating. Theoretical analysis and numerical simulations indicate that the reflection/transmission of Luttinger-liquid plasmons at junctions can be captured well by the Fresnel equation. This result suggests that the classical Fresnel law persists for Luttinger-liquid plasmons with a reduced dimensionality. Our study not only uncovers the fundamental propagation characteristics of Luttinger-liquid plasmons at junctions but also introduces a new category of FEPTs that could facilitate the development of high-frequency nanophotonic circuits.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"22 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666572","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}

Exposing specific crystal facets of an electrode material is considered to be an effective strategy to reduce the expansion ratio and ion diffusion barrier. Here, in situ TEM investigations and theoretical calculations indicate that the exposure of (010) facets in Sb2O3 ameliorates the expansion ratio and reduces the Na+ diffusion barrier to enhance reversible Na+ storage. Theoretical calculations also reveal that polyvinylpyrrolidone facilitates the exposure of (010) facets. A facet-engineered Sb2O3 nanobelt with exposed (010) facets (Sb2O3-(010)) demonstrates superior performance, including higher capacity, excellent rate performance, and enhanced cycling stability compared to conventional Sb2O3. Notably, at 60 °C, Sb2O3-(010) shows excellent sodium storage properties and even maintains an 80.6% capacity retention ratio after 200 cycles at 5.00 A g–1.

A spin-flop transition, a typical magnetic reorientation in antiferromagnets, is expected to affect magnon transport, but studies on this topic are still rare and remain challenging, especially for van der Waals materials. Here we demonstrate the unconventional magnon transport driven by an anisotropic spin-flop transition in the van der Waals antiferromagnet NiPS3. Examining the nonlocal voltage from thermally driven magnons reveals sharp jumps at certain directions when an in-plane magnetic field aligns with the b-axis of NiPS3, attributed to an in-plane anisotropic spin-flop transition. Furthermore, the thermally driven magnon signal exhibits a 1/d2 decay in thin NiPS3, evidencing that it is dominated by the intrinsic spin Seebeck effect. Our findings highlight that the electrical detection of magnon currents in a nonlocal device geometry serves as a powerful approach for studying magnetic phase transitions in MIs.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"32 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672653","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}
