Here, An integrated label‐free surface‐enhanced Raman spectroscopy (SERS) profiling strategy, named m<jats:sup>6</jats:sup>A‐SERS‐profiler, is developed for quantitative transcriptome‐wide m<jats:sup>6</jats:sup>A detection of cellular and serum RNA. The m<jats:sup>6</jats:sup>A‐SERS‐profiler is rationally designed through coupling the plasmonic liquid microparticle‐based label‐free SERS biosensing with the custom deep learning‐assisted spectral analysis of m<jats:sup>6</jats:sup>A methylation signatures. With this m<jats:sup>6</jats:sup>A‐SERS‐profiler, direct identification of SERS spectral signatures of canonical nucleoside monophosphates and N<jats:sup>6</jats:sup>‐methyladenosine 5′‐monophosphate is achieved. The applicability of the m<jats:sup>6</jats:sup>A‐SERS‐profiler is verified by quantifying the m<jats:sup>6</jats:sup>A methylation status of microRNA and natural RNA in total RNA isolated from cancer cells and clinical serums. The results reveal a significant difference in the m<jats:sup>6</jats:sup>A RNA methylation among breast cancer cells of different subtypes and between clinical serums from healthy individuals and breast cancer patients. Moreover, the method can quantitatively track the m<jats:sup>6</jats:sup>A dynamics in cancer cells caused by pharmacological inhibition of the m<jats:sup>6</jats:sup>A methyltransferase. Thus, this m<jats:sup>6</jats:sup>A‐SERS‐profiler holds great promise for transcriptome‐wide quantitative detection of m<jats:sup>6</jats:sup>A RNA methylation to investigate biological functions and dynamics of m<jats:sup>6</jats:sup>A methylation in human diseases.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"658 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669705","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}

The ink formulation, comprising a binary solvent system, controls the evaporation rate and the resulting nanoweb morphology.

Variations in solvent composition and coating temperature influence the bundling behavior of Ag NWs, affecting surface roughness and optical properties. The optimized conditions yield highly transparent, uniquely structured PUTs that exhibit strong resistance to counterfeiting due to their inherent randomness.

Herein, a bifunctional electrophilic host is designed by engineering the electron cloud density to effectively anchor electron‐rich polyiodides. Three configurations are initially screened through density functional theory simulations, which reveal that Si─O bonds can firmly anchor I<jats:sub>3</jats:sub><jats:sup>−</jats:sup> via Si electrophilic centers. Owing to the considerably lower electronegativity of Si (1.90) than that of O (3.44), electrons surrounding Si atoms are strongly drawn toward O atoms, creating Si electrophilic centers.

Here, by considering the specific surface energy of different materials, liquid metal (LM) and carbon nanotubes (CNTs) are combined together as a flexible hinge‐like junction, which can connect the rigid conductive network fabricated with Ag nanosheets. The introduction of LM reduces the contact resistance by 53.2% and suppresses conductivity degradation by 34.4% after 100 bending cycles at 60°, compared to the Ag/CNT ink without LM. Because of the advantage in flexibility, a triboelectric linkage pendulum (TLP) employing non‐contact electrostatic induction tomography is developed. The LM‐derived hinge junctions enhance charge transfer efficiency, converting material properties, surface topography, and spatial features into high‐fidelity order harmonic signatures. A cascaded machine learning architecture decodes these harmonic fingerprints, achieving 94.5%–99.5% recognition accuracy for material composition, 3D contours, and submillimeter positional shifts. This work establishes an approach of mechano‐responsive interfacial hinging in nanocomposites, bridging the gap between flexible electronics and AI‐enhanced industrial sensing.

These defects significantly hinder the efficiency and stability of perovskite solar cells (PSCs), posing a major obstacle to their commercialization. Herein, a bifunctional ligand, N‐hydroxymethyl succinimide (NHMS), containing both Lewis base groups (C═O) and proton donor groups (─OH), is introduced to improve the crystal quality of perovskite films and enhance photovoltaic performance. Theoretical calculations and experimental results reveal that NHMS effectively passivates bulk and interfacial defects by coordinating with uncoordinated lead ions (Pb<jats:sup>2+</jats:sup>) and forming hydrogen bonds with iodide or formamidinium ions (I<jats:sup>−</jats:sup>/FA<jats:sup>+</jats:sup>). This dual‐site passivation effect effectively reduces trap‐assisted recombination. Moreover, the incorporation of NHMS promotes the oriented crystallization of the perovskite, leading to a notable increase in grain size. Consequently, NHMS‐treated PSCs achieved a champion power conversion efficiency (PCE) of 26.51% (certified 26.35%), while centimeter‐sized PSCs exhibit an impressive PCE of 25.15%. Furthermore, the NHMS‐treated device exhibits a remarkable stability for maintaining 95% of its initial efficiency after 1100 h of maximum power point voltage tracking.

However, conventional acoustic sensors suffer from various limitations: capacitive and piezoelectric sensors exhibit narrow bandwidth and low sensitivity and rely on external power, while optical sensors, despite their high sensitivity, require complex instrumentation and high costs. Here, an ultra‐wideband acoustic sensor (UWAS) is presented that operates via hybrid triboelectric‐piezoelectric coupling and integrates a trapezoidal‐grooves acoustic metasurface lens (PTGs‐AML). The periodic trapezoidal grooves significantly enhance acoustic radiation, increasing it by up to 255% at 10 MHz compared to conventional rectangular grooves. This enhancement improves acoustic focusing and suppresses sidelobe effects. The UWAS delivers a broad frequency response (20 Hz–50 MHz), high sensitivity (11.3 V Pa<jats:sup>−1</jats:sup> at 60 kHz), and a signal‐to‐noise ratio of 67 dB (at 150 kHz). Its response is frequency‐dependent: omnidirectional at 53 Hz, unidirectional at 50 kHz, and multidirectional at 13 MHz. The enhanced energy localization enabled by PTGs‐AML supports high‐fidelity audio recording, environmental noise monitoring, and biomedical imaging, including venous thrombosis detection and knee effusion diagnosis. This self‐powered and scalable sensor provides a low‐cost solution for diverse acoustic applications.

The nanoscale pore effect of the MOF, combined with the modulating influence of coordinating atoms on the pore walls toward cations and anions, results in a significant impact of the solid electrolyte's pore size on ion transport. In article number 2420572, Wei Zhou, Wenhuan Huang, and co-workers synthesize two zinc-based azole hybrid frameworks (AHF) featuring pillared 1D channels. The refined MOFs with pillared 1D channels present a promising strategy for developing advanced solid-state gel polymer electrolytes for highly efficient sodium-metal batteries.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"35 29","pages":""},"PeriodicalIF":18.5,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adfm.70417","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
