Through the integration of QDs into nanocomposites, a significant enhancement in diagnostic capabilities has occurred, facilitating targeted delivery, signal amplification, and multi-functionality. A platform established on such advancements enables the ultra-sensitive detection of biomarkers at the femtomolar level in complex biological media, expanding applications within cancer diagnostics, infectious diseases, and real-time glucose monitoring.

Aramid fiber-reinforced epoxy resin composites (AFRP) have become an ideal material for high-performance insulating rods due to their lightweight properties and high strength. However, the interfacial weakening effect in AFRP, caused by the low surface energy and chemical inertness of aramid fibers (AF), remains a critical technical bottleneck limiting its engineering applications. This study constructs a honeycomb-like surface structure on AF through the synergistic interaction of 1H,1H,2H,2H-perfluorodecyltrimethoxysilane (FDTS) and SiO2 nanoparticles. By incorporating Al2O3 nanoparticles into the epoxy matrix, the interfacial bonding strength and insulation properties of AFRP are synergistically enhanced. The interfacial shear strength and tensile strength of AFRP increased by 123.02% and 129.13%, respectively, while the breakdown field strength improved by 64.45%. Analysis of micro-nano structural characterization reveals that the interfacial enhancement originates from the combined effects of AF surface modification and Al2O3 doping, which optimize interfacial insulation properties through non-bonding interactions introduced by FDTS, SiO2, and Al2O3.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"69 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 friction properties of nanohybrids composed of one-dimensional (1D) nanotubes and two-dimensional (2D) materials remain challenging to detect experimentally. Herein, we employ atomic simulations to investigate the relationship between friction and deformation in a sandwich structure, where a single-walled carbon nanotube (SWCNT) is encapsulated between graphene layers. The results demonstrate that the nanotube shape transitions from a circular to oval cross section, and eventually collapses as compressive force increases. In the linear elastic regime, the radial stiffness of SWCNT exhibits an inverse cubic dependence on the nanotube radius (K ∝ 1/R3). Concurrently, the rolling ratio in the linear elastic deformation regime is described by a cubic equation. As the nanotubes are squeezed into collapsed states, the motion changes from rolling to sliding. The transition of movement is attributed to the competition between strain energy and adhesion energy. The shear stress remains nearly constant during rolling, while it increases proportionally with normal stress under sliding conditions. Our findings provide deep insights into the linear elastic properties of nanotubes, contributing to their potential applications in reinforced composite materials and the design of rolling superlubricity for nano-electro-mechanical system (NEMS) devices.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144482616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collagen in tissues is exposed to cross-linking processes such as glycation which might cause progressive tissue stiffening. Tissue stiffening might be considered a landmark of aging. Yet a quantitative characterization of the elastic modulus of collagen nanofibers under different cross-linking processes and stages is not available. Bimodal AFM was applied to generate time-lapsed maps of Young's modulus of type I collagen nanoribbons under two cross-linking processes associated, respectively, with the presence of ribose and glutaraldehyde in the solution. Elastic modulus maps were acquired for different incubation times (0, 30 min, 12 h, 24 h and 1 week). The experiments were performed in liquid. The Young's modulus showed an initial sharp increase after an incubation time of 30 min, from a few MPa (native) to 100 MPa. From then onwards we measured a monotonic increase until a saturation value of about 2 GPa was reached after one week. We did not observe a dependence on the elastic modulus evolution using ribose versus glutaraldehyde. The saturation value was very similar to that measured on dry collagen nanoribbons.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"26 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic nMOFs, composed of a magnetic core and MOF coating, can further enhance their functionality through remote control using an external magnetic field. However, only a few studies have investigated the potential toxicity of magnetic nMOFs and the effects of their degradation on cellular machinery and the translation process. Here we show magnetic MOFs that: (i) regulate gene expression through antisense payload delivery; (ii) do not inhibit protein synthesis. We harness a cell-free protein system, CFPS, to investigate gene expression under more controlled conditions compared to traditional cell-based systems. Our findings demonstrate that magnetic nMOFs, with a magnetite core and a MIL-100(Fe) shell, do not inhibit protein translation upon degradation, and nMOFs loaded with antisense oligonucleotides can suppress protein translation by up to 87%. Furthermore, the magnetic nature of nMOFs ensured the fine-tuning of gene expression through remote control via a magnetic field without any additions to the CFPS system, thus offering an additional modality for the \"on/off\" control of cell-free protein synthesis. Considering the promising characteristics of nMOFs as delivery systems with minimal side effects, we anticipate their use in cutting-edge synthetic biology, biomedical applications, and the creation of the next generation of theranostic agents.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"19 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144370419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To represent distinct pH environments, three aqueous electrolytes, namely H2SO4 (acidic), NaOH (basic), and Na2SO4 (neutral), were selected. A range of standard characterization methods, including X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and energy-dispersive X-ray spectroscopy (EDX), were employed to validate the successful fabrication and integrity of the supercapacitive electrode. Electrochemical performance was evaluated through cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS), elucidating the charge storage behaviour of the device at different pH levels. As a result, the fabricated SS device exhibited an impressive electrochemical potential window of 2 V (0 to +2 V) across all electrolytic systems, demonstrating excellent operational stability and pH adaptability. Among the tested electrolytes, the acidic H2SO4 electrolyte demonstrated the highest performance, achieving a high areal capacitance of 123.73 mF cm-2 and an energy density of 68.73 μWh cm-2 at a current density of 1 mA cm-2. Furthermore, the device demonstrated reliable cycling stability, retaining approximately 78.69% of its initial capacitance after 5000 consecutive GCD cycles. These results highlight the critical role of electrolyte pH in tailoring supercapacitor performance and provide valuable insights into the design of high-performance, flexible symmetric supercapacitors through strategic electrolyte selection.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"101 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144370418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While promissing, such demonstrations have so far been limited to model systems, consisting on minimally functionalized aryl radicals. With a growing demand for more sophisticated surfaces, bearing multiple functions, a demonstration of the generality of the strategy to chemically complex moieties and surfaces is deeply needed. In this work, we aim to fill this gap by preparing tetraphenyl porphyrin derivatives modified to become radical precursors that can be activated with light. Operando optical monitoring is used to non-invasively analyze their grafting behavior in different conditions, optimizing the routes to enable modification of inert glass surfaces with high precision (30 atto L). We demonstrate that the methodology is compatible with direct laser writing technologies, and use it to prepare photophysically active surfaces with high resolution. We demonstrate that the instrinsic emissive properties of Tetraphenylporphyrin derivatives are well preserved, and that several surface modifing steps can be sequentially stacked, leading to the preparation of surfaces with mulitple functions. By controlling the microscale distribution of chemical groups with different photophysical properties, we demonstrate that complex chemical designs can be readily and reliably implemented. This work therefore shows that light activated radical pathways can be broadly used to modify surfaces, opening interesting new perspectives for the implementation of functional materials.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"636 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144370819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
