Here, a novel mesoporous nano-pockets strategy is proposed to design high performance universal SERS substrates by precisely capturing target molecules into plasmonic hotspots. This is achieved through utilizing mesoporous silica as nano-pockets for confined growth of short Au thorns on the Fe3O4 core (Fe3O4@sAT@mSiO2), whilst the vertically open nano-pockets structure with nanospace large enough at tips of short Au thorns to capture target molecules through hydroxyl group on the mesoporous surface. The electromagnetic field enhancement obtained from the Au thorns with an average gap size of 3 nm is sufficient to amplify the Raman signal peaks of the trapped molecules. Therefore, the as-prepared Fe3O4@sAT@mSiO2 proves to be ultrasensitive and reliable SERS detection of 15 kinds of drugs, with all limits of detection lower than those reported in the current literature. Moreover, the experimental findings are further corroborated by simulations using the molecular dynamics and finite element method. These mesoporous-confined Au thorn nano-pockets with accessible hotspots promote future use for developing the universal SERS method in various fields.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"13 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143375745","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, its efficiency is often limited by the low concentration of chloride ions (Cl⁻) within tumor cells, and the non-degradability of the noble metal nanomaterials necessarily used in this strategy gives rise to safety concerns. Here, we identify voltage-gated chloride channels (CLC-7) as a potential chloride-regulation target in melanoma and report an enhanced electro-driven dynamic therapy strategy utilizing surface-enhanced PtIr@M nanocatalysts to address above challenges. Under an alternating electric field (AEF), the activation of CLC-7 channel promotes a massive influx of Cl⁻ from the extracellular side and enhances the catalysis of water dissociation on PtIr@M nanocatalysts to generate toxic hydroxyl radicals (·OH). Moreover, PtIr@M with large surface area provides abundant exposed active sites that facilitate electro-driven self-dissociation and followed release of metal Pt ions, thereby inducing the DNA damage. More importantly, this electrically controlled degradation also effectively minimizes the toxicity associated with heavy metal accumulation. It is believed that this electro-propelled ·OH and Pt ions generation for synergetic tumor therapy based on surface-plus PtIr nanocatalyst represents a promising therapeutic strategy characterized by high-efficiency and biodegradability.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"79 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143375565","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}

Especially, the development of adaptive functional oleogel materials is further constrained by weak interactions between the oil and the gel network, along with the high viscosity of oil. Herein, the state self-adaptability of oleogels is enabled by constructing mechanical responsive dynamic covalent networks via ring-opening polymerization of thioctic acid (TA). Mechanically responsive breaking and rebuilding of disulfide bonds endow mechanical force-induced reversible phase transition of poly(TA) oleogels. Mechanical force-induced disulfide bond breakage disrupts the gel network, transforming the gel into a sol state. Once the mechanical force is removed, the rapid bonding of sulfur radicals rebuilds the gel network. Furthermore, this highly generalizable strategy has the potential as a self-adaptive lubricant. Self-adaptive oleogels can exist in a gel or sol state that adapts to whether the machine is running or stopped. Systematic tribological tests confirm the excellent lubricating properties of poly(TA) oleogels and their outstanding performance stability in adapting to changing friction conditions. This adaptive poly(TA) oleogels provides insights for developing oleogel functional materials with dynamic properties, as well as a new strategy for the development of smart lubricating materials.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"79 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143375599","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, inspired by the classical Möbius strip, a threefold Möbius machine made from humidity-responsive agarose films is proposed. A theoretical model is built based on moisture diffusion and developable surface to unveil the mechanisms of curvature-driven rotary motion with shape conservation, and to establish the quantitative correlations between the motion speed and the geometric and environmental parameters to optimize the design under given constraints. As a result, a Möbius machine capable of operating in a constant humid environment for 252 hours is developed. It can also continuously output mechanical work and sense ambient humidity. It is envisaged that T the integration of intelligent structural design principles and physical modeling will push the development of innovative robotic systems to the next level.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"16 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143375601","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, challenges remain, particularly low carrier collection efficiency caused by high exciton binding energy. This study introduces self-powered heterojunction photodetectors (PDs) based on (PEA)2PbI4/ZnPc, enhancing carrier conduction by the configuration of lateral electrodes and regulating carrier/exciton dynamics via the heterojunction design. The PD achieves an impressive detectivity of 1.14 × 1016 Jones, a 770% increase compared to the control, with a detection limit reaching the black-light level of 3 pW cm−2 under 532 nm at 1 V bias. This performance surpasses all previously reported 2D perovskite PDs and is attributed to suppressed dark current and increased photocurrent. The built-in electric field at the heterojunction counteracts part of the forward bias, reducing intrinsic carrier motion in (PEA)2PbI4 in the dark. It also effectively dissociates photogenerated excitons, minimizing radiative recombination under illumination. This allows the device to detect weak light at the black-light level in self-driven mode. Additionally, the heterojunction device extends the detectable wavelength to 980 nm. This PD has been successfully applied in acousto-optic conversion communication, highlighting its potential for low-power, energy-efficient optical communication solutions.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"51 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143375646","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}

To restore functional sensory input, it is necessary to bypass the damaged circuits, which can be achieved by directly stimulating the appropriate sensory thalamic nuclei. However, available deep brain stimulation electrodes do not provide the resolution required for effective sensory restoration. Therefore, this work develops an implantable biohybrid neural interface aimed at innervating and synaptically stimulating deep brain targets. The interface combines a stretchable stimulation array with an aligned microfluidic axon guidance system seeded with neural spheroids to facilitate the development of a 3 mm long nerve-like structure. A bioresorbable hydrogel nerve conduit is used as a bridge between the tissue and the biohybrid implant. Stimulation of the spheroids within the biohybrid structure in vitro and use of high-density CMOS microelectrode arrays show faithful activity conduction across the device. Although functional in vivo innervation and synapse formation has not yet been achieved in this study, implantation of the biohybrid nerve onto the mouse cortex shows that neural spheroids grow axons in vivo and remain functionally active for more than 22 days post-implantation.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"55 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143375746","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 pure red (620–660 nm) PeLEDs as an essential component for display applications continues to be hampered by severe nonradiative recombination. Particularly, the solution fabrication process of perovskites poses a challenge in the fabrication of white PeLEDs, which further hinders their commercialization. Herein, a novel design is reported of high-efficiency hybrid perovskite/organic tandem white light-emitting diodes (POTWLEDs) by integrating bottom pure red (640 nm) PeLED units with top blue OLED units. To optimize device performance, 5-Bromo-2-fluoropyridine (PD) is introduced, featuring strong electronegative groups of C─N and C─F, as a pyridine passivator into pure red PeLEDs to inhibit nonradiative recombination in the perovskites by passivating defects and improving phase purity of perovskite films, which promotes a maximum external quantum efficiency (EQE) of 20.4%. By integrating the optimized red PeLED units with blue OLED units, efficient POTWLEDs are obtained with high EQE values of 25.9 and 23.7% with CIE coordinates of (0.279 and 0.339) and (0.310 and 0.330), respectively.
