However, most therapeutic strategies address these abnormalities separately, while biomaterials capable of translating pathological metabolic dysregulation into localized biochemical regulation remain limited. Herein, we report MMCoac@ChOx/HRP, a macrophage membrane-camouflaged coacervate microreactor formed via liquid–liquid phase separation (LLPS). The microreactor features a macromolecularly crowded core self-assembled from poly(diallyldimethylammonium chloride) and sulfobutylether-β-cyclodextrin, which enables cholesterol recognition and enrichment of cholesterol oxidase (ChOx) and horseradish peroxidase (HRP). These co-encapsulated enzymes achieve high enrichment efficiencies of 87.5 and 92.1%, respectively, to drive cholesterol oxidation and subsequent NO generation. In simulated body fluid, MMCoac@ChOx/HRP depleted cholesterol levels from 5.0 to 2.9 ± 0.4 mM and generated 12.1 ± 0.8 μM NO within 12 h. In vitro, it significantly attenuated macrophage foam cell formation and promoted endothelial repair. Furthermore, following systemic administration in ApoE–/– mice, MMCoac@ChOx/HRP preferentially accumulated in atherosclerotic aortic plaques, enhanced in situ NO generation, and reduced aortic plaque burden from 27.4 ± 4.5 to 8.2 ± 3.0%. Overall, this study demonstrates a localized metabolic intervention strategy driven by an LLPS-based microreactor. This versatile biomaterial platform effectively modulates the plaque microenvironment, holding great potential for therapeutic interventions against metabolic syndrome.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 41","pages":"55857–55873"},"PeriodicalIF":7.8,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we propose iodine-induced charge transfer of a covalent organic framework (COF) as an effective strategy to achieve fast ion transport and a stable SSE/Li interface. First, the electron-deficient COF skeleton in the I2/COF charge-transfer complex anchors TFSI- anions through enhanced electrostatic interactions, thereby promoting the dissociation of lithium salt to release free Li+. Second, the electron deficiency of COF strengthens its dipole–dipole interactions with PEO, leading to suppressed PEO crystallization and enhanced COF/PEO compatibility. Third, the electron-deficient COF tailors the Li+ coordination environment via weakening the affinity of PEO and COF toward Li+. Consequently, the I2/COF charge-transfer complex accelerates Li+ transport kinetics in PEO-based composite SSEs. Furthermore, the confinement effect of COF toward I2 via charge transfer effectively inhibits the aggressive lithium anode corrosion by I2, resulting in the controlled growth of a stable, robust, and conductive solid electrolyte interface (SEI) rich in LiF and LiI. Thus, the I2/COF charge-transfer complex enables excellent rate capability and cycling stability of the resulting COF/PEO-based composite SSE, maintaining a capacity retention of 88.58% after 1000 cycles at 2 C. This work offers a promising strategy for designing COF/PEO-based composite SSEs for next-generation all-solid-state lithium metal batteries.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 41","pages":"56182–56191"},"PeriodicalIF":7.8,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149100956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Topical application of Mito-Ce to an imiquimod-induced mouse model of psoriasis visibly resolved psoriatic plaques, reduced the PASI score, and reversed epidermal hyperplasia. Beyond local repair, Mito-Ce rebalanced systemic immunity, evidenced by a decline in splenic pathogenic Th17 cells and polarization toward anti-inflammatory M2 macrophages. Transcriptomic profiling further revealed that Mito-Ce broadly reversed the pathological gene expression program, downregulating stress-responsive and phagocytosis-related genes while upregulating genes associated with metabolism, epidermal proliferation, and tissue homeostatic remodeling. These coordinated networks ultimately re-established immune–barrier homeostasis at the molecular level. Collectively, by integrating nanozyme-mediated ROS scavenging with mitochondrial bioactivity, the Mito-Ce hybrid could treat psoriasis through coordinated disruption of the inflammatory cascade, potentially offering a highly effective platform for various chronic inflammatory disorders.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 41","pages":"55976–55987"},"PeriodicalIF":7.8,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149147395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 systematically compare dark electrochemical and illuminated photoelectrochemical anodic etching and thinning of mechanically exfoliated MoS2, WS2, MoSe2, and WSe2 flakes as a function of applied potential, electrolyte pH, irradiance, and oxidation time. In the dark, oxidation initiates at defect-rich flake edges and produces lateral etching without appreciable basal-plane thinning. The oxidation peak potentials exhibit significantly different pH dependences for sulfide- and selenide-based TMDs, revealing chalcogen-dependent oxidation chemistry and kinetics. Under illumination, an additional oxidation regime emerges at lower anodic potentials, in which multilayer n-type MoS2, WS2, and MoSe2 undergo vertical thinning with minimal lateral etching, whereas no thinning is observed for p-type WSe2. This observation, together with strong suppression of thinning by sacrificial hole acceptors, indicates that photogenerated holes accumulated in the upper layers of n-type TMDs drive a photoelectrochemical self-oxidation process. Tuning the bias, irradiance, and oxidation time enables controlled conversion of initially nonuniform multilayer flakes into homogeneous few-layer structures, while focused laser excitation yields spatially localized thinning and patterning. In addition to elucidating stability windows and oxidation mechanisms of TMD photoelectrodes, these results provide a versatile strategy for controllably tuning the thickness and morphology of layered semiconductors.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"56 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a bifunctional Cu+–Ov–Ce3+ interfacial frustrated Lewis pair (FLP) is constructed by loading Cu onto La doping CeO2. La doping introduces additional oxygen vacancies (Ov) and Ce3+ species, thereby enriching the Ov–Ce3+ sites. Systematic characterizations (XPS, EPR, XAS, TPD, in situ FTIR) combined with DFT calculations reveal that Cu+ sites are responsible for α-H elimination to form 6-hydroxyhexanal (6-HA), whereas the cyclization reaction is driven by the FLP composed of Ov–Ce3+ and adjacent lattice oxygen. La incorporation lowers the energy barrier and enhances FLP formation. Under optimized conditions (3 wt % La, 280 °C, weight hourly space velocity of 1.5 h–1), a ε-CL yield of 61.17% is achieved with good stability over 120 h.
