Addressing this, the combined regulation of oxidative stress and inflammation through synergistic modalities offers an efficient therapeutic avenue. In this work, we rationally designed and engineered a highly efficient functional nanosystem, referred to as polydopamine nanoparticles doped with arginine and gadolinium ions (AGPDAR-146a), for the targeted delivery of therapeutic oligonucleotides, specifically microRNA-146a (miR-146a), to inflammatory macrophages within atherosclerotic plaques. AGPDAR-146a nanoparticles effectively load and deliver miR-146a, achieving enhanced accumulation in inflammatory macrophages through the specific interaction between miR-146a and class A scavenger receptors. Functionally, AGPDAR-146a nanoparticles excel in eliminating reactive oxygen species and exert anti-inflammatory effects, principally by modulating the nuclear factor kappa-light-chain-enhancer of activated B cells pathway and the interferon regulatory factor 5 protein, consequently helping to reduce and stabilize atherosclerotic plaques. Additionally, the intrinsic T1 magnetic resonance imaging capability of AGPDAR-146a nanoparticles enables real-time visualization of the progression of plaque inflammation. Therefore, the engineered nanosystem not only underscores the therapeutic potential of miR-146a in atherosclerosis but also illustrates a versatile microRNA delivery strategy applicable to various diseases characterized by oxidative stress and inflammation.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"59 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144154253","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}

Alternatively, the voltage control of magnetism (VCM) promises significantly lower energy costs. In the context of VCM, magneto-ionics distinguishes itself by leveraging voltage-driven ion transport as an energy-efficient approach to control magnetic properties, including magnetization, coercive field, and exchange bias (EB). Herein, we demonstrate that the voltage-driven ionic control of CoO antiferromagnetism allows manipulation of the magnetic properties in exchange-coupled ferromagnetic Co. In a “battery-like” device geometry, a 5 nm Co film is precisely oxidized to realize the Co/CoO heterostructure that is interfaced with a solid-state electrolyte and an anode-like Li ion source. The cathode-like CoO layer reversibly converts back and forth between Co and CoO under gate biases, even after 1000 cycles. This subsequently influences magnetic switching in the exchange-coupled Co layer, which is directly revealed by anisotropic magnetoresistance (AMR) in the Co channel. Our findings demonstrate an efficient method of all-solid-state, voltage-driven, highly reversible ionic control on magnetic channels, offering additional dimensions of control and mass integration capability for spintronic applications.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"153 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144154258","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}

Two major caveats for the use of OMVs as vaccines are their biological safety, since OMVs can induce a severe and even fatal inflammatory response and that they are naturally produced in low amounts. In this study, we show that a strategy to induce the production of OMVs applied to the nonpathogenic bacterium Caulobacter crescentus results in a strain with good OMV yields. In comparison with the OMVs derived from Escherichia coli K-12, the OMVs from C. crescentus induce a lower inflammatory response in an in vivo murine model of acute inflammation and in a human cell assay. Also, only minor signs of pain in mice were observed even at high doses. The C. crescentus OMVs can be efficiently loaded with a recombinant protein and induce antibody production against it with an adjuvant effect, indicating that these OMVs are viable vehicles for the presentation of recombinant antigens.

While recent advances have explored the synergistic mechanisms in multiadditive systems, the inherent multifunctionality of single-additive systems remains underexplored. Here, we investigate a biopharmaceutical agent, ambroxol hydrochloride (AMB), with multifunctional groups as a multifunctional perovskite crystallization regulator. The presence of abundant electron-rich moieties (e.g., −OH and −NH2) facilitates efficient passivation of perovskite grain boundaries via multiple coordination bonds (e.g., O:Pb and N:Pb). These functional groups also exhibit a strong propensity to form hydrogen bonds with halogen ions, thereby effectively suppressing the formation of halogen vacancies and inhibiting ion migration. Furthermore, AMB impedes the adsorption of the spacer molecule phenylethylamine (PEA) on the octahedron surface and competes with PEA for coordination sites, thereby promoting the formation of well-aligned layered phases and enhancing exciton transfer efficiency. Consequently, we obtained spectrally stable sky-blue PeLEDs with a high external quantum efficiency of 22.42%. High-quality active-matrix array displays are further demonstrated, achieving precise independent control of each pixel. These displays exhibit superior brightness and color consistency, making them highly promising for advanced optoelectronic applications.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"2 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144154257","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, acidic CO2 electroreduction remains severely constrained by intense competition from the hydrogen evolution reaction (HER) and sluggish CO2 activation kinetics. Here, we report a bismuth (Bi) nanoparticle catalyst with an amorphous surface layer (a-Bi), which demonstrates high catalytic activity and selectivity toward formic acid (HCOOH) formation in acidic electrolytes. The catalyst achieves impressive Faradaic efficiencies for HCOOH production, exceeding 90% over a wide current density range (-100 to -1000 mA cm-2) with corresponding potentials ranging from -1.24 to -1.75 V versus the reversible hydrogen electrode (vs RHE). Notably, the partial current density for an HCOOH reaches an impressive value of more than -900 mA cm-2 at -1.75 V vs RHE. Furthermore, the a-Bi catalyst exhibited stability for over 52 h at high production rates (-500 mA cm-2) alongside a single-pass carbon efficiency of approximately 85%. In situ spectroscopy and theoretical simulation revealed that surface amorphization significantly enhances the adsorption of CO2 and lowers the hydrogenation barrier, thereby accelerating the CO2RR kinetics while effectively suppressing the HER.

This study further investigated the association of ERα expression with the ferroptosis and EMT levels in a cohort of eosinophilic asthma (EA) patients as well as in an eosinophil–epithelial coculture cell model. By loading small interfering RNA (siRNA) into a mesoporous silica nanoparticle (MSN) and then coating the extracted bronchial epithelial cytomembrane (CM), a bronchial epithelial CM home-targeting nanoplatform (siRNA@MSN@CM) was constructed to selectively decrease the ERα expression in bronchial epithelial cells. The targeting effect of bronchial epithelial cells was confirmed in vitro and in vivo, demonstrating the successful targeted knockdown of ERα expression. Silencing ERα in epithelial cells effectively prevented ferroptosis and EMT induced by coculturing with ferroptotic eosinophils.

During the degradation process, cracks in the electrolyte alternately generated from the two electrode/electrolyte interfaces and propagated until shorting. The lithium dendrites filled in the electrolyte cracks but had a greatly reduced filling ratio after the first plating stage; therefore, the cell could continue working for some time after the solid electrolyte was fully fractured by cracks. The compression of the two lithium electrodes mainly occurred in initial cycles where a ca. 4–7 μm reduction in thickness was observed. The mechanical force and electric potential fields were modeled to visualize their redistributions in different stages of cycling.

Here, we demonstrate a scheme for enhanced light–matter coupling by embedding excitonic tungsten disulfide (WS2) within dielectric hexagonal boron nitride (hBN), forming a van der Waals (vdW) heterostructure that optimizes the field overlap and alignment between excitons and optical waveguide modes. To tailor diffractive coupling between free-space light and the waveguide modes in the vdW heterostructure, we fabricate Fourier surfaces in the top hBN layer by using thermal scanning-probe lithography and etching, producing sinusoidal topographic landscapes with nanometer precision. We observe the formation of exciton-polaritons with a Rabi splitting indicating that the system is at the onset of strong coupling.
