Currently the most common strategy for transferring substances across the BBB is receptor-mediated transcytosis, which is restricted by several key factors, including insufficient endocytosis by brain microvessel endothelial cells (BMECs) due to underexpressed pinocytotic vesicles, lysosomal retention, and limited exocytosis to the brain parenchyma. We report a hybrid cell membrane (HCM)-coated and 2-methacryloyloxyethyl phosphorylcholine (MPC)-modified nanocarrier to promote drug delivery across the BBB by modulating the transcytosis process. The HCM incorporates a brain metastatic tumor cell membrane for recognition of BMECs and a GFP-293-S cell membrane expressing Spike protein to facilitate membrane fusion between the nanocarrier and BMECs, thereby bypassing vesicle-dependent endocytosis and enhancing cellular uptake. Membrane fusion reduces the chance of lysosomal retention, and MPC modification enhances exocytosis into the brain parenchyma via the interaction of MPC with transporters expressed on the abluminal endothelial membrane. The nanocarrier achieves significantly improved delivery of CuS, a photothermal agent, to the brain and thus enables highly efficient therapy of brain glioma.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"61 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776150","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}

However, to date, most OMHs have been synthesized through the trial-and-error method, and it remains a big challenge to control the molecular-level structures through directed synthetic approaches to rationally optimize luminescence properties. In this work, we proposed a crystal structure modulation strategy to control the dimensionality and optical properties of OMHs by increasing the packing density of Pb-Br octahedra via altering the precursor stoichiometry.

Additionally, the synthesis of compounds from the T series and P series with different dimensionalities further verifies the general applicability of this strategy. This strategy enables the directed control of the structure and optical properties of LD-OMHs while preserving the functionality of organic cations, and paves an avenue for designing and synthesizing LD-OMHs with functional coordination between organic cations and inorganic polyhedra.

The use of soluble redox mediators (RMs) can usually reduce the high charging potential of Li-O<sub>2</sub> batteries, but the RM on the cathode side can diffuse to the Li metal anode and react with it, leading to continuous loss of the RM and causing damage to the fragile Li anode interface. So, it is necessary to develop a bifunctional redox mediator (BRM) that can simultaneously reduce the charging potential and protect the Li anode. Herein, we introduced 4-bromomethyl-phenylboronic acid (BPLA) as a BRM. The Br<sup>-</sup> ions can be dissociated from BPLA during cycling and serve as an effective component of RM, thereby significantly facilitating the reduction of charging potential of Li-O<sub>2</sub> batteries. Meanwhile, the boronic acid groups in BPLA have the capability to engage in cross-linking reactions on the Li-metal surface, forming a flexible and continuous solid-electrolyte interphase (SEI) layer. More importantly, the SEI layer contains the reversible dynamic B-O covalent bond, which possesses a characteristic of continuous dissociation and rearrangement. Thereby the SEI layer possesses the shape adaptability, inhibits the growth of Li dendrites, and suppresses the reaction between RM and Li.
