Here, we show the effect of several types of 20 nm particles on Ca2+ in the presence of shear stress in human umbilical vein endothelial cells (HUVECs), human coronary artery endothelial cells (HCAECs), and human cardiac microvascular endothelial cells (HMVEC-Cs). Intracellular Ca2+ levels increased by nearly three-fold in these cell types upon exposure to 100 μg mL−1 20 nm Au particles, which was not seen in response to larger or smaller particles. An antagonist to the calcium channel – transient receptor potential vanilloid-type 4 (TRPV4) – drastically reduced the amount of calcium by 9.3-fold in HUVECs exposed to 0.6 Pa shear stress and 100 μg mL−1 20 nm gold particles, a trend upheld in both HCAECs and HMVEC-Cs. Cell alignment in the direction of fluid flow is a well-known phenomenon in endothelial cells, and interestingly, cells in the presence of 20 nm particles with fluid flow had a higher alignment index than cells in the fluid flow alone. When compared with previous works, these results indicated that 20 nm particles may be inducing endothelial permeability by activating the TRPV4 channel in vitro. The potential of nanoparticle delivery technologies hinges on an improved understanding of this effect toward improved delivery with limited toxicity.","PeriodicalId":65,"journal":{"name":"Biomaterials Science","volume":" 10","pages":" 2728-2743"},"PeriodicalIF":5.8,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143794106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fortunately, these challenges can be addressed using MnO2-based nanomaterials. In this study, we have designed and synthesized a Curcumin/MnO2@PLGA@4T1 cell membrane (CMP@4T1m) system aimed at remodelling the TME and enhancing sonodynamic immunotherapy for breast cancer. Through the homologous targeting ability of 4T1m, CMP@4T1m efficiently accumulates at the tumor site. Upon ultrasound irradiation, curcumin (Cur) acts as a sonosensitizer, generating cytotoxic reactive oxygen species (ROS) that induce immunogenic cell death (ICD), activate T-cell responses, and repolarize protumoral M2-like macrophages to antitumoral M1-like macrophages. In the TME, which is mildly acidic and enriched with GSH and H2O2, MnO2 not only oxidizes GSH to glutathione disulfide (GSSG) but also reacts with H2O2 and H+ to produce oxygen, alleviating hypoxia and significantly enhancing the sonodynamic immunotherapy effect. Additionally, Mn2+ generated during this process converts H2O2 into cytotoxic hydroxyl radicals (˙OH). This study thus lays the foundation for advancing cancer nanomedicine, offering a novel approach that integrates TME remodelling with sonodynamic immunotherapy.","PeriodicalId":65,"journal":{"name":"Biomaterials Science","volume":" 10","pages":" 2767-2782"},"PeriodicalIF":5.8,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present a first-reported microsphere-templated strategy that synergizes microfluidic precision with BCP assembly to overcome these constraints. By engineering emulsion templates via flow rate, BCP concentration and collection distance optimization, we established a method based on the radius-square law governing the evolution of uniform vesicles (size range diameter: 70–170 nm, PDI: 0.16), enabling on-demand size tuning, a capability unattainable with traditional approaches. Multi-scale characterization (DLS, OM, SEM and TEM) elucidates the non-equilibrium templating-to-vesicle transition, revealing critical dynamics of BCP film reorganization. The resultant nano-scale vesicles exhibit rapid cellular uptake (>95% in 3 h) by HUVECs and 4T1 cells with exceptional biocompatibility (>85% viability, 36 h), outperforming many cytotoxic counterparts. This work not only provides a scalable platform for precision vesicle fabrication but also establishes foundational principles for templated self-assembly, bridging microfluidics and soft matter science.

However, its susceptibility to biofouling limits its utility in healthcare. To address this challenge, this study explores the incorporation of gallic acid, a phenolic acid with potent antimicrobial and antithrombotic properties, into BNC membranes. Additionally, a novel drying method termed gradual freezing is introduced, resulting in a directionally-aligned BNC membrane with enhanced mechanical integrity and high porosity. Using glycerol as a solvent and plasticizer, gallic acid was loaded into air-dried BNC (AD-BNC), freeze-dried BNC (FD-BNC), and gradually-frozen BNC (GF-BNC) membranes. Successful drug-loading into FD-BNC and GF-BNC significantly increased the elasticity of the films, however mechanical testing indicated that GF-BNC and its gallic acid/glycerol loaded counterpart (GF-GG-BNC) achieved overall optimal mechanical strength and elasticity. These samples were selected for further antifouling testing. Antibacterial assays demonstrated the practical efficacy of GF-GG-BNC in inhibiting the proliferation and biofilm formation of E. coli and S. aureus, while favorable antithrombotic behaviour prevented clot formation and red blood cell adhesion on the material's surface when compared to GF-BNC membranes. These findings highlight the potential of GF-GG-BNC as a multifunctional biomaterial for the prevention of biofouling in biomedical applications.","PeriodicalId":65,"journal":{"name":"Biomaterials Science","volume":" 10","pages":" 2673-2689"},"PeriodicalIF":5.8,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/bm/d5bm00176e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structure–activity relationship studies were performed to screen out the carriers capable of efficient mRNA delivery and with potential for tumor therapeutic applications. In vivo biodistribution experiments in mice revealed that the lipidoid OEs-K, containing both hydroxyl and ester groups in its linkage, exhibited high mRNA delivery efficiency and lymph node-targeting properties. Using a subcutaneous EG.7-OVA tumor model in mice, the delivery of tumor antigen OVA mRNA using the lipidoid material was evaluated for its antitumor immunotherapeutic potential. Results demonstrated that LNPs formulated with OEs-K promoted dendritic cell uptake in lymph nodes, effectively activated immune responses, and inhibited tumor growth.

By design, these biomaterial platforms can enhance drug bioavailability and site-specific delivery while reducing off-target toxicities when compared to other conventional formulations. By incorporating biocompatible and biodegradable polymers with tunable degradation rates, such as acetalated dextran (Ace-DEX), drug-loaded nanofibers can enhance the safety and efficacy of treatment regimens while improving patient compliance through controlled release. Despite these benefits, clinical translation of electrospun formulations is challenged by labor-intensive in vitro studies for ensuring that release kinetics are accurately characterized and reproducible. In this study, we report a novel workflow for assessing in vitro drug release from Ace-DEX nanofibers using machine learning (ML) and develop a predictive model to streamline this rate-limiting step. The developed Gaussian process regression (GPR) model was trained, validated, and optimized using in vitro release profiles from thirty electrospun Ace-DEX scaffolds.

The mechanisms underlying the formation of dental coatings were elucidated through a combination of structural, microstructural, and spectroscopic analytical methods, including synchrotron infrared nanoimaging. Additionally, the antimicrobial effects of these coatings were investigated. It has been demonstrated that the deposition of an organomineral layer, based on polymerized dihydroxyquinoline, on the surface of natural enamel leads to the agglomeration and orientation of hydroxyapatite nanocrystals within the coating. This process enables the layer to replicate the mechanical properties of natural enamel, resulting in a microhardness value that closely resembles that of natural enamel. Using synchrotron s-SNOM, it has been established that the biomimetic organomineral layer possesses the morphological structure of a poly(2,2,4-trimethyl-1,2-dihydroquinoline-6,7-diol (TMDHQ))/nano-cHAp composite film, which is homogeneously distributed and tightly packed on the enamel surface.
