However, the intrinsic pro-oxidative properties of AuNFs limit their therapeutic efficacy in diabetic wound treatment. To overcome this limitation, a near-infrared plasmonic Au@CDCe nanohybrid system that can enhance antioxidative performance through the synergistic effects of localized surface plasmon resonance-induced photothermal effect and hot electrons is developed. Specifically, AuNFs serve as near -infrared plasmonic exciters, generating hot electrons that are efficiently transferred to cerium-doped carbon dots (CDCe). Combined with mild photothermal effects, these processes synergistically enhance hydroxyl radical scavenging activity, as well as superoxide dismutase- and catalase-mimicking activities. <em>In vitro</em> experiments demonstrate that Au@CDCe effectively protects cells from oxidative damage, and promotes cell proliferation and migration. <em>In vivo</em>&nbsp;evaluations confirm its ability to modulate the immune microenvironment and accelerate diabetic wound healing.&nbsp;This work establishes a new paradigm for modulating the oxidative stress microenvironment through antioxidant gold-based plasmonic nanozymes and provides novel insights into tuning of prooxidant nanozyme into plasmon-enhanced antioxidant nanozyme.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 1","pages":"94908313-94908313"},"PeriodicalIF":0.0,"publicationDate":"2025-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite progress, the therapeutic efficacy of DLNPs remains limited due to the complexity of the in vivo environment. Increasing evidence shows that mechanical cues such as substrate stiffness and fluid shear stress, are closely associated with cellular endocytosis. Yet, the effects of extracellular fluid viscosity have been largely overlooked. In this study, we found that high-viscosity culture medium (8 cP) treatment inhibits the endocytosis of DLNPs in comparison with low-viscosity culture medium (0.7 cP), decreasing intracellular drug concentration and reducing chemotherapy efficacy. Specifically, viscous resistance increased F-actin and vinculin density, thereby enhancing the cellular elastic modulus and membrane tension. Enhanced F-actin and vinculin also promote YAP nuclear translocation, and the translocated YAP functions as a key effector sustaining this mechanically reinforced state. As a result, such mechanical reinforcement raised the energetic barrier required for macropinocytosis and clathrin-mediated endocytosis, making these processes more difficult to occur. Inhibition of YAP abolishes this state and enhances the endocytosis and chemotherapy efficacy that are inhibited by high viscosity. This study suggests that lowering viscosity or inhibiting YAP function may enhance DLNP efficacy, offering new insights into chemotherapy.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 2","pages":"94908314-94908314"},"PeriodicalIF":0.0,"publicationDate":"2025-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147904730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Piezocatalysis technology, which generates reactive oxygen species (ROS) from green reactants like H<sub>2</sub>O and O<sub>2</sub> under mechanical stimulation, offers a promising alternative to traditional disinfection methods such as chlorine and ultraviolet radiation. This study focuses on using perovskite materials as piezocatalysts due to excellent piezoelectric properties, high ROS generation efficiency, and positive surface potential. The positive charge on the surface of the piezocatalysts enhances electrostatic interactions with bacterial membranes, leading to membrane damage induced by ROS. This mechanism demonstrates remarkable bactericidal effects, including inhibition of methicillin-resistant<em> Staphylococcus aureus</em> (MRSA) and <em>Pseudomonas aeruginosa </em>(<em>P. aeruginosa</em>). Notably, the perovskite piezocatalyst retains its disinfection effectiveness after 10 cycles, highlighting its sustainability and reusability. This work uniquely establishes the synergy between positive surface potential and strong piezoelectricity in perovskite materials as a strategy for achieving highly efficient, stable, and reagent-free inactivation of ARB in complex aqueous environments. These findings suggest that perovskite-based piezocatalysis holds great potential as an ideal solution for the bactericidal disinfection of antibiotic-resistant bacteria in complex wastewater system.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 5","pages":"94908301-94908301"},"PeriodicalIF":0.0,"publicationDate":"2025-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147884276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
