To address these limitations, an injectable nanoenzyme hydrogel composed of a dopamine (DA)-modified hyaluronic acid (HA) scaffold and a graphdiyne-iron (GDY-Fe) complex, named GDY-Fe@HA-DA, exhibits excellent tissue adhesion, self-healing, antibacterial properties, and biocompatibility. Under near-infrared laser irradiation, GDY-Fe@HA-DA effectively eradicates a variety of pathogens, including Escherichia coli, Staphylococcus aureus, and Porphyromonas gingivalis, through a synergistic combination of chemodynamical and photothermal therapies. The hydrogel's efficacy is further validated in both bacterial-infected skin wounds and rat periodontitis models. It effectively alleviates the inflammatory environment and promotes wound healing and periodontal tissue recovery.

Initially triggered by bacterial infection, it is characterized by subsequent dysregulation of mitochondrial homeostasis, leading to ongoing loss of periodontal tissue. Mitophagic flux, a critical physiological mechanism for maintaining mitochondrial homeostasis, is compromised in periodontitis. Additionally, increased release of reactive oxygen species (ROS) exacerbates mitochondrial damage. In this study, a ginsenoside Rd (Rd)-loaded antioxidative polymersome (RdAP) is designed, which is self-assembled from a mitochondrial-protective and ROS-scavenging block copolymer, poly(ethylene oxide)-block-poly(phenylboronic acid pinacol ester-conjugated polylysine) (PEO<sub>113</sub>-b-P(Lys-PAPE)<sub>60</sub>). The phenylboronic acid pinacol ester (PAPE) segment exhibits excellent ROS-responsive properties, enabling effective ROS scavenging through antioxidant production. Rd significantly enhances mitophagic flux by 2.5-fold in periodontal ligament stem cells (PDLSCs) under oxidative stress. Together with the antioxidative polymersome, RdAPs restore mitochondrial homeostasis and enhance the osteogenic capacity of PDLSCs, bringing it closer to that of healthy controls. In a mouse model of periodontitis, the bone mass in the RdAP-treated group is 1.37 times greater than that in the untreated periodontitis group. Overall, the findings propose a novel strategy for addressing refractory periodontitis, which may also be applicable to other diseases characterized by mitochondrial homeostasis imbalance.</p>","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e2403817"},"PeriodicalIF":10.0,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, there is a pressing need to develop effective antibacterial and lubricative coatings on the surface of urinary catheter. In this work, a facile volatilization film-forming method is used to construct coatings on catheter surfaces. Xanthan gum (SR), which has good lubricative and antifouling properties, is oxidized to cross-link with multi-amino compounds, gentamicin (GS), and gelatin, to fabricate uniform coatings on silicone catheters (SR-GXGs). The structures of SR-GXGs are regulated by the components of the film formation solutions. The bacterial metabolism can produce an acidic micro-environment that can regulate GS release to achieve on-demand administration. SR-GXG2 can eliminate 99.99% of common pathogenic bacteria and reduce the dynamic friction coefficient by 98.73%, and showed high stability in a 7-day flowing experiment. In addition, the universality of this method is demonstrated on various kinds of matrices with different shapes, including commercial urethral catheters.
