This study presents the fabrication and evaluation of multifunctional electrospun polycaprolactone (PCL)-based scaffolds incorporating silver vanadate (AgVO<sub>3</sub>), hydroxyapatite (HAp), and graphene oxide (GO) for advanced wound care applications. AgVO<sub>3</sub> offers potent antibacterial properties, HAp supports osteogenic and regenerative activities and GO enhances both mechanical performance and cellular interactions. The scaffolds exhibited a highly porous nanofibrous structure, mimicking the extracellular matrix (ECM) and promoting cell attachment, migration, and nutrient exchange. Comprehensive physicochemical characterization using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, and field-emission scanning electron microscopy (FE-SEM) confirmed the successful integration of the composite. Mechanical testing revealed that GO-containing scaffolds significantly improved stiffness, with AgVO<sub>3</sub>/GO@PCL and HAp/GO@PCL achieving Young's moduli of 5.82 MPa and 4.36 MPa, respectively, which are substantially higher than that of neat PCL (1.39 MPa).

This study aimed to prepare SrTiO<sub>3</sub> nanostructures with varying Sr content on the surface of titanium through a thermal-chemical treatment, enhancing the osteogenic capacity of titanium while providing antibacterial properties. The results indicated that the SrTiO<sub>3</sub> nanostructures are primarily composed of pure titanium and SrTiO<sub>3</sub> phases, exhibiting a rod-like surface morphology. Sr is uniformly distributed across the surface of the samples, and increasing the Sr content does not alter the morphology of the nanostructures. Wettability tests demonstrated that the SrTiO<sub>3</sub> nanostructures exhibited superhydrophilicity, promoting cell adhesion. Electrochemical tests revealed that the SrTiO<sub>3</sub> nanostructures prepared on the titanium surface significantly enhanced its corrosion resistance. After 14 days of immersion in simulated body fluids, a significant amount of hydroxyapatite formed on the surface of STN3, indicating that the SrTiO<sub>3</sub> nanostructures possess good bioactivity. In vitro antimicrobial tests demonstrated that SrTiO<sub>3</sub> nanostructures were effective against both Escherichia coli and Staphylococcus aureus, with the antimicrobial rates increasing alongside the Sr content, reaching 48.1% and 38.6%, respectively.</p>","PeriodicalId":647,"journal":{"name":"Journal of Materials Science: Materials in Medicine","volume":"36 1","pages":"54"},"PeriodicalIF":4.2,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144473652","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}
