This work demonstrated the synthesis of IONPs using the aqueous root extract of Cyperus rotundus, a traditional antibacterial plant source (Cr-IONPs). The synthesized Cr-IONPs were characterized by various analytical instruments DLS, Zeta, XRD, SEM, VSM, etc. to evaluate its physicochemical and magnetic nature. The results confirmed the uniform shape of Cr-IONPs within a size range of 30-70 nm. Additionally, they exhibited excellent colloidal stability with a Zeta potential value of -30.50 ± 1.79 mV. The VSM analysis revealed a superparamagnetic nature with zero remanence value. The antibacterial study showed that Cr-IONPs exhibited strong antibacterial potential in a concentration-dependent manner. Both Pseudomonas aeruginosa (P. aeruginosa) and Staphyllococcus aureus (S. aureus) strains demonstrated that Cr-IONPs exhibit potent antibacterial activity in a concentration-dependent manner. Furthermore, the diameter of the zone of inhibition increased with higher concentrations of the Cr-IONPs. These results demonstrate that the Cr-IONPs synthesized via a greener approach using C. rotundus extract exhibit strong antibacterial activity and biocompatibility, making them a promising candidate as a future antibacterial agent against multi-drug-resistant bacteria. Additionally, their superparamagnetic nature also broadens their potential for biomedical applications, including targeted drug delivery and diagnostics.</p>","PeriodicalId":647,"journal":{"name":"Journal of Materials Science: Materials in Medicine","volume":"36 1","pages":"60"},"PeriodicalIF":4.2,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144706016","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}

This study presents the fabrication and evaluation of multifunctional electrospun polycaprolactone (PCL)-based scaffolds incorporating silver vanadate (AgVO₃), hydroxyapatite (HAp), and graphene oxide (GO) for advanced wound care applications. AgVO₃ 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 AgVO₃/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). In terms of flexibility, HAp/GO@PCL displayed the highest elongation at break (107.54%), indicating exceptional stretchability. The ultimate tensile strength was also enhanced in HAp@PCL (0.80 kJ/m³) and AgVO₃/@PCL (0.88 kJ/m³), highlighting their capacity to resist mechanical stress during application. Contact angle measurements showed that the AgVO₃-HAp/GO@PCL scaffold had the highest hydrophilicity (65.58° ± 5.97), compared to pure PCL (89.89° ± 3.70), indicating improved wettability, which is critical for fluid management and cell-material interactions at the wound interface. In vivo wound healing studies using a full-thickness rat model demonstrated that AgVO₃/GO@PCL scaffolds achieved 50% wound closure within 3 days, while AgVO₃-HAp/GO@PCL scaffolds facilitated complete re-epithelialization by day 14. Histological analysis confirmed enhanced collagen deposition and organized tissue architecture. The scaffolds also exhibited strong antibacterial activity, with large inhibition zones against S. aureus and E. coli.

To address these issues, we integrated CO₃Ap granules with collagen to generate a sponge-like composite. Collagen, typically derived from bovine or porcine sources, is commonly utilized in clinical settings despite the potential for infections, including parasitic zoonosis. For the purposes of this study, we selected fish-derived collagen (FC), which minimizes the risk of zoonotic complications.

Bone regeneration ability was assessed by implanting these composites into critical-size defects in rat calvarial bones for 2-4 weeks using CO₃Ap-G and FC as controls. Radiographic and histological examinations revealed that the bone-regenerative capacity of CO₃Ap-G/FCs was equivalent to that of CO₃Ap-G.
