Background and Aim: Bioactive glass has emerged as a novel innovation in materials science, offering extensive potential in biomedical applications. Due to its unique physicochemical and biological properties, it has become a prominent candidate in regenerative medicine. One of the remarkable features of bioactive glass is its intrinsic antimicrobial activity. In this study, cobalt ions were incorporated into a three-layer electrospun scaffold to enhance its antibacterial performance.
Materials and Methods: The scaffold was fabricated using a combination of polyurethane, polycaprolactone, and collagen, blended with cobalt-doped bioactive glass. The scaffold was produced in a three-layered structure through electrospinning. Its structural and biological properties were analyzed using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and cell adhesion assays. Antibacterial assessments were conducted using four bacterial strains, including both Gram-positive and Gram-negative species.
Results: The antibacterial evaluation conducted 24 hours post-bacterial seeding revealed that the fabricated scaffold effectively inhibited bacterial growth around the scaffold area. The results confirmed the scaffold's favorable antibacterial performance.
Conclusion: The findings of this study demonstrated that the incorporation of cobalt-containing bioactive glass into the designed scaffold significantly enhanced fibroblast cell proliferation and viability, while also exerting strong antibacterial effects. Therefore, this scaffold holds great potential as a promising candidate for tissue engineering applications in the repair of damaged tissues.
