Abstract: The long-term success of metallic implants in orthopaedic and dental applications is largely determined by their ability to achieve rapid osseointegration, maintain corrosion resistance, and exhibit high biocompatibility. Conventional coatings such as hydroxyapatite and silicate-based bioactive glasses have improved implant performance; however, limitations remain in achieving uniform coatings with controlled porosity and sustained bioactivity. This study focuses on the development of electrospun bioglass coatings for metallic implant substrates, utilizing the electrospinning technique to produce nanofibrous architectures with a high surface-area-to- volume ratio, interconnected porosity, and tunable morphology. The primary aim is to fabricate bioactive glass nanofiber mats directly deposited onto metallic implants, forming a bio-functifonal interface that integrates mechanical stability with superior bioactivity. Electrospinning, traditionally used for polymer scaffold fabrication, offers the unique advantage of generating nanoscale fibers that mimic the extracellular matrix, thereby enhancing cellular adhesion and proliferation. By optimizing process parameters such as voltage, flow rate, and needle–collector distance, followed by post-deposition sintering, the coating is expected to achieve strong adhesion while preserving the structural integrity of bioglass. Comprehensive evaluation includes In-vitro immersion studies in simulated body fluid (SBF) to assess apatite formation, pH stability, and ion release (Ca, P, Si), alongside surface characterization via SEM/EDS, FTIR, and XRD. Biological testing determines cytocompatibility, osteogenic potential, and mineralization behaviour, while mechanical adhesion tests confirm coating robustness under physiological conditions. The expected outcome is to establish electrospun bioglass coatings as a next-generation strategy for biomedical implants, providing a bioactive and mechanically stable interface that enhances osseointegration and reduces long-term implant failure.
