Abstract
In this research, a blend of poly (vinyl) alcohol (PVA), silk fibroin nanofibers (SF-NFs), hydroxyapatite nanoparticles (HA-NPs), and curcumin nanoparticles (Cu-NPs) were used to design a nanofibrous scaffold (NFS), by electrospun method, for their possible application in bone apatite formation. The prepared nanofibrous scaffold (NFS) was investigated using physicochemical, mechanical, cell viability, etc. The bioactivity test of NFS was evaluated after immersion in SBF (simulated body fluid). NFS from PVA, SF-NFs, HA-NPs, and Cu-NPs exhibited outstanding physicochemical, mechanical, and antibacterial properties. PVA: SF-NFs: HA-NPs: Cu-NPs scaffold excellent antimicrobial performance against E.coli (4.16 ± 0.16 mm) and S.aureus (4.88 ± 0.10 mm). Biocompatibility studies were assessed using human osteosarcoma MG63 cell line, which displayed 100% viable cell presence in PVA: SF-NFs: HA-NPs: Cu-NPs. Based on the characterization, results indicated that they are excellent scaffolds for bone tissue regeneration.
