Silk fibroin is fibrous proteins with excellent mechanical properties which are produced by wide group of animals such as Bombyx Mori. Silk fibroin with specific molecular structure can be processed into a diverse set of morphologies. Additionally, biotechnologically produced silk proteins will allow the preparation of a new generation of protein-based bio-polymeric materials with programmed properties for a wide variety of exciting medical applications. In this study, silk protein was extracted from Bombyx Mori’s cocoons and evaluated by FTIR and XRD methods. Results showed sharp amide peaks in 1655 cm-1 and 1530 cm-1 wavelength in FTIR spectrum pattern confirming existence of fibroin. SEM images of the fibers showed continuous fibers with cross-section between 14 to 24 μm. Biocompatibility tests were carried out through seeding osteoblasts cell line G292 on 2D film as well as fibers. Adhesion and proliferation of osteoblasts were investigated by MTT assay which showed no cytotoxicity. Therefore, fibroin appears to be remarkable material for prospect application in biomedicine.
