Traditional bone grafting requires an open surgical approach to the graft application sites with the attendant complications of a large surgical scar, increased pain and a longer post-operative recovery. To overcome these limitations, there is a great need for the development of better bone graft substitutes. In this study, we developed a novel injectable(More)
Electrospun gelatin(Gel) nanofibers scaffold has such defects as poor mechanical property and quick degradation due to high solubility. In this study, the in situ cross-linked electrospinning technique was used for the production of gelatin nanofibers. Deionized water was chosen as the spinning solvent and graphite oxide (GO) was chosen as the enhancer. The(More)
Poly-L-lactic acid (PLLA) nanofibers were fabricated by electrospinning and treated with O2 plasma. The surface properties of PLLA nanofibers before and after plasma treatment were characterized by water contact angle measurement and X-ray photoelectron spectroscopy (XPS). It was found that the hydrophilicity of PLLA nanofibers was improved and the amount(More)
