Short gap of the peripheralnerve damage recover very slowly and if the gap between transected nerve ends is large, self- recovery becomes impossible. Hence, repair andregeneration strategies of peripheral nerve injuries have taken a great deal of consideration.Materials and Methods: In this study, a novel neural scaffold was produced by combining graphene oxide (GO) with polylactic acid (PLLA) toproduce electrospun nanofibers to enhance physical, chemical and biological properties of currently used scaffolds.Results: The produced GO/PLLA nanofibers had a tensile modulus of 381 MPa and 10 MPa tensile strength. These values were found to be similarto the mechanical properties of peripheral nerve tissue. Biocompatibility studies also demonstrated that the produced biomaterials contributed tonerve tissue growth.Conclusion: This study shows that GO/PLLA based nanofibers show potential for the regeneration of nerve tissue.</p></abstract>

                            <p>Amaç: Periferal sinir hasarı ciddi bir sağlık sorunu olup hastanın hayat kalitesini ciddi olarak etkilemektedir. Periferal sinir hasarı çok yavaş iyileşirve iki sinir ucu arasında mesafe çoksa, hiç iyileşemez. Bu sebeple, sinir hasarının tedavisi için farklı stratejiler geliştirilmektedir. Bu çalışmalargrafen oksit (GO)/polilaktik asit (PLLA) bazlı sinir iskelelerinin gelişmesini sağlamıştır. Bu iskeleler ile biyomalzemenin fiziksel, kimyasal ve biyolojiközelliklerinin geliştirilmesi hedeflenmiştir.Gereç ve Yöntem: Bu çalışmada, GO PLLA içerisine ilave edilmiştir ve elektroeğirme yöntemiyle matlar üretilmiştir. Daha sonra üretilen malzemelerinmekanik özellikleri ve biyouyumlulukları test edilmiştir.Bulgular: Üretilen GO/PLLA nanofiberler 381 MPa çekme modülüne ve 10 MPa çekme kuvvetine sahiptir. Bu değerler sinir dokusunun mekaniközelliklerine çok yakındır. Biyoyumluluk çalışmaları da üretilen biyomalzemelerin sinir hücresi gelişimine katkı sağladığını göstermiştir.Sonuç: Yapılan çalışmalar GO/PLLA bazlı nanofiberlerin sinir dokusu rejenerasyonu için ümit vaad ettiğini göstermiştir</p></trans-abstract>
