Characterization of CS/PVA/GO electrospun nanofiber membrane with astaxanthin

摘要

Tissue engineering has been widely used in regenerative medicine and tissue engineering scaffolds have become a new research direction for periodontal regenerative repair. We aim to develop a biological scaffold material that can support host immunity and promote periodontal regeneration. In this paper, chitosan (CS)/polyvinyl alcohol (PVA)/graphene oxide (GO)/astaxanthin (ASTA) nanofibers membranes were prepared by electrospinning. The nanofibers were characterized by scanning electron microscopy, infrared spectroscopy, mechanical testing, antibacterial testing and cytotoxicity testing. The CS/PVA/GO/ASTA nanofiber membrane had favorable micro-morphology, good mechanical properties and no cytotoxicity. This preliminary study demonstrates that the CS/PVA/GO/ASTA nanofiber membrane can be used for in vivo and in vitro experiments related to periodontal regeneration. The related mechanism of periodontal regeneration will be evaluated in future studies.
