Abstract

A mix of two synthetic and natural polymers (polyvinyl alcohol and gum tragacanth) blended with tetracycline containing graphene oxide were used to generate electrospun nanofiber scaffolds which can be used as a transdermal drug delivery system. The physicochemical properties of the nanofiber scaffolds were investigated using SEM, FTIR, XRD and tensile tests. The SEM analysis of nanofiber indicated that the diameter of obtained nanofibers was found to below 100 nm. The result of tensile test showed that the addition of graphene oxide increases the mechanical strength of nanofibers. MTT assay was done to investigate the cell viability of the PVA/GT/GO/TCH nanofiber against the normal cell lines (HUVECs), as well as Agar disk diffusion experiments were applied to determine the antibacterial activity. The results of cytotoxicity assay revealed high cell viability of PVA/GT/GO/TCH nanofiber against HUVECs. In the antimicrobial part of this research, this nanofiber composite indicated higher antibacterial effect than other used materials. © 2020 Elsevier B.V.
