Tissue engineering is defined as the designing and engineering of structures to rebuild and repair a body damaged tissue. Scaffolding Poly Hydroxy Butyrate Valrate (PHBV) has shown good biocompatibility and biodegradable properties. Nanofibers have improved the performance of biomaterials, and could be considered effective. One of the important methods for designing nanofiber scaffold is the electrospinnig method. In this study , PHBV nanofibers were well designed. The samples were evaluated by SEM, contact angle and finally, cell culture. The SEM images showed the size average of nanofibers as to be about 280 nm. Contact angle analysis showed 67 degree for nanofibers and 86 degree for normal films. Cellular investigations (USS cells) showed better adhesion and cell growth and proliferation of nanofiber surfaces than normal samples.
