ABSTRACT
Nowadays, as the field of neural tissue engineering advances, the fabrication and application of combined structures open a new window of research for the regeneration of nervous system injuries. In this study, chitosan/poly [vinyl alcohol] -carbon nanotube nanocomposites has been exploited as scaffolds. Electrospinning was used to fabricate chitosan/poly [vinyl alcohol] -carbon nanotube scaffolds. Raman spectroscopy and scanning electron microscopy [SEM] was used to evaluate the chemical and physical structure of the electrospun scaffolds. Then, the biocompatibility of the scaffolds was evaluated using MTT assay and Neutral red assay. The results showed that the chitosan/poly [vinyl alcohol] -carbon nanotube nanocomposites have suitable structural and morphological aspects for human brain-derived cells growth and proliferation. Therefore, the cells could maintain their usual morphology while adhering to the surface of the nanocomposites due to an appropriate biocompatibility of the scaffolds. Chitosan/poly [vinyl alcohol] -carbon nanotube nanocomposites could enhance the proliferation of human brain-derived cells due to their proper structure and biocompatibility
