▎ 摘  要

Currently graphene-doped electrospun scaffolds have been a matter of great interest to be exploited in biomedical fields such as tissue engineering and drug delivery applications. The main objective of this paper is to evaluate the effect of graphene on biological properties of PCL/gelatin nanofibrous mats. SEM analysis was conducted to investigate the morphology of the electrospun nanofibers. The in-vitro cellular proliferation of PC12 cells on nanofibrous web was also investigated. Electrospun PCL/gelatin/graphene nanofibrous mats exhibited 99% antibacterial properties against gram-positive and gram-negative bacteria. Drug release studies indicated that the pi-pi stacking interaction between TCH and graphene has led to the far better controlled release of TCH from electrospun PCL/gelatin/graphene compared to PCL/gelatin nanofibrous scaffolds. These superior properties along with an improvement in hydrophilicity and biodegradation features has made the nanofibers a promising candidate to be used as electrically conductive scaffolds in neural tissue engineering as well as controlled drug delivery.
