The usage of synthetic scaffolds is a promising approach in development of implant materials. In this study we fabricated nanofibrous nonwovens of polyamide 6 (PA-6) by means of electrospinning and performed a systematic characterization with regard to the mechanical and biological performance of scaffold materials. Mechanical strength was assessed by uniaxial tensile testing and biological performance was evaluated by measuring cell viability and qualitative analysis of cellular morphology when human umbilical vein endothelial cells (EA.hy926) or human fibroblasts (HT-1080) were grown on polymeric substrates. While all polymeric materials exhibited an excellent biocompatibility with respect to cell viability, their surface topography promoted the adhesion of endothelial but not fibroblast cells. A better understanding of the physicochemical and morphological material properties with a selective impact on cell adhesion will help to further improve biocompatibility of nonwovens for biomedical applications.
