|Abstract:||For reasons of high porosity, biocompatibility and biodegradability, polycaprolactone (PCL) nanofibers have been gaining popularity for use in the construction of bio-scaffolds in tissue engineering applications. In this paper, electrospinning method was used to fabricate PCL nanofibers. Uniaxial tensile testing was performed on a single fiber to investigate its mechanical properties at the nano-scale level. Further, Atomic Force Microscopy (AFM) was employed to investigate the surface structure effects on the mechanical properties of the nanofibers. The results show that under tensile loading the Young's modulus of the nanofibers does not exhibit any significant variation with the decreasing fiber diameters. On the other hand, the surface morphology can affect the tensile strength of the nanofibers but not their Young's modulus.|
