Abstract
Here, we report the synthesis of three-dimensional (3D) polycaprolactone (PCL) nanofiber incorporated with core-satellite platinum nanoparticles (PtNPs, 2-3 nm) coated gold nanospheres (AuNPs, 30 nm) via the simple lactic acid assisted self-assembly electrospinning technique. The Pt-AuNPs nanoparticle in core-satellite form has been prepared by following solution based methods and characterized with TEM, HR-TEM, UV-Visible, and XRD spectroscopic techniques. The surface morphology and structural analysis of 3D nanofiber scaffolds have been performed with FTIR, TGA, FESEM, and HR-TEM analysis techniques and shown the successful preparation of 3D electrospun fibrous structure composed of Pt-AuNPs loaded PCL (PCL@Pt-AuNPs) as a potential biomaterial for bone tissue engineering applications.
