Fabrication of a multilayer bioabsorbable composite vascular stent utilizing oxidized starch-FeO nanoparticles and polycaprolactone nanofibers.

Currently, bioabsorbable polymer stents are utilized to mitigate the risk of late stent restenosis in cardiovascular applications. In this context, we propose a novel assembly that integrates polycaprolactone (PCL) nano-fibers and oxidized starch (OS) with iron oxide nanoparticles (IONPs) to create a rigid-swelling scaffold for cardiovascular stents. This study fabricates the nanocomposite (NC) using a combination of electrospinning and electrospray techniques.
