a Nanofiber fabrication process and scanning electron microscopy (SEM) images of ampicillin-loaded polycaprolactone (PCL) nanofibers with various flow rates and concentrations (wt%). The fabricated nanofibers are denoted as CR (core nanofiber), CS1 (core-shell nanofiber 1), and CS2 (core-shell nanofiber 2). The diameter of the fabricated nanofibers is in the range of 400–700 nm.
