Electrospinning: Single‐Step Approach to Tailor Surface Chemistry and Potential on Electrospun PCL Fibers for Tissue Engineering Application (Adv. Mater. Interfaces 2/2019)

Electrospun polycaprolactone (PCL) fibers show extensive filopodia formation wrapping the fibers after 3 days of cell culture, which is observed on this SEM micrograph. PCL fibers are electrospun with negative voltage polarities to obtain higher surface potential and enhance the bone tissue regeneration.
