Single‐Step Electrospinning of Bimodal Fiber Meshes for Ease of Cellular Infiltration

Abstract

Bimodal fiber meshes with fiber diameters differing by one order of magnitude, are electrospun in a simple one-step process, using a standard single syringe electrospin setup. The nano- and microfiber meshes combine the benefits of nanofibers (cell adhesion, proliferation) with those of microfibers (open structure, large pore size) and are therefore interesting as scaffolds for cellular infiltration.
