Abstract

Topography and microstructure engineering are rapidly evolving areas of importance forbiomedical and pharmaceutical remits. Here, PVA (Polyvinyl alcohol) microbubbles (diameter rangẽ126 to 414 μm) were used to fabricate beaded (beads-on) nanofibers using an electrohydrodynamicatomization (EHDA) technique. Mean fiber diameter, inter-bead distance, and aspect ratio (AR)were investigated by regulating EHDA process parameters. PVA fibers (diameter range ~233 to737 nm) were obtained possessing bead ARs in the range of ~10 to 56%. AR was used to modulatehydrophilicity and active release.
