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.
