Submicrometre size spheres prepared from biocompatible polymers are becoming increasingly popular in drug and gene delivery. This paper describes the preparation of polymeric spheres with a mean diameter of 0.4 μm with a polydispersivity index of 8%, using coaxial electrohydrodynamic atomization (CEHDA) microbubbling. An 18 wt.% solution of polymethylsilsesquioxane, a hydrophobic biocompatible polymer, was subjected to CEHDA microbubbling by passing air through the inner needle and polymer so...Expand abstract
