Precise deposition of electrospun nanofibers and electrospraying of nanoparticles as enabling techniques for biomedical engineering applications

Abstract

Electro hydrodynamic methods like electrospinning of nanofibers and electrospraying of ceramic nanoparticle layers find various applications in medical engineering. The aim of this study is the optimization and comparison of the controllability and precision of electrospinning and electrospraying processes. Different methods like for example the specific modification of the electric field by additional electrodes, by changing the collector size etc. and their combinations to control the deposition area of both electrospinning and electrospraying are presented. Stable and precise processes are of highest importance for transferring the techniques of electrospinning and electrospraying from the state of research to mass production. © 2009 Springer-Verlag.
