ABSTRACT
Electrohydrodynamic methods, including electrospinning and electrospraying, have several advantages considering both technological aspects and the micro- and nanosize products.
During electrospinning, also called electrostatic fiber formation, fibers are created by electrostatic forces, while in the case of electrospraying, fine particles can be generated via the atomization of solutions by electrostatic forces. This chapter provides a comprehensive overview and a comparison of the physical background of the two processes and the operational parameters affecting product quality. In addition, a particular focus is done on the challenges regarding their pharmaceutical industrial applicability. The conclusion drawn from the extensive literature review highlights that the appearance of electrospun and electrosprayed products in medicines is already imminent. Furthermore, they can open up new avenues in product development in several critical cases.
