Electrospray propelled by ionic wind in a bipolar system for direct delivery of charge reduced nanoparticles

Abstract We present a conceptual design to generate and deliver nanoparticles in one unique system based on electrohydrodynamic atomisation (EHDA) without the restriction of collector. The EHDA bipolar configuration consists capillary nozzle pin, both act as emitters reference electrodes each other. Under an applied voltage, sprays droplets while pin generates ion wind via corona discharge. During spraying process, droplets’ charge is significantly reduced by interacting with counter ions propelled away from momentum winds accumulated Thus, technique can yield promising applications effective respiratory delivery nanomedicine.
