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

我们提出了一种概念设计，可在一个基于电流体动力雾化 (EHDA) 的独特系统中生成和输送纳米粒子，而不受收集器的限制。目前的 EHDA 双极配置由毛细管喷嘴和针组成，两者都充当发射器和彼此的参考电极。在外加电压下，毛细管喷嘴喷出液滴，而针通过电晕放电产生离子风。在喷涂过程中，液滴的电荷通过与反离子相互作用而显着降低，并被电晕放电积累的离子风的动量推离电极。因此，本技术可以在纳米医学的有效呼吸输送中产生有希望的应用。
