Ionic wind generator derived from a liquid filled capillary pin. Application to particle capture

A new fluid pin-based ionic wind generator applied to airborne pathogen collection combines the processes of air flow generation by ionic wind, electrospray and electrostatic particle collection. This new concept brings a breakthrough in integration as it combines these three phenomena with a single driving force in order to perform the four functions of an airborne pathogen sampler, namely air flow production, particle capture, sample phase transfer and collecting electrode decontamination. The characterizations presented in this article led to a proof of concept and demonstrated the deviceʹs performance for a compact and portable airborne pathogen collection system.
