Abstract: The present disclosure generally relates to cyclonic separation or filtering of nanoparticles suspended in a gas. A plume of liquid droplets may be generated using an ultrasound or other generator. The gas may be mixed with the plume of liquid droplets, which may have received an electrostatic charge prior to mixing, to promote preferential adhesion of the nanoparticles to the liquid droplets.
