"traveling ultrasound waves would be used... propulsion of nanoparticles depends on their orientation... particles will behave in applications and that the propulsion has the right properties for the particles to actually be used in these applications... nanoparticles could move through the bloodstream without blocking up the finest blood vessels... propulsion is also suitable for other fluids and for tissue"
