Size distribution of saliva products from different outlets after acoustofluidic separation. A: Size distribution [obtained via nanoparticle tracking analysis (NTA)] of isolated saliva components from the exosome outlet. Most particles were smaller than 200 nm. B: Size distribution (obtained via NTA) of isolated saliva components from the submicrometer waste outlet. Most particles were between 200 and 600 nm. C: Size distribution (obtained via dynamic light scattering) of isolated saliva components from the micrometer waste outlet. Most particles were about 1 μm.
