The aim of this appliation was to investigate the abundance of nanoparticles in the mouthwash, before and after use, by analysis of the solutions using asymmetric flow field-flow fractionation (AF4) coupled to both dynamic light scattering (DLS) and ultraviolet (UV) detectors.

Four independent samples were analyzed:

  1. The original mouthwash solution
  2. The mouthwash after 1 min of rinsing in the mouth
  3. The mouthwash after 3 min of rinsing in the mouth
  4. Blank saliva sample before mouthwash use
