Visualization of nasal powder distribution using biomimetic human nasal cavity model

“…In order to prevent the entrainment phenomenon caused by particle rebound during the test, which may cause loss and distribution measurement error and affect the experimental results, it is necessary to select a suitable coating solution for the device to simulate the moist environment of the nasal cavity 36 . The results showed that the deposition area was higher in the posterior nasal septum and posterior inferior nasal concha for both blank and artificial mucus, and part of the powder fell into the nasopharynx ( Fig.…”
