Figure 3From: Effective pulmonary delivery of an aerosolized plasmid DNA vaccine via surface acoustic wave nebulization Measured using laser diffraction (Spraytec, Malvern, UK), the size distribution of nebulized droplets using SAW at 30 MHz and 1 W of applied power from an aqueous suspensions of 10, 50 and 100 μ g/ml of pDNA indicates droplet size distributions generally less than 5 μ m, useful for deep lung deposition.
