Hydrodynamic Sizes Relative to Airborne Sizes of Metal Oxide Particles Particles in dry form were found to be smaller than 1000 nm for fine zinc oxide dust and 50 to 70 nm for ultrafine zinc oxide dust (7). Particles were sonicated for 30 minutes. When suspended in distilled water, 20% of the ultrafine (nano) zinc oxide particles were suspended, with an average hydrodynamic diameter of 170 to 250 nm. When suspended in tissue culture media 45% had an average hydro-dynamic diameter of 300 to 400 nm. Tissue culture media suspended or extracted two to three times more particle mass than did dilute buffer or deionized distilled water, because of hydrodynamic action of media minerals. Hydrodynamic diameters were only modestly larger in tissue culture media than in distilled water (7).
