Figure 8From: ISDD: A computational model of particle sedimentation, diffusion and target cell dosimetry for in vitro toxicity studiesMedia Height Effects on the Extent of Transport. ISDD calculated fraction of nano- and micron scale TiO2 particles delivered to cells over the duration of a 24 hour in vitro study as a function of media height. Increases in media height reduce the fraction of the administered dose reaching cells, particularly for nanoparticles, where diffusion drives transport.Back to article page
