Fig. 9From: A multiscale modeling study of particle size effects on the tissue penetration efficacy of drug-delivery nanoparticlesRepresentative travel paths of simulated nanoparticles. a Travel paths of 100 nanoparticles in the tissue domain. The particles are of identical size (100 nm radius). b A zoomed-in view showing a single particle travel path and its interaction with a cell boundary. Panel B corresponds to the small region in Panel A marked by a rectangleBack to article page
