Figure 3From: Dynamics of different-sized solid-state nanocrystals as tracers for a drug-delivery system in the interstitium of a human tumor xenograftTrajectories of nanoparticles in the perivascular region. The arrow indicates the direction of the movements of the nanoparticles. (a) Trajectories of the Quantum dot in the perivascular region. The trajectories are encoded on the time axis from blue to red. (b) Trajectories of three different-sized particles in the perivascular area.Back to article page
