Figure 4From: The effect of nanoparticle size on the probability to cross the blood-brain barrier: an in-vitro endothelial cell model DLS size distribution analysis for (A) 20, (B) 50, (C) 70 and (D) 110 nm GNPs. The average sizes obtained from the DLS were 23 ± 13, 65 ± 22, 84 ± 26 and 120 ± 30 nm for the 20, 50, 70 and 110 nm GNPs, respectively.Back to article page
