The effect of nanoparticle size on their permeability across the in vitro BBB model following its exposure to FUS. (a) TEM images of synthesized AuNPs with diameters of 3, 15, and 120 nm. Scale bar is 20 nm. (b) The amount of 3, 15, and 120 nm AuNPs that permeated across the in vitro BBB model following its exposure to FUS in the presence of MBs. The effect of treatment with 10 μM Reg was also evaluated for comparison. The control group was the BBB model without any treatment. **p < 0.01; *p < 0.05; N.S., not significant. N = 4.
