Dear community,

in the work of Wang et al [1] it was observed that gold nanoparticles (50nm) were transported to the apical surface of (cancer) cells:

"Most AuNPs were not taken up by the cells, but instead moved directly to the apical surfaces of the cells"

I really wondering if there is more known evidence for this behavior ? At least I cannot find anything.

Any help is appreciated!

Best,

Thorsten
