In view of the problems that researchers have today in intentionally getting sufficient quantities of nanoparticles across the blood-brain barrier, it is rather unlikely that this happens unintentionally through other, not specially tailored nanoparticles.
An exception is the passage of nanoparticles through the olfactory nerve: this is where nanoparticles can get into the brain. However, all previous results from corresponding experiments indicate that the amount of nanoparticles that enter the brain either via the blood-brain barrier or via the olfactory nerve in the olfactory epithelium of the nose is very small. Further research efforts need to be carried out here.
