If you look at the blood brain barrier, it is constructed so that nothing is suppose to pass through. Then there are specific transport mechanisms that allow certain elements and compounds to cross it, such as amino acids, water, salt, iron, calcium and so forth. For the most part if there is no transport mechanism provided for something, it cannot get across, or at least the seems to be the intention, although several things can cross that should not be able to, such as mercury. :<
If there is additional information to the contrary please let me know, I have a research library near by that I can go to as well, but from everything I have read, it appears that silver is both unable to cross the barrier, and is toxic to the neurons in the brain. As far as size, the barrier prevents silver ATOMS from crossing, so a colloid would be larger and even more difficult to pass through. Mind you these were two references I found in a few minutes searching, I don't think either I had seen before. If I run across any more references I will let you know. As far as sterling, that would have mostly copper in addition to silver, which is toxic in its own right. I do not know if it is able to cross or not, having not researched it.
