RE: Well... you already admitted that your nanoparticle solutions need to be tested.
The correct statement was, that I might get it tested in the future if not only for the sake of having a second opinion. :)
That said, since I know the chemistry of my solutions intimately as a result of measuring the total silver in solutions on numerous occasions. I have all the confidence in the world as to what my CS solution are made of and what's in them.
However, what I actually meant by "testing", was to actually test the products effectiveness against illnesses etc. As diluting a solution in itself, really doesn't mean anything without considering it's effectiveness.
