Hello Grizz and thanks for the vote of confidence. Though I'd be reluctant to call myself an expert on anything Colloidal Silver related as my experience and observations have been entirely subjective and/or theoretical at best.
That said, I have been privileged to have taken part in some rather exciting CS research over the course of the years. Which in turn, provided me with the opportunity to acquire some very helpful knowledge in the field of electrochemistry.
Beyond this, I'd add that my knowledge on the Science and biological reactions associated with Colloidal Silver in humans is quite limited. Though my observation has been, that the Ionic silver solutions have proven to be consistently superior to the particulate solutions in all aspects of use. Whether this was internal external(eye drops on our cat for example), or used internally, to treat flu's, colds and infections. Whereas the particulate solutions did not appear to be as effective and in some case not at all.
And while I have not verifiable data to offer, I'd add that my best guess is that this is likely due in part to the inherent characteristics and advantages that come with the ionic compounds, in contrast to the elemental solutions.
As for whether or not there are applications where elemental silver solutions are advantageous, I cannot say with any measure of conviction beyond what I've seen. Though the lab testing conducted by Mesosilver appears to indicate that the inherent differences between both solutions is negligible at best.
PS. I've been using my own CS solution as a conductivity primer for zapping(on wrists) for over four years, and on a daily basis, with very good success.
