Several studies I have seen attribute most, if not all, of the
antimicrobial activity of silver particles to the formation of silver
oxide on the particle in the bloodstream. One example:
http://www.fpl.fs.fed.us/documnts/pdf2004/fpl_2004_dorau001.pdf
"Note that all these mechanisms relate to solvated silver ions, Ag+. The
antibacterial properties of any metal come from its ions, which are
generated from the neutral metal (1 5). In the presence of oxygen,
metallic silver can be bactericidal because silver (I) oxide is soluble
enough to release free silver ions (18). When dealing with metallic
silver, though, it is important to note that antimicrobial activity
depends on the extent of the active silver surface."
Would it not then be desirable to form silver oxide on the particles
that do form in EIS?

Maybe..but where and when?
IN the blood stream or in the jar?..or does it matter?
Ion exchange and reaction chains are a complicated deal and there's nothing
at all simple about where the CS is headed.
I suppose that any number of reactions will wind up doing the same thing.
Is yellow CS "bad" ?? Hellifino. If it works, use it. Even if the
oxides do nothing, there's lots of other stuff in there.

["Color" part not true, but particles do reflect light and ions
don't. Although particle size can have an effect on color and
numbers/density on depth of color, it's more an indication of the
chemical
composition of the majority of particles. If the color is yellow to
brown
to black, it mostly means that you have silver oxides in the water and
the
best way I've found to do that is to use too much current over too small
electrodes..you can actually see the oxides being formed in the water
rather than nearly all of it being stuck on the electrode that gets
black
as a "golden mist"]
