Frank, I notice you did not reply to the reference: "Silver ion solubility in deionised water is 20-40ppb and in saline 2-4ppm. In the presence of microbes, silver ions bind to available enzyme thiol groups; thus altering the equilibrium and allowing more silver ions into solution. Silver is therefore available on demand to control microbiological activity."
which is probably the most important piece of information in the whole debate. You go on to say: > What in the body causes metallic silver to oxidize? They > don't say.

You would be aware of the studies done by Dr Flick of SilverLon and others, who also state that silver metal dissolves to silver ions in the presence of biological fluids, and is available for interaction with microbes. Biological chemistry is a good deal more complicated than the simple 'add salt to silver ions and watch the silver chloride precipitate', which is really just a petrii dish experiment, and so is invalid by your own criterion. I would say that the weight of evidence is that silver metal does emit ions in biological fluids. Besides that, is it established that the silver ion as bound to chloride in silver chloride, is not available for further interaction with the sulphur groups as found in pathogens? It is likely that the silver chloride produced in biological systems is of extremely small particle size (because of the speed of nucleation) and is completely different to silver chloride as added to a petrii dish, and may have a far greater microbial interaction, due to the greater surface area of small colloids, which it has quite possibly become. One might also add that the fate of silver particles has not been established by you. Silver metal is tarnished by sulphide, one of the anions found in blood plasma. Can you say without doubt that these particles do not form silver sulphide? Indeed, can you say without doubt that these particles are not oxidised exactly as questioned by you in your message? No one can say with certainty what happens to silver solutions or colloids in biological systems except perhaps Stephen Quinto (and he is not telling), but it is quite clear that practically all forms of electro-generated CS work quite well.
