Francis: Silver-chloride has antibacterial properties. They are reduced as compared to isolated silver, it is true.
http://www.medicaldevicesonline.com/features/story.epml?features.REF=47 However, I could say that a gun has little or no killing properties compared to a nuclear warhead, and be close to accurate. This wouldn't be being scientifically AUTHENTIC, though, would it? Here is another quote from a team of medical science doctors, in a study conducted to determine if coated catheters would be successful in-vivo: By Robert A. Jeanmenne, Jr., Caterpillar Inc., York, PA Mark DeLaurentis, MD., Memorial Hospital, Easton, MD Kambiz Pourrezaeik, Ph.D. and Richard B. Beard, Ph.D., Drexel University, Philadelphia, PA "The chemical reactions that help supply the silver ions are related to the good supply of chloride ions that already exists in the blood stream. When the silver metal undergoes oxidation and dissociates into the silver ion, it immediately reacts with the available chloride ions to form the compound silver chloride. It is thought the bacteria consume the silver ions. Once the silver ion becomes part of the chemistry of the bacteria, it dies." http://www.pfonline.com/articles/089704.html A quote from Renaissance Chemical LTD: "The result is a micro particulate 1- 3ยต composite sponge of sintered rutile titanium dioxide, containing sparingly soluble silver chloride. In an aqueous system an equilibrium develops between silver chloride and silver ions. 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. " There are sorts of theories on how silver ions transform through their passage through the body, and all sorts of methods that are being used to buffer silver ions in the bloodstream. Unfortunately, I haven't been able to figure them out yet. I suspect that there are those using potassium hydroxide in medical research, but that's only a guess... It might be magnesium, for all I know. I've spoken with numerous working chemists, all of which state that it's not as simple as ionic silver being converted to silver chloride. This includes a chemist I corresponded with a few years ago at Perdue University. None of them were even willing to proffer an opinion, stating that the variables involved were too great to directly address without concerted study, and they all suggested finding an organic chemist, all of which, apparently, are gainfully employed with little time on their hands. Now, if you could increase the direct bacterial efficacy of mesosilver, you would have a superior product without question. Considering all of the equipment at your disposal, why not try? It would be an interesting challenge, if nothing more. You could develop the ultimate silver solution, which still would contain 10PPM colloidal silver. I went back and examined your old website through the internet archive project. Apparently I was wrong. I thought at one time your website stated that silver particles cannot cause argyria, and I thought that your website stated that mesosilver was superior to ionic silver as used externally, by direct effect.
